An energy cascading structure is designed in a polymer photovoltaic device to suppress recombination and improve quantum yields. By the insertion of a thin polymer interlayer with intermediate energy levels, electrons and holes can effectively shuttle away from each other while being spatially separated from recombination. An increase in open-circuit voltage and short-circuit current are observed in modified devices.
在聚合物光伏器件中设计了一个能量级联结构，以抑制复合并提高量子产率。通过插入具有中间能级的薄聚合物层，电子和空穴可以在空间分离的同时有效地相互穿梭。在改性器件中观察到开路电压和短路电流的增加。
