High efficiency dye sensitized solar cell treated with terminal double-bond based ionic layer which reacted with I2 |
| 초록 |
The new terminal double-bond based ionic layer is introduced in TiO2 electrode surfaces using 3,4,5-tris-butenyloxy benzoic acid. This ionic layer which reacted with electrolyte increases the neutralization of dye as well as decreases the recombination of electrons. These phenomena are revealed by transient absorption spectroscopy and electrochemical impedance spectroscopy. The optimized dye sensitized solar cell shows 10.2% efficiency. The terminal double bonds of material are revealed by 1H NMR and contact angle measurements. |
