Organohalide based perovskites have emerged as an important class of material for solar cell applications.Our perovskites precursors are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap carrier diffusion length and power conversion efficiency of perovskites based solar cells.
