Abstract
The effect of light induced degradation, the Staebler-Wronski effect, of amorphous silicon technology has caused some concern in the initial steps of market introduction for this technology. Another effect present in all photovoltaic technologies is the long term irreversible degradation. The present paper deals on both effects and their impact on the long term performance of amorphous silicon photovoltaic modules.
In addition, other of the concerns about the technology was the long term reliability; in this case the concern was caused by some initial failures of the early amorphous silicon modules with deficient encapsulation. Modern amorphous silicon technology usually provides glass-glass encapsulation that, together with laser interconnection and highly automated manufacturing, provides a very reliable module performance in the field. The best evaluation for the inter-annual performance degradation of the amorphous silicon modules is estimated at −0.51%/year.
