Application of TiO2 nanotubes in Dye sensitized solar cells |
| 초록 |
In recent years, the depletion of fossil fuels has become one of the big challenges that people are currently facing. Dye sensitized solar cells (DSSCs) which converts solar light into electric energy, is expected to be a potential solution for energy problems. In this work, DSSC which is composed single layer (TiO2-P25 or TiO2 nanotubes) and double layer fabricated. In the double layer DSSC structure, the under-layer was TiO2-P25 film, and the top layer consisted of a mixture of TiO2-P25 and TiO2 nanotubes. The results indicated that the efficiency of the DSSC with the double layer structure was a significant improvement in comparison to the DSSC consisting of only a single film layer. The addition of TiO2-P25 in the top layer caused an improvement in the adsorption of dye molecules on the film rather than on the TiO2 nanotubes only. The presence of the TiO2 nanotubes together with TiO2-P25 in the top layer revealed the enhancement in harvesting the incident light and an improvement of electron transport through the film. |
