In the present paper, we report the compensation effect on photoconductivity of thin films of Se70Te$_{30−x}$Cd$_{x}$ ($x = 2, 4, 6$) alloys for high field conduction. Steady state photoconductivity measurements have been made in thin films for different electric fields. The photoconduction was found to be ohmic at low fields and Poole–Frenkel type at high fields. Meyer–Neldel rule (MN rule) for the pre-exponential factor $(\sigma_{\text{ph}})_{0}$ and activation energy ($\Delta E_{\text{ph}}$) of photoconduction in thin films of Se70Te$_{30−x}$Cd$_{x}$ is observed in the present study.
