It is desirable to obtain minority carrier lifetimes on real photovoltaic structures. However, the photoluminescence (PL) lifetime in such devices is less than the real bulk lifetime because of collection of carriers at the p-n junction. A transient analysis of the PL decay produces lifetime as a pa...
