Polymer solar cell (PSC) has great spectrum matching with the room lights and PSC has great photovoltaic performance under the low to high illuminance compared to other types of solar cells. So, we fabricate the PSC module for the indoor use and investigate the electrical characteristics under the various light sources. The PSC photovoltaic performance is 43.5µW/cm2 under the fluorescent light 1000lux (0.1mW/cm2) and PCE=6.0% under the sunlight (1SUN-100mW/cm2).

This PSC module has practical durability and stability against the heat and light exposure. So, PSC is used as the self-charging batteries for mobile devices and wireless sensor networks.
