Synergetic effects of DMA cation doping and Cl anion additives induced re-growth of MA1−xDMAxPbI3 perovskites

Abstract

The simultaneous improvement of photovoltaic performance and stability is crucial for further commercial development of MAPbI3 perovskites. Here we report a dual-ion exchange and alloying method using DMACl (dimethylammonium chloride) to improve the stability and charge transport ability. The synergetic effect of the DMA cation and Cl anion induces the re-growth of perovskite crystals and forms cubic phase MA1−xDMAxPbI3. As a result, the efficiency and stability of DMACl-based MAPbI3 perovskite solar cells are significantly improved. Such dual-function of DMA cation doping and the Cl anion additive provides an effective strategy for the control of MAPbI3 perovskite crystallization.
