PS/Ox/FTO junction J-V characteristic. The current-voltage characteristics of PS/Ox/FTO heterojunctions with different light intensities (light intensity increases in the arrow direction) ranging from dark to 110 mW/cm2. Inset in (a) shows a detail of reverse bias region, and (b) shows the schematic configuration (sandwich type) of layers in the heterojunction.
