Enhanced Light Harvesting Efficiency with One-bath Mixed Dye Solution Process for Dye-sensitized Solar Cells. |
| 초록 |
There has been an increasing interest in the dye sensitized solar cell (DSSC) owing to a potential for highly efficient solar energy-to-electricity conversion efficiency, low-cost and easy manufacturing process. DSSC could be constructed with dye-absorbed wide band gap oxide semi-conductor electrode such as TiO2 or ZnO, electrolyte containing I-/I3- redox couples, and Pt coated counter electrode. In this paper, we designed and synthesized a series of organic photosensitizers containing long wavelength absorbing chromophore for the DSSC. The organic dyes containing squaraine chromophore could absorb long wavelength region which could be strong candidates for the Blue/NIR sensitizers for the DSSC. The photovoltaic properties and the incident photon-to-current (IPCE) efficiencies of DSSCs containing long wavelength absorbing organic chromophores were measured and evaluated by comparison with that of individual chromophores. |
