In this research, ZnO nanoparticles were synthesized by spray-pyrolysis method using the zinc acetate dihydrate as starting material at synthesis temperature of 900°C with various concentrations (0.01, 0.1, 1.0 M, respectively). The physico-chemical property of synthesized ZnO nanoparticles was characterized by XRD, SEM, FT-IR, and UV-vis spectroscopy. The synthesized ZnO nanoparticles indicated particle size with two-type shape. With increased precursor concentration, the ZnO nanoparticles were

Abstract Over the past number of years, the power conversion efficiency of perovskite solar cells has remained at 25.5%, reflecting a respectable result for the general incorporation of organometallic trihalide perovskite solar cells. However, perovskite solar cells still suffer from long-term stability issues. Perovskite decomposes upon exposure to moisture, thermal, and UV-A light. Studies related to this context have remained ongoing. Recently, research was mainly conducted on the stability o
