Improved performance of planar perovskite devices via inclusion of ammonium acid iodide (AAI) derivatives using a two step inter-diffusion process

Abstract

An improved performance of inverted planar perovskite solar cells is achieved by inclusion of ammonium acid iodide (AAI) derivatives into a perovskite precursor solution. The perovskite's morphology improved upon addition of AAI derivatives, and device parameters showed a strong dependence on the increasing number of methylene units. Enhancement in solar cell efficiency in proportion to the number of methylene units present in AAI derivatives showed a promising development in perovskite photovoltaics.
