Interfacial modification is crucial for improving the photovoltaic performance. In this work, we present an aminosilane as a molecular linker between the ZnO electron-transport layer and fullerene derivative phenyl-C₇₁-butyric acid methyl ester (PC₇₁BM)-based active layer for efficient inverted polymer solar cells. An enhancement in the power-conversion efficiency (PCE), from 8.47 to 9.46%, was achieved on using PTB7-Th as donors. The aminosilane molecular linker provides dual functionalities for enhanced PCE, including (1) passivating the ZnO surface and decreasing the surface work function of ZnO for energy-level alignment and (2) bonding onto the fullerene derivative PC₇₁BM-based active layer to reduce the interface contact resistance.

氨基硅烷作为高效反型聚合物太阳能电池电子传输层和活性层之间的分子连接基

界面改性对于改善光伏性能至关重要。在这项工作中，我们提出了一种氨基硅烷，作为ZnO电子传输层和富勒烯衍生物苯基-C _71-丁酸甲酯（PC ₇₁ BM）基活性层之间的分子连接体，用于高效倒置聚合物太阳能电池。使用PTB7-Th作为供体，功率转换效率（PCE）从8.47提高到9.46％。氨基硅烷分子接头为增强PCE提供了双重功能，包括（1）钝化ZnO表面并降低ZnO的表面功函数以实现能级对准；以及（2）键合在富勒烯衍生物PC ₇₁ BM基活性层上以减少接口接触电阻。
