The described experimental data indicate the tunnel-jumping character of carriers
transport through space-charge region (SCR) of heterojunction CdS—Cu2S. The conductivity
caused by this mechanism essentially depends on the barrier parameters which can
vary under illumination. This conductivity has the determinative influence on photo-electric
properties of CdS—~Cu2S heterophotoelements. Rather low efficiency values of these elements,
small Uoc values and, in many cases, the rectification factor of volt-current characteristics
(VCC) are caused by junction external shunting as in the case the element
conductivity would not find out the listed above features. In spite of similar VCC, the
elements with various shunting mechanisms their character (tunnel-jumping transport on
the located levels through a barrier or external with respect to junction transport) can be
easy determined experimentally.
