World-record efficiency achieved by Polyera organic solar cell

In California, Polyera Corporation has achieved a certified world-record 5.2% efficient fully-polymeric organic solar cell in an inverted bulk heterojunction architecture combining their new ActivInk(R) PV2400 donor and NV2400 acceptor materials. These results significantly improve upon previously reported records of less than 3% for fully-polymeric cells. The device performance was certified by Newport Corporation’s PV Cell Lab. The results are important for demonstrating the potential of eliminating traditionally used fullerene-based acceptor materials, which have several drawbacks including high cost, difficulty in production scaling, morphology instabilities and poor light absorption
