Homogeneous Ag nanowires with optimal growth of (111) crystal face were synthesized by low-cost alcohol-thermal method,and then the Ag nanowires were mixed into the TiO2 paster to prepared the photoanodes for dye-sensitized solar cells with different content of Ag nanowires.The photovoltaic performance of the corresponding solar cells was tested.The results showed that with the increase of Ag nanowire content in the photoanode,the short-circuit current of the battery increased significantly.When the Ag nanowire content reached 2wt%,the short-circuit current of the cell was increased from 4.58mA/cm2 to 7.43mA/cm2,and the photovoltaic conversion efficiency of the solar cell was increased to 3.70%.The increase in short-circuit current was mainly attributed to the presence of Ag nanowires,which provided a direct and fast electron transport channel for dye-sensitized solar cells,which was conducive to electron transfer.The introducing one-dimensional fast electron channel into the photoanode of the cell involved in this study provides a new idea and way for the development of high-performance dye-sensitized solar cells.
