The conversion efficiency of DSSCs can be improved by utilizing wavelength conversion material (WCM). WCMs have been found to perform efficient energy trasfer from the UV radiation absorbed by the organic ligands to the DCA for highly efficient DSSCs. The best result for a DSSCs employing a black dye/0.2mM WCM was achieved to be a short-circuit photocurrent density (Jsc) of 17.72 mA/cm-2, an open-circuit voltage (Voc) of 0.720 V, and fill factor (ff) of 72.79%, and an overall conversion efficiency of 9.28% under 100mW/cm2 irradiation. |
