Scratching the surface of LeTID
The devices behind light-elevated temperature-induced deterioration are still not completely comprehended, yet it is known to cause considerable efficiency losses for modules in the field. Researchers in China are investigating the causes of the sensation, as well as are currently concentrated on the surface area of the materials and the user interfaces in between the silicon and passivation layers.

German scientists research causes of LeTID
Scientists at Germany's Fraunhofer Institute for Integrated Solutions and Device Modern technology IISB are attempting to recognize the sources of light and elevated temperature induced degradation (LeTID) in PERC solar cells. First examinations must offer a comprehensive understanding of the process and also product dependence of LeTID and also associated degradation effects in monocrystalline and multicrystalline PERC solar cells.
