Synthesized a random terpolymer P2 consist of one donor and three acceptor units. Exhibit optical bandgap of 1.18 eV with broad absorption extended up to 1100 nm. Employed as donor along with PC71BM as acceptor for bulk heterojunction PSCs. PSCs based on blended film processed with DIO/DCB showed PCE of 7.22%.
