Reproducible formation of uniform CH sub(3)NH sub(3)PbI sub(3-x)Cl sub(x) mixed halide perovskite film by separation of the powder formation and spin-coating process

To deposit uniform CH sub(3)NH sub(3)PbI sub(3-x)Cl sub(x) (MAPbI sub(3-x)Cl sub(x)) mixed halide perovskite film reproducibly, we separated the conventional process to formation of MAPbI sub(3-x)Cl sub(x) mixed halide perovskite powder by heat-treatment process and deposition of MAPbI sub(3-x)Cl su...

Description
Summary:To deposit uniform CH sub(3)NH sub(3)PbI sub(3-x)Cl sub(x) (MAPbI sub(3-x)Cl sub(x)) mixed halide perovskite film reproducibly, we separated the conventional process to formation of MAPbI sub(3-x)Cl sub(x) mixed halide perovskite powder by heat-treatment process and deposition of MAPbI sub(3-x)Cl sub(x) mixed halide perovskite film by single step spin-coating. The deviation of power conversion efficiency of MAPbI sub(3-x)Cl sub(x) mixed halide perovskite solar cells prepared by currently proposed method and conventional method was 13.75 plus or minus 0.88% and 8.02 plus or minus 1.65%, respectively, because more uniform MAPbI sub(3-x)Cl sub(x) mixed halide perovskite film could be reproducibly formed by separating the formation process of mixed halide perovskite powder and the single step spin-coating process.
