An Unconventional Approach for Improving the Efficiency of Conventional DSSCs by Integrating Carbonized TiO2 Thin Layers |
| 초록 |
Recently, unconventional approaches for enhancing solar cell performance have gained tremendous interest. An increase in the charge carrier generation can be achieved by introducing novel materials such as metal nanoparticles, periodic nanostructures, and carbon structures into conventional solar cells. In particular, various types of carbon materials including nanotubes, nanofibers, and graphene have been used to ensure high electrical conductivity, which is essential for increasing the electron collections in solar cells. In this study, we introduce a distinctly different strategy to integrate carbonized TiO2 thin layers into conventional TiO2-based DSSCs. Ordered arrays of TiO2 dots in carbon matrix were fabricated via calcining UV-stabilized PS-b-P4VP/TiO2 sol-gel film and integrated into both sides of pristine TiO2 layer. An increase of 57.2 % in overall power conversion efficiency was obtained compared with neat TiO2-based DSSCs. |
