crystallization process, which is highly susceptible to environmental conditions, the film quality of perovskite on different planar substrates exhibits large difference under varied deposition conditions. In addition, the electronic and physical nature of the internal heterojunctions within the perovskite solar cells are also important and require careful control and optimization for efficient and reproducible devices. Presently, many researchers in different laboratories still experience poor reproducibility of devices when they follow the reported experimental procedural descriptions in the literature, which hinders and slows the global progress of perovskite solar cells research. Therefore, it is essential to have a detailed and high-reproducible methodology for the fabrication of efficient planar perovskite solar cells. If a standard and reproducible cell” existed, it would also make fair comparison “control between different progress in different laboratories easier. In this paper, we present detailed procedures for the fabrication of reproducible planar perovskite solar cells (n-i-p and p-i-n structures) based on one-step coating process. We use the benchmark MAPbI3(Cl) perovskites fabricated from precursors composed of methylammonium iodide (MAI) and two different lead metal sources including lead chloride (PbCl2) or lead acetate trihydrate (Pb(Ac)2·3H2O) as the example to discuss key parameters for the fabrication of high-quality perovskite films. In addition, we point out and discuss the key processes affecting the device performance of perovskite solar cells and our optimization strategy. We provide detailed information about the reagents, equipment and deposition parameters for PbCl2 and Pb(Ac)2·3H2O routes developed in our lab. We believe that this methods paper will be a useful guideline for the community to fabricate high-reproducible perovskite films and efficient planar solar cells based on one-step solution processed MAPbI3 perovskites. Conventional n-i-p perovskite solar cells fabricated from 3:1 MAI:PbCl2 precursor The embodiments of perovskite employed as light harvester in solar cells were fabricated
