Optimization of Mo-doped TiO2 Photo-electrode to enhance the Photovoltaic Performance in Dye-sensitized Solar Cells |
| 초록 |
The metal-doped TiO2 blocking layer in the mesoporous TiO2 network of dye-sensitized solar cells (DSSCs) is suggested to enhance the power conversion efficiency. DSSCs based on Mo-TiO2 blocking layer enhances the charge transport in the photoanode, because the downward shifted conduction band and increased charge transport, the photocurrent density (Jsc) of the devices are improved remarkably with an almost unchanged photovoltage. We believe that the electron diffusion length on the TiO2 network in photo-electrode is not sufficient to reach the thoretical maximum efficiency of DSSC and thus, doping of metal into TiO2 blocking layer can enhance the electron correcting efficiency in the photo-electrode in DSSC. |
