High Efficiency Dye-Sensitized Solar Cell

Abstract

Solar cell is recognized as clean energy. Si type of the solar cell dominated the market of solar cell because of high efficiency. On the other hand, dye-sensitized solar cell (DSC) had good merits those were flexibility, colorful, cost and installation location in spite of the low efficiency. Most researchers focused on materials of DSC and relatively improved the efficiency. We focused on the fabrication process of DSC for improving the efficiency. We applied the micro 3D printer for fabrication of titania layer to control the thickness and porous ratio in the titania layer.
