Understanding LeTID

Light- and elevated temperature-induced degradation (LeTID) of PV cells can have far-reaching impacts on the efficiency of modules. Alison Ciesla and Brett Hallam of the University of New South Wales argue that accelerated testing, such as that included in the forthcoming IEC standards, is critical for LeTID identification and quantification in order to manage these impacts.

Currently there are challenges, but thankfully there are also ways to minimize and eliminate the impact of LeTID. It will be the work of manufacturers, suppliers and consumers to ensure that we take the right path forward.As solar cell technologies continue to evolve and modules become more efficient, it’s inevitable that new degradation and failure …
