Justifying benzoselenadiazole acceptor core as organic semiconductor for stable bulk-heterojunction organic solar cells at ambient temperature
This work describes the utilization of D-A-D type organic semiconductor, 4,4’-(benzo[c] [1,2,5]selenadiazole-4,7-diyl)bis(N,N-diphenylaniline), denoted as Se-2TPA, containing benzoselenadiazole (BSe) as acceptor core and end-capped with triphenylamine (TPA) donor units as donor materials in solar ce...
