"We've solved several engineering problems to achieve record results across a large surface area of interconnected modules.</p> <p>"Roll-to-roll printing allows for the solar cells to be manufactured on very long, continuous rolls of plastic, which can dramatically increase the rate of production. As these methods are already widely used in the printing industry, this makes their production more accessible for Australian manufacturers. The successful commercialization of printed flexible solar cells has the potential to create significant economic and environmental benefits for Australia and the world."</p> <p>he results were achieved in collaboration with researchers from the University of Cambridge, Monash University, the University of Sydney and the University of New South Wales, and have been published in the journal Nature Communications.</p> <p>CSIRO Principal Research Scientist Dr. Doojin Vak said that an automated system produced a comprehensive dataset that will pave the way to use machine learning in future research.</p> <p>"We developed a system for rapidly producing and testing over ten thousand solar cells a day—something that would have been impossible to do manually," Dr. Vak said. "This allowed us to identify the optimal settings for the various parameters in the roll-to-roll process and quickly pinpoint the conditions that deliver the best results."</p> <p>Incorporating an advanced material called perovskite, CSIRO's printed solar is different from the silicon solar panels found on Australian roofs.</p> <p>"Perovskites are a class of emerging solar cell material. They're remarkable because they can be formulated into inks and used in industrial printers," Dr. Vak said. "We've also alleviated the need to use expensive metals, such as gold, in their production by using specialized carbon inks, which further reduces production costs."</p> <p>Acknowledging that perovskite solar cells currently trail silicon solar panels in efficiency and lifetime when produced at scale, Dr. Chesman sees the application of flexible panels to be very different.</p> <p>"As these perovskite solar cells are printed onto plastic films, they are very lightweight, highly flexible and portable," he said. "The rigidity and weight of conventional silicon solar panels can make moving them difficult. Our thin, lightweight solar can be easily transported anywhere there is sun. We even sent the solar panels to space last week to test their performance, with a view to further optimize and ultimately provide a reliable energy source for future space endeavors."</p> <p>CSIRO is actively seeking industry partners to further develop and commercialize this technology.</p> </div> <br /> </div> </div> </div> <div class="fl show-keywords_small"> <h2 class="t title-ff fwb fz18 black tr show-keywords-title p20 fl"> Keywords </h2> <div class="fr fz18 keywords"> <i class="iconfont icon-icon-down"></i> <a href="https://www.world-energy.org/search.html?keyword=energy efficiency">Energy Efficiency</a> </div> <div class="fr fz18 keywords"> <div class="fixedad ad mt10 mb30" style="width: 630px;
