The solution processing of pinhole-free methylammonium lead triiodide perovskite-C fullerene (MAPbI :C ) blend films on fluorine-doped tin oxide (FTO)-coated glass substrates is presented. Based on this approach, a simplified and robust protocol for the preparation of efficient electron-transport layer (ETL)-free perovskite solar cells is described. Power conversion efficiency (PCE) of 13.6 % under AM 1.5 G simulated sunlight is demonstrated for these devices. Comparative impedance spectroscopy and photostability analysis of the MAPbI :C and single MAPbI films compared with conventional compact TiO ETL-based devices are shown. The beneficial impact of using MAPbI :C blend films is emphasized.
介绍了在氟掺杂氧化锡（FTO）涂层玻璃基板上制备无针孔甲脒铅三碘化物钙钛矿 - C富勒烯（MAPbI₃:C₆₀）混合薄膜的溶液处理方法。基于此方法，描述了一种用于制备高效无电子传输层（ETL）钙钛矿太阳能电池的简化且稳健的方案。这些器件在AM 1.5 G模拟太阳光下的功率转换效率（PCE）为13.6%。展示了与传统基于致密TiO₂ ETL的器件相比，MAPbI₃:C₆₀和单一MAPbI₃薄膜的比较阻抗谱和光稳定性分析。强调了使用MAPbI₃:C₆₀混合薄膜的有益影响。
