Effect of Anti-Reflective Layer in Dye-Sensitized Solar Cells

Abstract

Anti-reflective (AR) layers play an important role in boosting the amount of light entering a device and reducing reflection losses in a device, thereby enhancing the power conversion efficiency of solar cells. We have coated an AR layer on the surface of a dye-sensitized solar cell device by using an electron beam evaporation system and investigated the effects of the AR layer by measuring photovoltaic performance. The AR layer is found to increases the Jsc and η of the solar cell.
