A series of silafluorene-based copolymers, poly[9-(2-ethylhexyl)-9-dodecyl-silafluorene-2,7-diyl-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] (P1), poly[9-(2-ethylhexyl)-9-dodecyl-silafluorene-2,7-diyl-alt-2,5-bis-(thiophene-2-yl)thiazolo [5,4-d]thiazole] (P2), and poly[9-(2-ethylhexyl)-9-dodecyl-silafluorene-2,7-diyl-alt-5,5-(5',8'-di-2-thienyl-2,3-bis(4-octyloxyl)phenyl)quinoxaline] (P3), were synthesized and used as donor materials in polymer solar cells (PSCs). The optical, electrochemical, and photovoltaic properties of the copolymers were investigated. The results indicate that
