Flexible perovskite solar cells (FPSCs) have attracted enormous interest in wearable and portable electronics due to their high power-per-weight and low cost. Flexible and efficient perovskite solar cells require the development of flexible electrodes compatible with the optoelectronic properties of perovskite. In this review, the recent progress of flexible electrodes used in FPSCs is comprehensively reviewed. The major features of flexible transparent electrodes, including transparent conductive oxides, conductive polymer, carbon nanomaterials and nanostructured metallic materials are systematically compared. And the corresponding modification strategies and device performance are summarized. Moreover, flexible opaque electrodes including metal films, opaque carbon materials and metal foils are critically assessed. Finally, the development directions and difficulties of flexible electrodes are given.
柔性钙钛矿太阳能电池（FPSC）因其高功率重量比和低成本，在可穿戴和便携式电子设备中引起了极大的关注。柔性且高效的钙钛矿太阳能电池需要开发与钙钛矿的光电特性相兼容的柔性电极。在本综述中，全面回顾了用于FPSC的柔性电极的最新进展。系统地比较了柔性透明电极的主要特性，包括透明导电氧化物、导电聚合物、碳纳米材料和纳米结构金属材料。并总结了相应的改性策略和器件性能。此外，还对包括金属薄膜、不透明碳材料和金属箔在内的柔性不透明电极进行了批判性评估。最后，给出了柔性电极的发展方向和面临的困难。
