摘要
Solvent additives have been widely used to improve the performance of polymer:fullerene derivative based solar cells by controlling morphology and achieving phase separation.In our work, we demonstrated that the most commonly used solvent additive DIO may play different role in different types of polymer solar cells.We fabricated P3HT:PC_(61)BM based solar cell and PTB7-Th:PC_(71)BM solar cell without and with different amount of DIO, which containing 0%-10%.Our results indicated that in the case of P3HT:PC_(61)BM, DIO only act as the high boring point solvent additive to improve the morphology and the higher crystallinity help the device achieved power conversion efficiencies of 3.6%.But in the case of PTB7-Th:PC_(71)BM, DIO will cause PTB7-Th disintegrate and with the amount of DIO and the exposure time under light.
