Title: Effect of substrate temperature on the facing target sputter deposited TiO{sub 2} photoelectrode of dye-sensitized solar cells

Abstract

Nanocrystalline TiO{sub 2} photoelectrodes were successfully deposited on SnO{sub 2}:F coated glass substrate by facing target reactive sputtering technique with different substrate temperatures ranging from room temperature to 400 deg. C. Low cost chlorophylline based dye was used along with carbon paste on SnO{sub 2}:F glass as a counterelectrode. All the TiO{sub 2} electrodes show good crystallinity. It has been observed that increase of substrate temperature not only alters the ratio of anatase and rutile phase but it also markedly changes the crystal orientation. The amount of dye incorporation was found to be highly dependent on the microstructure of electrodes, as apparent from optical measurements. The dye-sensitized solar cells, comprised of TiO{sub 2} photoelectrode, deposited at substrate temperature of 200 deg. C, show maximum photoelectric conversion efficiency; however, further enhancement of sputtering temperature drastically reduces the efficiency. The variation of photoelectric conversion efficiency of the solar cells with TiO{sub 2} electrodes deposited at different substrate temperatures is discussed with the analysis of different microstructures of the TiO{sub 2} photoelectrodes and the corresponding dye incorporation. Moreover, all the dye-sensitized solar cells of this present investigation exhibit reasonably good fill factor value.
