Dithieno[3,2-b:2’,3’-d]arsole-containing conjugated polymers in organic photovoltaic devices
2019
Arsole-derived conjugated polymers are a relatively new class of materials in the field of organic electronics. Herein, we report the synthesis of two new donor polymers containing fused dithieno[3,2-b:2’,3’-d]arsole units and report their application in bulk heterojunction solar cells for the first time. Devices based upon blends with PC71BM display high open circuit voltages around 0.9V and demonstrate power conversion efficiencies around 4%.
