Progress of High‐Throughput and Low‐Cost Flexible Perovskite Solar Cells

In recent years, the era of perovskites has experienced splendid development. Among perovskites, flexible perovskite solar cells (FPSCs) have received increasing attention due to their high efficiency, light weight, low cost, excellent flexibility, and low‐temperature solution processing ability. In the last decade, the power conversion efficiency of FPSCs has increased significantly from 2.62% to more than 20%. Herein, a succinct overview of the current endeavor to achieve low‐temperature FPSCs is provided. The recent developments, including flexible substrates, transparent conductive electrodes, perovskite absorbers, and device manufacturing methods, are vividly discussed. The strategies for enhancing the stability and flexibility of FPSCs are presented in terms of electrode materials, device encapsulation, and structural effects. Finally, the most encouraging and potential studies for the future of flexible PSCs are revealed.
