摘要
The kinetics of light induced defect generation was investigated by light soaking experiments (i) under constant photocurrent and (ii) at low temperatures and under constant illumination intensity. For constant density of photogenerated carriers, the rate of defect formation decreases as more defects are formed, indicating the existence of a distribution of defect formation energies in the amorphous network.
