Fig. 4From: UV Treatment of Low-Temperature Processed SnO2 Electron Transport Layers for Planar Perovskite Solar CellsJ-V characteristics of the device. The characteristics depend on the different concentrations of SnO2 which are varied from 10 to 30% under AM1.5G illumination of 100 mW/cm2. The inset shows the corresponding PCE-V curveBack to article page
