Butane-1,4-diammonium iodide is a precursor for the synthesis of perovskite semiconductors in perovskite solar cells. Its addition to the precursor solution has been shown in increasing efficiency and stability of solar cells.', 'Organohalide based perovskites have emerged as an important class of material for solar cell applications. The variations/substitution in organohalide cations and anions is employed for the optimization of the band gap, carrier diffusion length, and power conversion efficiency of perovskites based solar cells. Therefore adding a suite of organohalide precursors would be a good expansion of our Perovskites portfolio.
