Application

Lead bromide finds application in synthesis of perovksites based photovoltaic materials. Our perovskite grade PbBr2 can readily be dissolved in DMF: DMSO (1:1) to yield 1M solution.
Lead(II) Bromide is a key component in the fabrication of the perovskite absorber layer in perovskite solar cells. It is commonly combined with other metal halides, such as methylammonium lead triiodide (MAPbI3), to form the perovskite structure. The high purity level and trace metal basis of the material contribute to the efficiency and stability of the resulting solar cells.

Metal-halide perovskites are crystalline materials originally developed out of scientific curiosity. Unexpectedly, solar cells incorporating these perovskites are rapidly emerging as serious contenders to rival the leading photovoltaic technologies. Power conversion efficiencies have jumped from 3% to over 20% in
