Evaluation Methods of Energy-Storable Dye-Sensitized Solar Cells

Abstract:

Energy-storable dye-sensitized solar cell (ES-DSSC), which possesses a unique three-electrode system composed of a photoanode, a counter electrode and a charge-storage electrode, is a practical solar rechargeable battery. The ES-DSSC is able to yield output power even in the dark after photocharging and suppress the fluctuation of the output power under the capricious solar irradiation. In this study, the evaluation methods of the ES-DSSC performances were investigated toward their practical use under various illumination conditions. The ES-DSSCs were found to be able to work even under low light intensity. Unlike conventional DSSC array, the ES-DSSC array coupled in a series connection gave a stable output voltage when one of the cells or both cells were shadowed.
