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 inclusion of a thicker aluminium oxide layer in TOPCon solar cells could provide superior resistance to UVID, according to UNSW.

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

PV Talk: Paul Gebhardt of Fraunhofer ISE discusses reliability issues facing advanced PV modules, an issue which isn't going anywhere.

Module quality issues, such as glass breakage, UVID and delamination, featured heavily in the discussions at PV ModuleTech Europe this week.

TOPCon solar modules show signs of accelerated degradation, which undermines the long warranties promised by many manufacturers, according to new findings from German researchers.

Researchers have called for enhanced international standards to detect ultraviolet-induced degradation (UVID) in PV modules after identifying “severe” levels of the problem in operational n-type panels.             

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.
