Synthesis and stability of Cs-rich α phase Cs1-xDMAxPbI2Br(0 ≤ x ≤ 0.3) perovskite film
In this study, we successfully synthesized α-phase Cs1-xDMAxPbI2Br(0 ≤ x ≤ 0.3) without impurity and conducted device performance research and stability testing on it. The champion photoelectric conversion efficiency of α phase Cs0.8DMA0.2PbI2Br in inverted perovskite solar cells is 8.24 %. Compared with pure CsPbI2Br without DMA+, humidity stability of α-Cs0.8DMA0.2PbI2Br has been improved and it also maintains thermal and ultraviolet stability. This strategy shows bright application prospect for improving the stability of CsPbI2Br perovskite solar cells.
