Comparative Study between Dye-Sensitized and CdS Quantum-Dots-Sensitized TiO2 Solar Cells Using Photoinduced Absorption Spectroscopy
Figure 3
Photoinduced absorption (PIA) spectra of quantum dots CdS-modified TiO2-NP electrode (circle) in air and CdS on conducting glass ITO (square). The spectra were recorded using blue light (460 nm) excitation (42 mW·cm−2) with a modulation frequency of 9 Hz.
