Solar cells based on organic-inorganic perovskite materials have dramatically developed in just a short period of time because of efficient light absorption and their unique semiconducting nature. The best power conversion efficiency is continuously recorded via various approaches; devices from sensitized mesoporous structures to planar structures, modified composition of perovskite, and fabrication methods. Despite the amazing improvement, many groups have encountered low reproducibility and lower device efficiency than reported results because of the perovskite's own instability and sensitivity under ambient conditions; thus, we need a realistic and experimental investigation. In this study, we compare solution processing representative fabrication methods, which influence the growth, crystal orientation, and the electronic properties of CH3NH3PbI3, device reproducibility, and efficiency in planar perovskite solar. This comparative study gives a realistic overview of the fabrication methods for planar perovskite solar cells. (C) 2016 Published by Elsevier Ltd.
