摘要: Considering the remarkable progress in photovoltaic performance, scholars have focused on perovskite solar cells (PSCs) over recent two years. TiO2 thin film is a semiconductor with wide band gap and usually used as an electron-selective layer (ESL) PSCs. Although SnO2 exhibits conductivity higher than that of TiO2, its use compact ESL PSCs has not been reported. In this study, nanocrystalline was prepared through sol–gel method then characterized. The composed small tetragonal rutile nanocrystals. We applied into compared their performance based layer. SnO2-ESL-based (S-PSCs) showed short-circuit current density lower open-circuit voltage, fill factor, conversion efficiency conventional TiO2-ESL-based Furthermore, S-PSCs highly dependent measurement means, relationship investigated ...
