a, Dark current–voltage evolution of p-a-Si:H thin film as a function of light soaking time under 1 sun illumination (100 mW cm–2 at 25 °C). The curves are linear fits through the origin (0, 0). b, Dark current–voltage evolution of light-soaked p-a-Si:H thin film as a function of time in the dark following light soaking. The curves were fitted using equation (1), where the derived results are summarized in Supplementary Table 1. c, Normalized decay of Δσdark fits to a combination of Debye model and Williams–Watts model.
