Introduction of cadmium chloride additive to improve the performance and stability of perovskite solar cells.

With the increase in the importance of using green energy sources to meet the world's energy demands, attempts have been made to push perovskite solar cell technology toward industrialization all around the world. Improving the properties of perovskite materials as the heart of PSCs is one of the methods to fabricate favorable photovoltaic (PV) solar cells based on perovskites. Here, cadmium chloride (CdCl) was used as an additive source for the perovskite precursor to improve its PV properties.
