Owing to their high-power conversion efficiency (PCE), easy processability, and low fabrication cost, organic lead halide perovskites (OLHP) are emerging as a most promising photovoltaic technology. However, toxicity of lead (Pb) is a major concern for further development. Therefore, it is essential to explore nontoxic metals to replace lead in these materials. In the current research work, nontoxic Mn2+, Na+ and Ba2+ are doped at 1, 5 and 10% mole concentrations to partially substitute Pb2+ in methyl ammonium lead iodide (CH3NH3PbI3 or MAPbI3) perovskite systems, and the effects …
