Application

Calcium iodide can be used:
  • As a passivator of CH3NH3PbI3(MAPbI3) perovskite films to achieve high efficiency and long-term stability.
  • As a dopant to prepare 3D γ-CsPbI3 perovskite solar cells, to improve their stability and power conversion efficiency.
  • As a precursor to synthesize a series of heteroleptic calcium formamidinate derivatives.
  • As a catalyst for photooxidative oxylactonization of oxocarboxylic acids.
