Abstract
Photoactivity and surface chemistry properties, including optical density and surface charge transfer characteristic, of a photoanode in a dye-sensitized solar cell (DSSC) play a critical role in the device overall performance. In this study, the role of Ag ions adsorption on the surface of ZnO nanorods on the photoactivity properties was investigated. It was found that the Ag ions attachment onto the ZnO nanorods surface not only modified the surface chemistry but also the photoactivity properties of the ZnO nanorods. The surface chemistry that is indicated by the charge transfer resistance characteristic, improved significantly upon the treatment of ZnO nanarods with Ag ion solution. This produces dramatically enhancement in the DSSC performances. Power conversion efficiency enhancement up to three times higher, namely from 0.46 to 1.12%, has been successfully recorded. The mechanism of the device improvement upon the introduction of Ag ion on the surface of ZnO nanorods will be discussed.
