Surface Passivation of MAPbBr3 Perovskite Single Crystals to Suppress Ion Migration and Enhance Photoelectronic Performance
L Chen, H Wang, W Zhang, F Li, Z Wang… - … Applied Materials & …, 2022 - ACS Publications
Recently, organometal halide perovskites (OHPs) have achieved significant advancement in
photovoltaics, light-emitting diodes, X-ray detectors, and transistors. However,
commercialization and practical applications were hindered by the notorious ion migration
issue of OHPs. Here, we report a simple solvent-based surface passivation strategy with
organic halide salts (methylammonium bromide (MABr) and phenylethylammonium bromide
(PEABr)) to suppress the ion migration of MAPbBr3 single crystals. The surface passivation …
