God softwares for solarcell engineerss1/24/2024 The Purdue Research Foundation Office of Technology Commercialization operates one of the most comprehensive technology transfer programs among leading research universities in the U.S. Ībout Purdue Research Foundation Office of Technology Commercialization See how Purdue never stops in the persistent pursuit of the next giant leap at. Committed to affordability and accessibility, Purdue has frozen tuition and most fees at 2012-13 levels, enabling more students than ever to graduate debt-free. Committed to hands-on and online, real-world learning, Purdue offers a transformative education to all. News & World Report, Purdue delivers world-changing research and out-of-this-world discovery. Ranked in each of the last five years as one of the 10 Most Innovative universities in the United States by U.S. Purdue University is a top public research institution developing practical solutions to today’s toughest challenges. Department of Energy’s Solar Energy Technologies Office, Purdue’s College of Engineering and the Davidson School of Chemical Engineering. Dou and his team received funding and other support to conduct their research from the U.S. Industry partners interested in further developing the technology for the marketplace should contact Will Buchanan, about 2023.ĭou’s research was published in the July 2021 issue of Advanced Materials and the January 2021 issue of Angewandte Chemie. We look to achieve these goals within a year or so.”ĭou disclosed the conjugated ligand innovation to the Purdue Research Foundation Office of Technology Commercialization, which has applied for patent protection on the intellectual property. “We also are working to apply the ligands in larger-area solar modules. “We are working on new ligands to further what we’ve already achieved: more than 25% power conversion efficiency and more than 10,000 hours of operational lifetime,” Dou said. “We also improved the lifetime to more than 2,400 hours tested at 65 degrees Celsius, which is four times longer than without the ligands.”ĭou and his team are taking additional steps to improve the ligands. “We achieved near 25% power conversion efficiency with the ligands, compared to less than 20% without them,” Dou said. “Our conjugated ligands have a perfect fit into the perovskite crystal lattice and can help build a 2D-on-3D perovskite heterostructure, which further enhances the solar panel’s stability,” Dou said.ĭou and his team have tested the innovative ligands in their laboratory. He said a molecular “glue” is needed, but conventional molecules block the current flow. ![]() Replacing the panels also adds to the labor cost.”ĭou said traditional solar cells require a critical interface between perovskite and the organic charge collection layer. Perovskite may not be stable for 25 years like silicon, but at least 10 years is required for successful commercialization. ![]() “Poor stability means a shorter product lifetime, and consumers will need to replace a panel more frequently. ![]() “These solar cells lack an effective charge transfer and are unstable and vulnerable under prolonged light exposure, which often leads to degradation,” Dou said. But Letian Dou, the Charles Davidson Associate Professor of Chemical Engineering in the Davidson School of Chemical Engineering, said perovskite solar cells have traits that limit their effectiveness. They can be made lightweight and mechanically flexible and portable. Perovskite solar panels are also much thinner and lighter than silicon panels, making the transportation and installation cost lower. Perovskite can be manufactured as solar cells with simple techniques similar to printing newspapers the techniques cost less and use less energy than those used to produce traditional silicon cells. ![]() Perovskite is a material that can be formed from different elements to have a variety of electrical, optical and physical characteristics. – Purdue University researchers have created new, multifunctional ligands that improve the charge transfer, power conversion capability and long-term stability of perovskite solar cells. New semiconducting ligands reach 25% solar cell power conversion
