TiO2 photoelectrode structure with gradations in W concentration for DSSC application |
| 초록 |
The transportation of photo-generated electron in dye sensitized solar cells (DSSCs) is one of the most important criteria to enhance their overall power conversion efficiency. The photo-generated electron is injected from the lowest unoccupied molecular orbital of photosensitizer into the conduction band level of TiO2, and then transferred to the conductive transparent electrode. In this work, W-doped TiO2 is introduced as blocking layer with various amount of tungsten dopant. W-doped TiO2 blocking layers are deposited on transparent electrode by spin coating. W-doping leads to increase the short circuit current density due to the enhancement of charge transport rate. However, it causes the decrease in the open circuit voltage because the probability of charge recombination tends to increase with the increase in the amount of W dopant. |
