Dye-Sensitized Solar Cell for Energy Harvesting Applications

A dye-sensitized solar cell (DSC) has unique properties that the cell performance does not readily decrease even at higher incident light angles compared with a Si solar cell and dose not decrease or rather increases under low light conditions. Fujikura is developing new applications of DSC by taking advantages of these properties to the field of “Energy Harvesting” where rapid growth of market has started recently. The results of our outdoor operation tests showed that a DSC generates 1.4 times larger power than a polycrystalline Si solar cell that has the same rated output, when a DSC module is placed on a north wall where the sun light dose not arrive directly. The DSC specially developed for indoor use has twice larger generation performance than amorphous Si solar cells. In this paper we will introduce these technologies of DSC.
