Application

Monomer for synthesis of polymers for high power conversion efficiency (PCE) organic solar cells and OFETs through direct arylation polycondensation. Inverted bulk heterojunction solar cells based on PolyDTS-TPD:PC70BM blends or PolyDTG-TPD:PC70BM blends achieved average power conversion efficiencies of from 6.6 - 7.3%. (DTS: dithienosilole; DTG: dithienogermole; TPD: thienopyrrolodione)

We report the synthesis and bulk heterojunction photovoltaic performance of the first dithienogermole (DTG)-containing conjugated polymer. Stille polycondensation of a distannyl-DTG derivative with 1,3-dibromo-N-octyl-thienopyrrolodione (TPD) results in an alternating copolymer which displays light absorption extending to 735 nm, and a
