Increased dye-loading amount by electrostatic interaction between metal-cation adsorbed ZnO and N719 dye |
| 초록 |
The power conversion efficiencies of ZnO-based solar cells are considerably lower than those reported for TiO2. It is because Zn2+/dye complex is formed during prolonged sensitization process, and it lowers the electron injection efficiency from excited dye to ZnO. Thus, it is necessary to increase dye-adsorption amount in a short time. In this study, we investigated amount of dye-adsorption on metal-cation adsorbed ZnO surface. ZnO nanorods were soaked into aqueous solutions containing metal cations to produce positively charged ZnO surface, and then they were dipped into the dye solution to load dyes. As a result, dye-loading amount was increased by electrostatic interaction between positively charged ZnO and negatively charged dye, compared to that of the simple dipping process. |
