Surface passivation of dye-sensitized TiO2 nanoparticles via tetraethyl orthosilicate derivatives in dye-sensitized solar cells |
| 초록 |
Typical dye-sensitized solar cells (DSCs) configure a photoelectrode, electrolyte, and counter electrode. The photoelectrode consists of a conducting substrate for collecting electrons, a semiconductor layer for transporting electrons, and sensitizers for generating electrons. One common way to increase the overall energy conversion efficiency is to minimize the leakage by the electron recombination through the interface between the semiconductor layer and the electrolyte since the generated electrons by the sensitizers are transported through the semiconductor layer. The precedent research has been intensively progressed to retard these recombination reactions and one of them is the use of co-adsorbing molecules. Herein, we introduce tetraethyl orthosilicate (TEOS) derivatives as a co-adsorbent on the semiconductor surface. The electron recombination is evaluated and characterized by photoelectrochemical measurements before and after the co-adsorbing treatment of the TEOS derivatives. |
