具有340 nm厚的体异质结膜的小带隙聚合物太阳能电池（PSC）表现出9.40%的高功率转换效率，这是由于20.07 mA cm（-2）的高短路电流密度（JSC）和0.70的填充因子。这种显著的效率归因于厚有源层的最大化光吸收和通过加工添加剂优化的横向和垂直形态的最小化复合。
Small-bandgap polymer solar cells (PSCs) with a thick bulk heterojunction film of 340 nm exhibit high power conversion efficiencies of 9.40% resulting from high short-circuit current density (JSC) of 20.07 mA cm (-2) and fill factor of 0.70. This remarkable efficiency is attributed to maximized light absorption by the thick active layer and minimized recombination by the optimized lateral and vertical morphology through the processing additive.
