Enhancement of dye-sensitized solar cells by using TiO2-Tourmaline powder composites as working electrode |
| 초록 |
We successfully fabricated the TiO2-based photoelectrodes composited with Tourmaline powder to improve the power conversion efficiency of dye-sensitized solar cells(DSSCs). The TiO2-Tourmaline composite electrode has been prepared by a direct mixing method. The ratio of Tourmaline powder was 1~5wt%. This composited electrode were immersed in 0.5mM N719 solution in ethanol for 24h. The results show that the DSSCs incorporation 3wt% tourmaline powder in TiO2 photoelectrode was enhanced upto 20% compared with the pristine TiO2 photoelectrode. We investingated Diffusion coefficient(Dn), Diffusion length(Ln), Recombination life time(τr) from the observation of Intensity Modulated Photocurrent Spectroscopy(IMPS) and Intensity Modulated Photovoltage Spectroscopy(IMVS) and other characterized by X-Ray Diffraction(XRD), Electrochemical Impedance Spectroscopy(EIS) and Solar simulater system. |
