Abstract

Controlling the morphology of the active layer in organic solar cells (OSCs) is challenging. Now, acenaphthene is shown to induce the two-step crystallization of non-fullerene acceptors to achieve a highly oriented arrangement. The resulting improvement in the charge transport properties enables a binary OSC with 21% efficiency and a 83.2% fill factor.

通过两步结晶工艺提高二元有机太阳能电池的效率

控制有机太阳能电池（OSCs）活性层的形态是一个具有挑战性的问题。现在，苊被证明可以诱导非富勒烯受体的两步结晶，以实现高度定向的排列。由此产生的电荷输运特性的改善使二元OSC具有21%的效率和83.2%的填充因子。
