Polymeric solar cells (PSCs) have attracted considerable attention for their great advantages over existing inorganic solar cells, such as ease of processing, light weight, flexibility, low cost, and so forth. New type for OPVs is D-A polymers which have two absorption band in UV-vis absorption spectra. These UV absorption bands can cover large area of solar spectrum. Recently, derivatives of PCPDTBT were synthesized and reported high photovoltaic properties. We designed and synthesized new acceptor material for D-A polymers. Novel conjugated polymer, Poly(N-9’-heptadecanyl-2,7-carbazole-co-5,5-(4’,7’-di-2-thienyl-2,2-(1,5-pentamethylene)-2H-benzimidazole)) (PCDTPMBI), was synthesized by Stille coupling. The Power conversion effciciency is about 0.2%. |
