摘要
A new approach was proposed for the analysis of light current-voltage (I-V) characteristics of nonideal heterjunctions in the case of the dominating current transport mechanisms induced by multistep tunnel-recombination processes via interface states. I-V characteristics of the anisotype abrupt heterojunction n-TiO2/p-CdTe were investigated under different light conditions. The values of the series R-s and shunt R-sh resistance, as well as those of the coefficients alpha and B, which quantitatively describe the dominating tunnel-recombination current transport mechanism, were established to be strongly dependent on light conditions.
