UV degradation

Researchers from the University of New South Wales (UNSW), Australia, have directly observed how silicon solar cells can self-repair UV damage under sunlight.

The PV Review, 2025: this year has seen many papers and reports on solar PV modules reliability and performance issues, especially with TOPCon.

Greater awareness of UV light used to test solar cells could result in faster, more efficient assessments of long-term performance.

Kiwa PVEL examines the ultraviolet-induced degradation (UVID) results on n-type technology from its latest PV Module Reliability Scorecard.

Concerns over the performance of TOPCon solar cells following UV exposure may be exaggerated, according to research by Germany’s Fraunhofer Institute for Solar Energy Systems (ISE).
