Comparative Study between Dye-Sensitized and CdS Quantum-Dots-Sensitized TiO2 Solar Cells Using Photoinduced Absorption Spectroscopy
Figure 4
PIA spectra of CdS adsorbed at a nanostructured TiO2 film. Filled squares: in air; filled circles: in the presence of electrolyte. The spectra were recorded using blue light (460 nm) excitation (42 mW cm−2) with a modulation frequency of 9 Hz.
