摘要
A new nondestructive quantitative method is developed to measure the adsorption of dyes in solid titania films for dye-sensitized solar cells. UV-vis spectroscopy study showed that the absorbance of dye in the solid film can be directly related to the absorbance measured by the typical destructive method used to quantify concentration. Concentrations of N-719 and N-749 dyes on solid titania films were successfully extracted using molar extinction coefficients of dye on solid titania films with value of 6916 and 6454 L·cmˉ1·molˉ1 respectively determined using the spectral peaks at 512 and 586 nm.
