摘要 | All inorganic perovskite solar cells (PSCs) have been demonstrated to get tremendous interest recently owing to their better thermal stability. Nevertheless, some CsPbI2Br films prepared at low temperature have lower quality compared to those annealing at high temperature. Herein, to obtain high performance PSCs, a simple posttreatment strategy is presented by spin coating acetylacetone (AA) solution on the CsPbI2Br films. The AA treatment can reduce the density traps on the CsPbI2Br films surface and enlarge the size of grains, resulting in enhanced performance PSCs. After optimizing surface treatment, the devices based on low-temperature processed CsPbI2Br with AA treatment achieved a power conversion efficiency (PCE) of 14.43%. The better CsPbI2Br films quality and interface contact of hole transport layer (HTL)/CsPbI2Br result in better device stability. Therefore, it could be a promising post treatment method for enhancing the performance of PSCs by introducing AA on the perovskite surface. |
