Outline of Annual Research Achievements

In this research, we developed a novel designed dye-sensitized solar cell using ZnO nanostructures as photoanodes. This advanced technique includes three parties: 1) fabrication of ZnO related thin films. The deposition parameters were optimized, and the conductive and low-cost ITO substrates were synthesized.2) The novel multiple-annealing process was developed, the high-alignment, high transparency, and high stability of ZnO nanostructures were achieved at the low temperature. 3) The morphology of ZnO nanorods was successfully modified by the mist CVD method, the large area and controllable ZnO nanorods were achieved. Finally the dye-sensitized solar cell was demonstrated using both ZnO nanorods and the TiO2 coated ZnO as photoanodes. The overall conversion efficiency of 5.48% was achieved.
According the target in the beginning of the research, we successfully achieved the following results: the large area ZnO nanostructures were fabricated resulting in the high efficiency absorption of dye. The low cost and simple process mist CVD technique was successfully used as coating and modification of ZnO nanostructures. The dye-sensitized solar cell fabrication method was optimized and the highest efficiency using ZnO nanorods as photoanodes was achieved.
This research supplied the new ideal and technique to fabricate the environment friendly solar cell, with the low cost and easy process. With improving the synthesis fabrication, the conversion efficiency of solar cells is expected to significantly improved and high potentially for industrial application in the future.
