Change of Dye Bath for Sensitisation of Nanocrystalline T i O 𝟐 Films: Enhances Performance of Dye-Sensitized Solar Cells

Figure 4

Film absorbance ratio versus normalized molar extinction coefficients of the sensitizers anchored on 7.0 μm thick mesoporous titanium films (a) ethanol bath (b) 1/1 v/v acetonitrile/tert-butanol mixture bath (here the low-energy maximum absorbance of HRD2 and H102 sensitizers are normalized relative to that of N719). An average of three film absorbencies of three different mesoporous TiO2 films gave error below ±2.5%.
