Abstract
Perovskite solar cells (PSCs) are a novel emerging technology that are the third generation of solar cells, following wafer-based and thin-film-based predecessors. Solar photovoltaic (PV) technology that uses perovskite materials has a significant advantage over conventional solar PV, as it can respond to various light wavelengths and increase the amount of sunlight converted to electricity. In addition, PSCs are flexible, semi-transparent, customizable, lightweight, and have a high power conversion efficiency (PCE). Through the use of dual-graded light absorber/active layers, and double perovskite lead-free material Cs
