Tin Based Perovskite Solar Cells

Moreover tinlead mixed perovskites that contain less lead than conventional perovskites for high-performance PSCs and tandem solar cells are discussed. However the crystallization process of tin-based perovskite is too fast during the solution-deposited process resulting in abundant pinholes and poor homogeneity that cause serious charge recombination in perovskite layer.
