Abstract :
The author reviews the significant advances made in the understanding of the Staebler-Wronski effect in a-Si:H-based materials, and its contributions to the light-induced changes in solar cells. Several unresolved issues related to the nature and origin of light-induced defects in materials and their effect on the long-term stability of a-Si:H-based solar cells are also reviewed, and an approach taken to address these problems is discussed
