Optical Hall Effect of PV Device Materials

Electrical transport properties [carrier concentration (N), mobility (μ), effective mass (m*), resistivity (ρ), and scattering time (τ)] are deduced from free carrier optical absorption using noncontacting optical Hall effect measurements. Here, we use this technique to determine N, μ, and m* for semiconductor absorber materials for photovoltaic (PV) devices. As case studies, PV component material...
