摘要：

Although flexible perovskite solar cells have made extensive progress, there is a lack of investigation on the performance of flexible perovskite solar cells under bending state. Here, two-dimensional models of flexible perovskite solar cells have been performed to reveal the effect of bending angles and directions for the first time. Simulated results are in good agreement with experimentally reported data, validating the accuracy of our model. To optimize mechanical and optical performance under bending state, silica subwavelength array is embedded on the surface of the flexible substrate. Hence, the current density of flexible perovskite solar cells has been improved by 7.3% at downwards bending 60 and 1.9% at upwards bending 60. Our work provides a guide for the design of efficient flexible perovskite solar cells under bending state.
