Abstract

Correlation between spectrum of the low temperature (T  4.2 K) photoluminescence and anomalous photovoltages properties of slanting evaporating polikryistallin thin films CdTe, CdTe : In is discovered. In spectrum undoped sample on a number double-acting by band dominated the band to own luminescence, conditioned presence potential barrier on border of grains. Alloyage an impurity In brings about stewing doubleacting bands, but the most further thermal processing - to cutting the activations of the own band, full width on half maximum which is bound by maximum value photo generated voltage V V sm АPV 10 / 3 
