PbTe and PbS films obtained on different substrates. It has been established that long-term heat treatment of PbS films leads to a change in the sign of the photovoltage at hv = 0.55 eV, and in the long-wavelength region of the spectrum at hv = 0.3 eV, the photoconductivity has a small maximum, which is due either to impact ionization or the generation of charge carriers from deep bands.
