Potential replacement to lead: Alkali metal potassium and transition metal zinc in organo-metal halide perovskite materials

摘要: Abstract Following the plenty of research work on solving issue popular and promising perovskite solar cells, this article is focused methylammonium lead iodide (MAPbI3) alternative element which can perform as efficiently does. Here, not only different concentrations substitute are investigated, but also higher stable introduced well. Several characterization techniques used to assure validity results. The large alkali metal potassium (K) transition zinc (Zn) studied side by side. results interesting when 5% concentration KI alloyed MAPbI3 shows considerable transport properties like 54 nm diffusion length, 245 × 10−9 Sm−1 photoconductivity, significant majority minority carrier mobility–lifetime product compared it becomes more after 60 days aged ZnCl2 turns into a leading showing high stability among all. morphology investigations show both materials achieve islands desired in
