Study on Optical and Electrical Properties of Thermally Evaporated Tin Oxide Thin Films for Perovskite Solar Cells

Perovskite solar cells were fabricated with SnO<sub>2</sub> thin films as a window layer and electron transport layer by thermal evaporation. Fundamental characteristics of SnO<sub>2</sub> thin films to determine the performance of solar cells were investigated in an optical...
