摘要: The decay of stationary photocurrents on a-Si:H Schottky and nip diodes is investigated. transient current attributed to deep trapping thermal emission electrons. A good fit curves obtained from Shockley-Read statistics. Injection recombination are shown be minor effects under normal conditions.
