The sunlight is a clean, abundant and virtually limitless energy source which can be used to address the growing global energy needs. Recently, polymer photovoltaic cells (PVCs) have received much attention because of their flexibility, facile processibility, low weight and low production cost. However, their relatively large bandgaps limited the short circuit current (Jsc), reducing the PCE. In order to further improve the efficiency, low band gap conjugated polymers were developed to better match the solar spectrum and thereby produce higher Jsc.8,9 Great progress has been made in PVCs based on bulk-heterojunction (BHJ) networks made of low band gap conjugated polymers and fullerene derivatives in the past few years, and efficiency as high as more than 7% has been reported 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%.
