摘要
Photoconductivity spectra temperature dependence combining with transmission measurements have been formed on hydrogenated amorphous silicon.After exposure by AM1 light a reversible increase of 6%of the Urbach parameter E0(T,X)has been observed.This is a direct evidence for the fact that photo-induced changes in a-Si:H create not only metastable defects but also affect the topological disorder.
