Which consequence results when crystal defects affect carrier mobility?

💡 Explanation

Crystal defects cause electron scattering, through the mechanism of reduced mean free path; because electrons can’t move as freely. Therefore, the efficiency of a photovoltaic cell's power output declines, rather than that of thermoelectric generators, resonant cavities, or piezoelectric devices.
