Figure 5From: Improving the efficiency of cadmium sulfide-sensitized titanium dioxide/indium tin oxide glass photoelectrodes using silver sulfide as an energy barrier layer and a light absorberUV-vis absorption spectra of TiO 2 / ITO, Ag 2 S/TiO 2 /ITO, and CdS( n ) /Ag 2 S /TiO 2 /ITO. UV-vis absorption spectra of the TiO2/ITO, Ag2S/TiO2/ ITO, and CdS(n)/Ag2S/TiO2/ITO (n =2 and 4) in the dark and under simulated AM 1.5 G sunlight irradiation (100 mW cm− 2).Back to article page
