Concomitant studies of kinetics of defects ND(t), photoconductivity σph(t), electron and hole diffision lengths Le(t), Lh(t) during light soaking have been carried out. The data have been fitted by stretched exponential expressions and characteristic parameters of kinetics have been determined. Correlation between the kinetics is discussed. In contrast to Nd(t), σph(t) and Le(t), the hole diffusion length Lh(t) was observed to remain constant during initial time (˜ 103s) and then decreased with characteri stic time ˜ 104s.
