On the mechanism of light-induced effects in hydrogenated amorphous silicon alloys

Abstract
We have investigated the effects of both forward bias current soaking in the dark and prolonged light exposure on the photovoltaic properties of lightly doped, n‐ and p‐type hydrogenated amorphous silicon Schottky barrier diodes. The results show that recombination rather than single carrier trapping is responsible for the light‐induced changes.
