Abstract

Dye-sensitized Solar Cell (DSC) is a new type of solar cell by using photocatalytic properties of $TiO_2$. The electric potential distribution in DSCs has played a major role in the operation of such cells. $TiO_2$ thin films were deposited on the ITO substrate by Nd:YAG Pulsed Laser Deposition(PLD) at room temperature and post-deposition annealing at $500^{\circ}C$ in flowing $O_2$ atmosphere for 1hour. The structural properties of $TiO_2$ thin films have investigated by X-ray diffraction(XRD). We manufactured DSC unit cells then I-V and efficiency were tested by solar simulator.
