We observe a reversible photo-induced modification in the bulk density of gap states in hydrogenated amorphous silicon associated with the Staebler-Wronski effect. Detailed analysis of deep level transient spectroscopy, admittance and thermally stimulated capacitance measurements indicates that as a
