Imec, Polyera and Solvay set 8.3% efficiency record for organic solar
Imec has developed a proprietary inverted bulk heterojunction architecture for polymer-based solar cells that simultaneously optimizes cell light management and increases device stability. With this architecture, and a proprietary Polyera semiconductor in the photoactive layer, a team of imec and Solvay researchers now announces a certified conversion efficiency of 8.3%. This is the highest certified efficiency reported to date in the world for inverted polymer cell architectures. This result follows previous reports on imec’s proprietary device architecture, proving that scalable inverted device architectures are applicable to a variety of polymer materials. Although further improvements of efficiency and lifetime are required to bring this potentially-revolutionary technology to market, inverted device architectures offer a number of commercially-relevant benefits over standard architectures. As such, this milestone represents another advancement towards commercially-viable organic solar panels.
Tom Aernouts, R&D Team Leader Organic Photovoltaics at imec: “These excellent results are the fruit of an intense collaboration between Solvay, imec and Polyera. It is remarkable to see how the inverted architecture adds to the performance of these cells! This shows how crucial the combination of high-level device technology and next-generation materials will be to bring organic solar cells to the market.”
