Abstract
► Thermally evaporated CdTe films exhibit space charge limited conduction over a temperature range of 220-440 K at higher voltages. ► The characteristic temperature is determined as 380 K. ► The calculated density of traps distribution is 1.18 × 1023 m−3 eV−1. ► The activation energy of traps determined from the I-V-T measurements is found to be 0.5 eV.
