Abstract All solution-processed semi-transparent perovskite solar cells (PSCs) with high efficiency were fabricated with Ag nanowire (AgNW) top electrode directly coated on the organic electron transport layer (ETL). A unique AgNW/ETL interface morphology was attained by the fabrication of the AgNW-C60 composite electrode through a sequential spin-coating method. The C60 filler spin-coated on the AgNW network engendered a high contact area and favourable energy level alignment at the interface between the ETL and AgNW. As a result, devices based on AgNW-C60 electrode far outperformed devices with pristine AgNW electrodes. By adjusting the thickness of the AgNW film, the AgNW-C60 devices attained a PCE of 11.02%. The incorporation of C60 into the AgNW electrode also led to remarkable stability improvement. The low-temperature solution-processed and semi-transparent AgNW-C60 top electrode is also applicable to other PSC structures with various interfacial layers, thus showing a promising path towards fully-printable, flexible and translucent photovoltaic devices.

一种用于高效半透明钙钛矿太阳能电池的溶液处理的Ag纳米线/C60复合顶部电极

摘要 所有溶液加工的高效半透明钙钛矿太阳能电池（PSC）均采用直接涂覆在有机电子传输层（ETL）上的银纳米线（AgNW）顶部电极制造。通过连续旋涂方法制造 AgNW-C60 复合电极，获得了独特的 AgNW/ETL 界面形​​态。旋涂在 AgNW 网络上的 C60 填料在 ETL 和 AgNW 之间的界面处产生了高接触面积和有利的能级对齐。因此，基于 AgNW-C60 电极的器件的性能远远优于具有原始 AgNW 电极的器件。通过调整 AgNW 薄膜的厚度，AgNW-C60 器件获得了 11.02% 的 PCE。将 C60 掺入 AgNW 电极也显着提高了稳定性。
