Optical bias (illumination intensity) and Staebler-Wronski (illumination history) effects on the paramagnetic defects (dangling bonds) in undoped amorphous hydrogenated silicon are investigated using absorption mode electron spin resonance (ESR). The change in the ESR signature (spectrum and spin relaxation) while under illumination is compared with the absence of significant signature changes in the dark spectrum even following a substantial illumination-induced increase in the defect density.
