Resonant Multiple Light Scattering for Photon Harvest Enhancement in Dye-Sensitized Solar Cells |
| 초록 |
The scattering property of the electrode film is quite important for the improvement of the light harvesting efficiency of the dye sensitized solar cells (DSSCs). The incident photon-to-current conversion efficiency was drastically improved (more than 30%) by the harmonization of the resonant multiple light scattering in the photoelectrode of the hierarchically structured TiO2 aggregates (an average size of 660 nm) with the photon absorption of the novel metal-free organic dye in the visible region. The DSSC yielded an unprecedented high photocurrent density of 20.9 mAcm-2, reaching the efficiency higher than 9% under 100 mWcm-2, AM 1.5 global illuminationwithout an antireflection layer. Using the novel metal-free organic dye, the device also displayed very good long-term stability when aged without a UV filter. |
