The objective of this study was to comprehensively investigate and compare PCBM/ZnO and C₆₀/BCP-based electron transport layers (ETLs) (well recognized as representative ETLs) between perovskite and metal electrode in perovskite solar cells (PeSCs) for high-performance p-i-n structure PeSCs. Their film characteristics and their effects on solar cell performances were studied. When PCBM/ZnO was used as ETL material, the PCE of PeSCs was 19.36 %, which was higher than the PCE of 17.10 % when C₆₀/BCP was used possibly due to more efficient charge recombination reduction and charge extraction shown in PCBM/ZnO-based devices. However, in terms of stability (air, light-soaking, and heat), C₆₀/BCP-based devices showed higher stability than PCBM/ZnO-based devices.

本研究的目的是全面研究和比较钙钛矿太阳能电池 (PeSC) 中钙钛矿和金属电极之间基于 PCBM/ZnO 和 C ₆₀ /BCP 的电子传输层 (ETL)（公认的代表性 ETL），以实现高性能引脚结构 PeSCs。研究了它们的薄膜特性及其对太阳能电池性能的影响。当 PCBM/ZnO 用作 ETL 材料时，PeSCs 的 PCE 为 19.36 %，高于使用 C ₆₀ /BCP 时 17.10 % 的 PCE，这可能是由于 PCBM/ZnO 中更有效的电荷复合减少和电荷提取- 基于设备。然而，在稳定性（空气、光浸泡和热）方面，基于 C ₆₀ /BCP 的器件表现出比基于 PCBM/ZnO 的器件更高的稳定性。
