30. Photoexcitation is also found to affect the I-V properties of CdTe nanoparticles. However, the effects appear to be contingent upon the range of applied potential bias. When the bias voltage is smaller than the band gap, excitation by ambient light leads to a small but visible increase in the voltammetric currents. However, when the applied bias voltage is larger than the band gap, virtually no effect is observed from photoexcitation by ambient light, indicating that within this experimental context electron transfer is mainly driven by electrode potentials.
