The thicknesses of all the deposited materials were measured with the help of Ellipsometry. The IV graphs were drawn in order to observe the current voltage output. The efficiency of the cell was graphed with the fill factor as well (graphs not given here). The efficiency came out to be approximately 16.5 % and the CIGS (copper-indium–gallium-selenide) maximum efficiency is 20 %. The efficiency of a solar cell can further be enhanced by adapting quality materials, good experimental devices and proper procedures.

The precursor aqueous bath contained 1 mole of lead nitrate, 1 mole of Thiourea and complexing agents (triethanolamine (TEA) and NaOH). Bath temperature and deposition time were fixed at 60°C and 3 hours, respectively. However, the PH of bath was varied from 10.5 to 12.5. Structural properties of the deposited films were characterized by X-ray diffraction and Raman spectroscopy. The preferred direction was revealed to be along (111) and the PbS crystal structure was confirmed. Strains and grains sizes were also calculated. Optical studies showed that films thicknesses do not exceed 600nm. Energy band gap values of films decreases with increase in pH and reached a value ~ 0.4eV at pH equal 12.5. The small value of the energy band gap makes PbS one of the most interesting candidate for solar energy conversion near the infrared ray. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CBD" title="CBD">CBD</a>, <a href="https://publications.waset.org/abstracts/search?q=PbS" title=" PbS"> PbS</a>, <a href="https://publications.waset.org/abstracts/search?q=pH" title=" pH"> pH</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=x-ray%20diffraction" title=" x-ray diffraction"> x-ray diffraction</a> </p> <a href="https://publications.waset.org/abstracts/29510/structural-optical-and-electrical-properties-of-pbs-thin-films-deposited-by-cbd-at-different-bath-ph" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29510.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">442</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5291</span> Effect of Temperature on the Structural and Optical Properties of ZnS Thin Films Obtained by Chemical Bath Deposition in Acidic Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Merzouk">Hamid Merzouk</a>, <a href="https://publications.waset.org/abstracts/search?q=Dajhida%20Talantikite"> Dajhida Talantikite</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Tounsi"> Amel Tounsi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thin films of ZnS have been deposited by chemical route into acidic medium.

Taguchi technique has been used for the analysis. In the experiment, nickel chloride which is a source of nickel when mixed with sodium hypophosphite has been used as the reducing agent and the source of phosphate and sodium hydroxide has been used to vary the pH of the coating bath. The coated samples are tested for impact energy by conducting impact test. Finally, the effects of coating bath parameters on the impact energy absorbed have been plotted, and analysis has been carried out. Further, percentage contribution of coating bath parameters using Design of Experiments approach (DOE) has been analysed. Finally, it can be concluded that the bath parameters of the Ni-P coating will certainly influence on the strength of the specimen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bath%20parameters" title="bath parameters">bath parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=coatings" title=" coatings"> coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment" title=" design of experiment"> design of experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20toughness" title=" fracture toughness"> fracture toughness</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20strength" title=" impact strength"> impact strength</a> </p> <a href="https://publications.waset.org/abstracts/59952/experimental-investigation-on-the-effects-of-electroless-nickel-phosphorus-deposition-ph-and-temperature-with-the-varying-coating-bath-parameters-on-impact-energy-by-taguchi-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59952.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">351</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5286</span> Study Of Cu Doped Zns Thin Films Nanocrystalline by Chemical Bath Deposition Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Merzouka">H.

The CdS thin films were annealed in air, argon, hydrogen and nitrogen for 1 h at various temperatures (300, 350, 400, 450 and 500 °C). The changes in optical and electrical properties of annealed treated CdS thin films were analyzed. The results showed that, the band-gap and resistivity depend on the post-deposition annealing atmosphere and temperatures. Thus, it was found that these properties of the films, were found to be affected by various processes with opposite effects, some beneficial and others unfavorable. The energy gap and resistivity for different annealing atmospheres was seen to oscillate by thermal annealing. Recrystallization, oxidation, surface passivation, sublimation and materials evaporation were found the main factors of the heat-treatment process responsible for this oscillating behavior. Annealing over 400 °C was seen to degrade the optical and electrical properties of the film. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cds" title="cds">cds</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=annealing" title=" annealing"> annealing</a>, <a href="https://publications.waset.org/abstracts/search?q=optical" title=" optical"> optical</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20properties" title=" electrical properties"> electrical properties</a> </p> <a href="https://publications.waset.org/abstracts/31251/characterization-of-chemically-deposited-cds-thin-films-annealed-in-different-atmospheres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31251.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">510</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5283</span> The Effect of Bath Composition for Hot-Dip Aluminizing of AISI 4140 Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aptullah%20Karakas">Aptullah Karakas</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Baydogan">Murat Baydogan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hot-dip aluminizing (HDA) is one of the several aluminizing methods to form a wear-, corrosion- and oxidation-resistant aluminide layers on the surface. In this method, the substrate is dipped into a molten aluminum bath, hold in the bath for several minutes, and cooled down to the room temperature in air. A subsequent annealing after the HDA process is generally performed. The main advantage of HDA is its very low investment cost in comparison with other aluminizing methods such as chemical vapor deposition (CVD), pack aluminizing and metalizing. In the HDA process, Al or Al-Si molten baths are mostly used. However, in this study, three different Al alloys such as Al4043 (Al-Mg), Al5356 (Al-Si) and Al7020 (Al-Zn) were used as the molten bath in order to see their effects on morphological and mechanical properties of the resulting aluminide layers. AISI 4140 low alloyed steel was used as the substrate. Parameters of the HDA process were bath composition, bath temperature, and dipping time. These parameters were considered within a Taguchi L9 orthogonal array. After the HDA process and subsequent diffusion annealing, coating thickness measurement, microstructural analysis and hardness measurement of the aluminide layers were conducted. The optimum process parameters were evaluated according to coating morphology, such as cracks, Kirkendall porosity and hardness of the coatings. According to the results, smooth and clean aluminide layer with less Kirkendall porosity and cracks were observed on the sample, which was aluminized in the molten Al7020 bath at 700 C for 10 minutes and subsequently diffusion annealed at 750 C. Hardness of the aluminide layer was in between 1100-1300 HV and the coating thickness was approximately 400 µm. The results were promising such that a hard and thick aluminide layer with less Kirkendall porosity and cracks could be formed. It is, therefore, concluded that Al7020 bath may be used in the HDA process of AISI 4140 steel substrate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot-dip%20aluminizing" title="hot-dip aluminizing">hot-dip aluminizing</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness%20measurement" title=" hardness measurement"> hardness measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20annealing" title=" diffusion annealing"> diffusion annealing</a> </p> <a href="https://publications.waset.org/abstracts/174006/the-effect-of-bath-composition-for-hot-dip-aluminizing-of-aisi-4140-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174006.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5282</span> Microstructural and Optical Characterization of Heterostructures of ZnS/CdS and CdS/ZnS Synthesized by Chemical Bath Deposition Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temesgen%20Geremew">Temesgen Geremew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> ZnS/glass and CdS/glass single layers and ZnS/CdS and CdS/ZnS heterojunction thin films were deposited by the chemical bath deposition method using zinc acetate and cadmium acetate as the metal ion sources and thioacetamide as a nonmetallic ion source in acidic medium.

The microstructure evolution of films and nanostructures is closely related with the size distribution of charged nanoparticles. To confirm the generation of charged nanoparticles during GaN, the generation of GaN charged nanoparticles was examined in an atmospheric pressure CVD process using a Differential Mobility Analyser (DMA) combined with a Faraday Cup Electrometer (FCE). It was confirmed that GaN charged nanoparticles were generated under the condition where GaN nanostructures were synthesized on the bare and Au-coated Si substrates. In addition, the deposition behaviour depends strongly on the charge transfer rate of metal substrates. On the metal substrates of a lower CTR such as Mo, the deposition rate of GaN was much lower than on those of a higher CTR such as Fe. GaN nanowires tend to grow on the substrates of a lower CTR whereas GaN thin films tend to be deposited on the substrates of a higher CTR. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20vapour%20deposition" title="chemical vapour deposition">chemical vapour deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=charged%20cluster%20model" title=" charged cluster model"> charged cluster model</a>, <a href="https://publications.waset.org/abstracts/search?q=generation%20of%20charged%20nanoparticles" title=" generation of charged nanoparticles"> generation of charged nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=deposition%20behaviour" title=" deposition behaviour"> deposition behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=nanostructures" title=" nanostructures"> nanostructures</a>, <a href="https://publications.waset.org/abstracts/search?q=gan" title=" gan"> gan</a>, <a href="https://publications.waset.org/abstracts/search?q=charged%20transfer%20rate" title=" charged transfer rate"> charged transfer rate</a> </p> <a href="https://publications.waset.org/abstracts/2530/generation-of-charged-nanoparticles-in-the-gas-phase-and-their-contribution-to-deposition-of-gan-films-and-nanostructures-during-atmospheric-pressure-chemical-vapor-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2530.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">439</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5280</span> Ni-W alloy Coatings: A Promising Electrode Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mr.%20Liju%20Elias">Mr. Liju Elias</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Chitharanjan%20Hegde"> A.

The deposition conditions for production of Ni-W coatings have been optimized for peak performance of their electrocatalytic activity, namely hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The corrosion behavior of the coatings were tested under working conditions of electrocatalysis (1M KOH). Electrocatalytic behaviours were tested by cyclic voltammetry and chrono-potentiometry techniques. Experimental results demonstrated that Ni-W coatings at low and high current densities (c. d.) showing superior performance for OER and HER respectively. The increased electrocatalytic activity for HER with increase of deposition c. d. was attributed to the phase structure, surface morphology and chemical composition of the coatings, confirmed by XRD, SEM and EDX analysis, respectively. The dependency of hardness and thickness of the coatings on HER and OER were examined, and results were discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocatalytic%20behavior" title="electrocatalytic behavior">electrocatalytic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=HER" title=" HER"> HER</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni-W%20alloy" title=" Ni-W alloy"> Ni-W alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=OER" title=" OER"> OER</a> </p> <a href="https://publications.waset.org/abstracts/17794/ni-w-alloy-coatings-a-promising-electrode-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17794.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">416</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5279</span> Thorium-Doped PbS Thin Films for Radiation Damage Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Shandalov">Michael Shandalov</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzvi%20Templeman"> Tzvi Templeman</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Schmidt"> Michael Schmidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Itzhak%20Kelson"> Itzhak Kelson</a>, <a href="https://publications.waset.org/abstracts/search?q=Eyal%20Yahel"> Eyal Yahel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present a new method to produce a model system for the study of radiation damage in non-radioactive materials. The method is based on homogeneously incorporating 228Th ions in PbS thin films using a small volume chemical bath deposition (CBD) technique. The common way to alloy metals with radioactive elements is by melting pure elements, which requires considerable amounts of radioactive material with its safety consequences such as high sample activity. Controlled doping of the thin films with (very) small amounts (100-200ppm) of radioactive elements such as thorium is expected to provide a unique path for studying radiation damage in materials due to decay processes without the need of sealed enclosure. As a first stage, we developed CBD process for controlled doping of PbS thin films (~100 nm thick) with the stable isotope (t1/2~106 years), 232Th. Next, we developed CBD process for controlled doping of PbS thin films with active 228Th isotope. This was achieved by altering deposition parameters such as temperature, pH, reagent concentrations and time. The 228Th-doped films were characterized using X-ray diffraction, which indicated a single phase material. Film morphology and thickness were determined using scanning electron microscopy (SEM). Energy dispersive spectroscopy (EDS) mapping in the analytical transmission electron microscope (A-TEM), X-ray photoelectron spectroscopy (XPS) depth profiles and autoradiography indicated that the Th ions were homogeneously distributed throughout the films, suggesting Pb substitution by Th ions in the crystal lattice. The properties of the PbS (228Th) film activity were investigated by using alpha-spectroscopy and gamma spectroscopy. The resulting films are applicable for isochronal annealing of resistivity measurements and currently under investigation. This work shows promise as a model system for the analysis of dilute defect systems in semiconductor thin films. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title="thin films">thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=doping" title=" doping"> doping</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20damage" title=" radiation damage"> radiation damage</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20bath%20deposition" title=" chemical bath deposition"> chemical bath deposition</a> </p> <a href="https://publications.waset.org/abstracts/31401/thorium-doped-pbs-thin-films-for-radiation-damage-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31401.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">393</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5278</span> Chemical Vapor Deposition (CVD) of Molybdenum Disulphide (MoS2) Monolayers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Omar">Omar Omar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan%20Jun"> Yuan Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Jinghua"> Hong Jinghua</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Chuanhong"> Jin Chuanhong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work molybdenum dioxide (MoO2) and sulphur powders are used to grow MoS2 mono layers at elevated temperatures T≥800 °C.

Metal ion-doped CuS thin film was prepared by the chemical bath deposition (CBD) method on FTO substrate and used directly as counter electrodes for TiO₂/CdS/CdSe/ZnS photoanodes based QDSSCs. For the Ca-doped CuS thin films, copper nitrate and thioacetamide were used as anionic and cationic precursors. Calcium nitrate tetrahydrate was used as doping material. The surface morphology of Ca-doped CuS CEs indicates that the fragments are uniformly distributed, and the structure is densely packed with high crystallinity. The changes observed in the diffraction patterns suggest that Ca dopant can introduce increased disorder into CuS material structure. EDX analysis was employed to determine the elemental identification, and the results confirmed the presence of Cu, S, and Ca on the FTO glass substrate. The photovoltaic current density – voltage characteristics of Ca-doped CuS CEs shows the specific improvements in open circuit voltage decay (Voc) and short-circuit current density (Jsc). Electrochemical impedance spectroscopy results display that Ca-doped CuS CEs have greater electrocatalytic activity and charge transport capacity than bare CuS. All the experimental results indicate that 20% Ca-doped CuS CE based QDSSCs exhibit high power conversion efficiency (η) of 4.92%, short circuit current density of 15.47 mA cm⁻², open circuit photovoltage of 0.611 V, and fill factor (FF) of 0.521 under illumination of one sun. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ca-doped%20CuS%20counter%20electrodes" title="Ca-doped CuS counter electrodes">Ca-doped CuS counter electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20morphology" title=" surface morphology"> surface morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20bath%20deposition%20method" title=" chemical bath deposition method"> chemical bath deposition method</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocatalytic%20activity" title=" electrocatalytic activity"> electrocatalytic activity</a> </p> <a href="https://publications.waset.org/abstracts/86817/highly-efficient-ca-doped-cus-counter-electrodes-for-quantum-dot-sensitized-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86817.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5275</span> Adsorption-desorption Behavior of Weak Polyelectrolytes Deposition on Aminolyzed-PLA Non-woven</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sima%20Shakoorjavan">Sima Shakoorjavan</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawid%20Stawski"> Dawid Stawski</a>, <a href="https://publications.waset.org/abstracts/search?q=Somaye%20Akbari"> Somaye Akbari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the adsorption-desorption behavior of poly(amidoamine) (PAMAM) as a polycation and poly (acrylic acid) (PAA) as a polyanion deposited on aminolyzed-PLA nonwoven through layer-by-layer technique (lbl) was studied. The adsorption-desorption behavior was monitored by UV adsorbance spectroscopy and turbidity tests of the waste polyelectrolytes after each deposition. Also, the drying between each deposition step was performed to study the effect of drying on adsorption-desorption behavior. According to UV adsorbance spectroscopy of the waste polyelectrolyte after each deposition, it was revealed that drying has a great effect on the deposition behavior of the next layer. Regarding the deposition of the second layer, drying caused more desorption and removal of the previously deposited layer since the turbidity and the absorbance of the waste increased in comparison to pure polyelectrolyte. To deposit the third layer, the same scenario occurred and drying caused more removal of the previously deposited layer. However, the deposition of the fourth layer drying after the deposition of the third layer did not affect the adsorption-desorption behavior. Since the adsorbance and turbidity of the samples that were dried and those that were not dried were the same. As a result, it seemed that deposition of the fourth layer could be the starting point where lbl reached its constant state. The decrease in adsorbance and remaining turbidity of the waste same as a pure polyelectrolyte can indicate that most portion of the polyelectrolyte was adsorbed onto the substrate rather than complex formation in the bath as the subsequence of the previous layer removal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adsorption-desorption%20behavior" title="Adsorption-desorption behavior">Adsorption-desorption behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=lbl%20technique" title=" lbl technique"> lbl technique</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28amidoamine%29" title=" poly(amidoamine)"> poly(amidoamine)</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%20%28acrylic%20acid%29" title=" poly (acrylic acid)"> poly (acrylic acid)</a>, <a href="https://publications.waset.org/abstracts/search?q=weak%20polyelectrolytes" title=" weak polyelectrolytes"> weak polyelectrolytes</a> </p> <a href="https://publications.waset.org/abstracts/176722/adsorption-desorption-behavior-of-weak-polyelectrolytes-deposition-on-aminolyzed-pla-non-woven" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176722.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">53</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5274</span> Role of Chloride Ions on The Properties of Electrodeposited ZnO Nanostructures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Mentar">L.

With the development of film growth technologies and intense recent interest in nanotechnology, several varieties of ZnO nanostructured materials have been synthesized almost exclusively by thermal evaporation methods, particularly chemical vapor deposition (CVD), which generally require a high growth temperature above 550 °C. In contrast, wet chemistry techniques such as hydrothermal synthesis and electro-deposition are promising alternatives to synthesize ZnO nanostructures, especially at a significantly lower temperature (below 200°C). In this study, the electro-deposition method was used to produce zinc oxide (ZnO) nanostructures on fluorine-doped tin oxide (FTO)-coated conducting glass substrate from chloride bath. We present the influence of KCl concentrations on the electro-deposition process, morphological, structural and optical properties of ZnO nanostructures. The potentials of electro-deposition of ZnO were determined using the cyclic voltammetry. From the Mott-Schottky measurements, the flat-band potential and the donor density for the ZnO nanostructure are determined. Field emission scanning electron microscopy (FESEM) images showed different sizes and morphologies of the nanostructures which depends on the concentrations of Cl-. Very netted hexagonal grains are observed for the nanostructures deposited at 0.1M of KCl. X-ray diffraction (XRD) study confirms the Wurtzite phase of the ZnO nanostructures with a preferred oriented along (002) plane normal to the substrate surface. UV-Visible spectra showed a significant optical transmission (~80%), which decreased with low Cl-1 concentrations. The energy band gap values have been estimated to be between 3.52 and 3.80 eV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cl-" title="Cl-">Cl-</a>, <a href="https://publications.waset.org/abstracts/search?q=electro-deposition" title=" electro-deposition"> electro-deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=FESEM" title=" FESEM"> FESEM</a>, <a href="https://publications.waset.org/abstracts/search?q=Mott-Schottky" title=" Mott-Schottky"> Mott-Schottky</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO" title=" ZnO"> ZnO</a> </p> <a href="https://publications.waset.org/abstracts/33048/role-of-chloride-ions-on-the-properties-of-electrodeposited-zno-nanostructures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33048.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">289</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5273</span> Effect of the Deposition Time of Hydrogenated Nanocrystalline Si Grown on Porous Alumina Film on Glass Substrate by Plasma Processing Chemical Vapor Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Laatar">F.

The optimization of the operating parameters made it possible to obtain a stable Ni-P alloy deposition formulation. To understand the reaction mechanism of the deposition process, a kinetic study was performed by cyclic voltammetry and by electrochemical impedance spectroscopy (EIS). The coatings obtained have a very high corrosion resistance in a very aggressive acid medium which increases with the heat treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyclic%20voltammetry" title="cyclic voltammetry">cyclic voltammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=EIS" title=" EIS"> EIS</a>, <a href="https://publications.waset.org/abstracts/search?q=electroless%20Ni%E2%80%93P%20coating" title=" electroless Ni–P coating"> electroless Ni–P coating</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatment" title=" heat treatment"> heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=potentiodynamic%20polarization" title=" potentiodynamic polarization"> potentiodynamic polarization</a> </p> <a href="https://publications.waset.org/abstracts/63389/influence-of-sodium-acetate-on-electroless-ni-p-deposits-and-effect-of-heat-treatment-on-corrosion-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63389.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5270</span> Photoelectrochemical Water Splitting from Earth-Abundant CuO Thin Film Photocathode: Enhancing Performance and Photo-Stability through Deposition of Overlayers </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wilman%20Septina">Wilman Septina</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajiv%20R.%20Prabhakar"> Rajiv R.

It is a p-type semiconductor with a band gap of around 1.5 eV, absorbing a significant portion of the solar spectrum. One of the main challenges in using CuO as solar absorber in an aqueous system is its tendency towards photocorrosion, generating Cu2O and metallic Cu. Although there have been several reports of CuO as a photocathode for hydrogen production, it is unclear how much of the observed current actually corresponds to H2 evolution, as the inevitability of photocorrosion is usually not addressed. In this research, we investigated the effect of the deposition of overlayers onto CuO thin films for the purpose of enhancing its photostability as well as performance for water splitting applications. CuO thin film was fabricated by galvanic electrodeposition of metallic copper onto gold-coated FTO substrates, followed by annealing in air at 600 °C. Photoelectrochemical measurement of the bare CuO film using 1 M phosphate buffer (pH 6.9) under simulated AM 1.5 sunlight showed a current density of ca. 1.5 mA cm-2 (at 0.4 VRHE), which photocorroded to Cu metal upon prolonged illumination. This photocorrosion could be suppressed by deposition of 50 nm-thick TiO2, deposited by atomic layer deposition. In addition, we found that insertion of an n-type CdS layer, deposited by chemical bath deposition, between the CuO and TiO2 layers was able to enhance significantly the photocurrent compared to without the CdS layer. A photocurrent of over 2 mA cm-2 (at 0 VRHE) was observed using the photocathode stack FTO/Au/CuO/CdS/TiO2/Pt. Structural, electrochemical, and photostability characterizations of the photocathode as well as results on various overlayers will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CuO" title="CuO">CuO</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=photoelectrochemical" title=" photoelectrochemical"> photoelectrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=photostability" title=" photostability"> photostability</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20splitting" title=" water splitting"> water splitting</a> </p> <a href="https://publications.waset.org/abstracts/54277/photoelectrochemical-water-splitting-from-earth-abundant-cuo-thin-film-photocathode-enhancing-performance-and-photo-stability-through-deposition-of-overlayers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54277.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">224</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5269</span> The Combined Effect of the Magnetic Field and Ammonium Chlorides on Deposits Zn-Ni Obtained in Different Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.Benachour">N.Benachour</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Chouchane"> S.
