Size-dependent Scattering Efficiency in Dye-sensitized Solar Cell |
| 초록 |
Effect of scattering particle size on light scattering efficiency in dye-sensitized solar cell has been investigated with a FTO/semitransparent nano-TiO2 underlayer/scattering overlayer structure, where two different rutile TiO2 particles of 0.3 µm (G1) and 0.5 µm (G2) were used for a scattering layer and 20-nm anatase particle for nano-TiO2 layer. The conversion efficiency of 7.55% for the 7 μm-thick underlayer film is improved to 8.94% and 8.78% when G1 and G2 particulate overlayer is introduced, respectively. In case of the 14 µm-thick underlayer, the conversion efficiency is slightly improved from 8.60% to 9.09% and 9.15% upon depositing G1 and G2 particulate overlayer, respectively. Significant improvement and strong size-dependence upon deposition of scattering overlayer on the relatively thinner TiO2 underlayer film are associated with the quantity and wavelength of transmitted light and the difference in reflectivity of G1 and G2 scattering particles. |
