Abstract

Organic-inorganic trihalide, ABX3 perovskite are excellent candidates for advanced optoelectronic applications beyond photovoltaics. Perovskite single crystals offer several advantageous special features, such as a long diffusion length, low trapped carrier density, and outstanding environmental stability to use in optoelectronics. In this work, Zn has been incorporated into MAPbBr3 single crystals as Zn- Porphyrin to passivate the bulk crystals and enhance their optical and electrical properties. The inverse temperature crystallization phenomenon was used to crystallize MAPbBr3 rapidly in hot solutions. The structural and optical characterization confirms that the passivation enhanced the optoelectronic properties of the single crystals.
