Inorganic cesium lead mixed halide based perovskite solar materials modified with functional silver iodide.

ABSTRACT: Inorganic CsPbIBr₂ perovskites have recently attracted enormous attention as a viable alternative material for optoelectronic applications due to their higher efficiency, thermal stability, suitable bandgap, and proper optical absorption. However, the CsPbIBr₂ perovskite films fabricated using a one-step deposition technique is usually comprised of small grain size with a large number of grain boundaries and compositional defects. In this work, silver iodide (AgI) will be incorporated as an additive into the CsPbIBr₂ perovskite precursor solution to prepare the unique perovskite CsI(PbBr₂)_1-x(AgI)_x. The AgI additive in the precursor solution works as a nucleation promoter which will help the perovskite to grow and merge into
