Abstract :
We investigate the diode ideality factors obtained from the photovoltaic characteristics and compare them with the ones from the conventional current-voltage characteristics. By eliminating the series resistance in the bulk region, the ideality factors from the photovoltaic measurements can give more accurate information on the recombination processes and the defects in the active quantum wells.
