Light elevated temperature induced degradation

The struggle against LeTID continues

Researchers in Australia have conducted extensive research on all possible causes behind the light-elevated temperature-induced degradation (LeTID) in solar panels and presented a few mitigation strategies put in place by manufacturers to reduce its effects.

Scratching the surface of LeTID

The mechanisms behind light-elevated temperature-induced degradation are still not fully understood, but it is known to cause significant performance losses for modules in the field. Scientists in China are investigating the causes of the phenomenon, and are currently focused on the surface of the materials and the interfaces between the silicon and passivation layers.
