Sažetak
Two independent methods, the gamma-ray induced photovoltaic effect and the monochromatic light induced photoeffect, were used for determination of the minority carrier lifetime in indium doped n-type CdTe. The existing expressions for collection efficiency of electron-hole pairs generated by visible light near the p-n junction were extended to include a contribution of the depletion layer. P-n junctions formed by electroless plating of gold had a relatively high capacitance associated with a very narrow depletion region. The short-circuit current of the diodes was measured during irradiation in the Co60 gamma source. The values of lifetime of holes in CdTe (of the order of 5 *10-10 s), obtained by the two methods, were in agreement within the limits of experimental errors.
