Abstract: At present, most of the traditional energy devices are planar rigid structures. Although they are sturdy and durable, it is difficult to meet the requirements of miniaturization, lightweight, flexibility and integration for the wearability of the devices, which is the bottleneck of the current application. Textile materials, as human natural wearable materials, have incomparable flexibility and wearing comfort, and can adapt to human curved surfaces. So, the construction of energy devices based on textile materials is an important direction of wearable technology development. In this paper, the device structure and working principle of perovskite solar cells are introduced, the research progress of flexible perovskite solar cells is also introduced from three aspects: electron transport layer material, hole transport layer material and substrate material, and the latest research work of textile-based flexible perovskite solar cells is reviewed. Finally, the future development of flexible perovskite solar cells, including ones based on textiles, is prospected.
