Solution‐processed organic photovoltaic devices containing p‐type and non‐fullerene n‐type small molecules obtain power conversion efficiencies as high as 2.4%. The optoelectronic properties of the n‐type material BT(TTI‐n12)2 allow these devices to display high open‐circuit voltages (>0.85 V) and generate significant charge carriers through hole transfer in addition to the electron‐transfer pathway, which is
含有p型和非富勒烯n型小分子的溶液处理有机光伏器件的功率转换效率高达2.4%。n型材料BT(TTI- n 12)2的光电特性使这些器件能够显示高开路电压(> 0.85 V),并通过空穴转移以及电子转移途径产生大量的电荷载流子,这在基于富勒烯的设备中很常见。
