WebThe benefits of CdTe thin-film solar cells include: High absorption: Cadmium telluride is a direct-bandgap material with bandgap energy that can be tuned from 1.4 to 1.5 (eV), which is nearly optimal for converting sunlight into … WebApr 11, 2024 · This effect starts around 500 nm towards lower wavelengths, which corresponds well with the CdS band gap (2.4 eV). In addition, the quantum efficiency increases as the CdS thickness decreases, which indicates less parasitic absorption, making it possible to generate a more significant number of charge carriers in the absorber.
