摘要
High boiling point solvent additive, employed during the solution processing of active layer fabrications, impact the efficiency of bulk heterojunction(BHJ) polymer solar cells(PSC) by influencing the morphological of the active layer.The photovoltaic performances of the PSCs based on the donor of PTB7 and the acceptor of PC_(71)BM was optimized by using 5 vol % high-boiling-point solvent additive of 2-Bromonaphthalene(BN).The optimized air-processed PSC based on PTB7:PC_(71)BM(1:1.5 w/w) with 5 vol % BN exhibited a power conversion efficiency(PCE) of 7.01 % with open-circuit voltage(V_(oc)) of 0.731 V, short-circuit current density(J_(sc)) of 13.79 mA cm~(-2), and fill factor(FF) of 69.46 %.Our results indicate that the improved efficiency is due to the optimized PTB7/PC_(71)BM interpenetrating network and the enhanced absorption of the active layer by using the BN as solvent additive.
