Light- and Elevated Temperature-Induced Degradation (LeTID): The Past, the Present and what Lies Ahead

Lightand elevated temperature-induced degradation (LeTID) has, in recent years, captured the attention of the global silicon photovoltaics industry. With over 180 publications and countless conference presentations from more than 40 universities, research institutes and manufacturers alike (see Fig. 1), there has been a range of studies conducted to understand the behaviours, kinetics, mitigation strategies and root cause of the defect. In this talk, we will provide a condensed review of the current global progress on LeTID research, highlighting recent theories, models, mitigation strategies and implications on the future of commercial silicon solar cells.
