We have developed dye-sensitized solar cells (DSCs) for energy harvesting, which specialize in operation in low light environments such as an indoor and a shady places. Our outdoor operation test results showed the DSC generates power with high conversion efficiency especially in the morning, evening and a cloudy day, when light is low or scattered. Regarding our new indoor-type DSC, the leakage current amount was successfully decreased by modifications including the addition of agents to fill the gap between dies on Ti02 nanoparticles and prevent charge recombination. The improved DSC showed superior performance to conventional solar cells under indoor light. We combined the DSC with a DC-DC converter and a capacitor and used it as a power source for a multi-sensor node with various sensors. The node operated continuously even in night time and weekend without light irradiation. That proved the DSC technology is applicable to power generation for energy harvesting devices.
