عنوان انگلیسی Fabrication of Lead Iodide Perovskite Solar Cells by Incorporating Cr-substituted and Pristine Ba2In2O5•(H2O)x as Additives
چکیده انگلیسی مقاله In this study, two inorganic additives with perovskite structure have been used as additives in fabrication of perovskite solar cells (PSCs). Ba2In2O5·(H2O)x and Ba2(In1.8Cr0.2)O5·(H2O)y was applied in perovskite precursor solution for synthesis of photo absorption layer in PCSs by a one-step solution method with solvent engineering technique. Cr-substituted and pristine Ba2In2O5·(H2O)x were prepared by solid-state and soft chemistry methods like the procedures in previous work, and utilized to improve the crystal structure and morphology of perovskite layer of PSCs. The morphology of the new perovskite layers was studied by FE-SEM, and XRD analysis. The results showed using 2 wt % of additives in precursor solution of fabricated PCSs increased the open-circuit voltage (Voc) of cells, also the power-conversion efficiency of the cells improved from 7.8 % to 9.7, and 9.3 % by using both additives respectively. Cr-substituted and pristine Ba2In2O5·(H2O)x could modify the coverage of perovskite film on the TiO2 layer and consequently improve the photovoltaic stability and performance of perovskite solar cells.
