Abstract
Abstract Perovskite solar cells (PSCs) are a great promise to solve the problem of energy demand. However, one of the most important factors to obtain higher yields of high efficiency photovoltaic devices is to produce high quality methyl ammonium lead iodide (MAPbI3) films. In this work, strategies such as solvent engineering, Lewis adduction formation and the incorporation of Imidazolium cation (Im+) were implemented to improve the microstructural quality of the films. The mixed MA99ImI1 film displayed a more homogeneous microstructure compared to the original MAPbI3 film, as well as an improved power conversion efficiency, with a value of 17%.
