摘　　要：In comparison with inorganic solar cells, polymer solar cells （PSCs） possess the advantages of light weight and po- tential low-cost production technology such as roll-to-roll printing production. And the power conversion efficiency （PCE） of the PSCs reached ca. 10% recently. However, the high PCE is limited to the PSCs with the low bandgap pol- ymer PBDTTTs as donor and PCTOBM as acceptor, and the optimized active layer thickness of the high efficiency PSCs is usually less than 100 nm. The dominant acceptor of PCTOBM places serious limitation on the development of the polymer donor materials to match with PC70BM, and the thin active layer makes large area fabrication of the PSCs very difficult.In comparison with inorganic solar cells,polymer solar cells(PSCs)possess the advantages of light weight and potential low-cost production technology such as roll-to-roll printing production.And the power conversion efficiency(PCE)of the PSCs reached ca.10%recently.However,the high PCE is limited to the PSCs with the low bandgap polymer PBDTTTs as donor and PC70BM as acceptor,and
