WebBy far the most widely used III-V solar cell is gallium arsenide (GaAs), which has a band gap of 1.42 eV at room temperature. It’s in the range of the ideal bandgaps for solar absorption, and it has the bonus of having a direct-gap absorption, which means that the lattice vibrations don’t matter in deciding whether or not light will get absorbed. WebJul 31, 2024 · Some of the established thin film solar cells are gallium arsenide (GaAs), cadmium telluride (CdTe) and copper indium gallium selenide (CIGs). Among all the existing thin film photovoltaic technologies, cadmium telluride (CdTe) occupies more than 95% of the thin film solar cell market because of its mature technology and minimum cost.
