DYE-SENSITIZED SOLAR CELL (DSC) WITH ENERGY-DONOR ENHANCEMENT, METHOD FOR FABRICATING DSC AND METHOD FOR GENERATING PHOTOCURRENT USING DSC |
摘要 |
A co-sensitized dye-sensitized solar cell (DSC) is provided, made from a transparent substrate and a transparent conductive oxide (TCO) film overlying the transparent substrate. An n-type semiconductor layer overlies the TCO, and is co-sensitized with a first dye (D1) and a second dye (D2). A redox electrolyte is in contact with the co-sensitized n-type semiconductor layer, and a counter electrode overlies the redox electrolyte. The first dye (D1) has a first optical absorbance local maxima at a first wavelength (A1) and a second optical absorbance local maxima at a second wavelength (A2), longer than the first wavelength. The second dye (D2) has a third optical absorbance local maxima at a third wavelength (A3) between the first wavelength (A1) and the second wavelength (A2). In one aspect, the first dye (D1) includes a porphyrin material, for example, a metalloporphyrin obtained by complexation with a transition metal such as zinc (i.e. zinc porphyrin (ZnP)). |
