Staebler-Wronski effect in amorphous silicon and its alloys

The review gives the introductory information on metastable light-induced degradation of amorphous silicon called the Staebler-Wronski effect (SWE). The paper highlights some recent developments in our understanding of the effect as well as some successes in reducing the SWE. The latest results of the author’s experiments on the metastable effects and the degradation in thin film transistors and solar cells are also presented.
