Change of Dye Bath for Sensitisation of Nanocrystalline T i O ๐Ÿ Films: Enhances Performance of Dye-Sensitized Solar Cells

Figure 4

Film absorbance ratio versus normalized molar extinction coefficients of the sensitizers anchored on 7.0โ€‰ฮผm 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 ยฑ2.5%.
