recombination parameter, surface recombination, silicon plate


In this paper a new method of finding recombination parameters, such as surface recombination rate, "effective" and "bulk" lifetime of charge carriers, of a silicon plate based on only one measurement. This method is grounded on injection of charge carriers by pulse illumination of a local region of semiconductor’s fundamental absorption region with light and measuring the time dependence of concentration of non-equilibrium charge carriers. The method is tested in manufacturing conditions on technological silicon plates and may be used for quality control in manufacturing of solar elements.
