Design and Parametric Analysis of Tungsten Disulfide Etl Based Perovskite Solar Cell

Enhancing the structural and optoelectronic properties of double ETL nickel-doped CsPbIBr2 perovskite solar cells

“…Doping, the process of introducing impurities into a semiconductor, has been identified as a potentially effective strategy for improving the properties of CsPbIBr 2 perovskites. 9,10 Previous literature indicates that doping can modify the electronic structure, improve the material's stability, and enhance its optoelectronic properties. Tan et al replaced Cs sites with smaller Li + ions to enhance perovskite solar cell PCE to 9.25% based on CsPbIBr 2 .…”
