Abstract

A new crystallizable low band gap conjugated copolymer BTT ‐ DTFFBT is designed and synthesized. The polymer solar cells based on BTT ‐ DTFFBT: PC71BM photoactive layer are fabricated and characterized. It is found that after combined treatment of 1 vol % 1 ‐ chloronaphthalene (CN) additive and thermal annealing at 180 °C for 10 min, the device shows a power conversion efficiency (PCE) of 5.61% and good thermal stability.
