PV Talk: Kiwa PVEL's Tristan Erion-Lorico discusses highlights in the 2026 Module Reliability Scorecard, including UVID and delamination.

For the fourth year in a row, Kiwa PVEL’s 2026 Module Reliability Scorecard registered a record high in module test failures.

Explainer: Two new studies offer fresh insights into the performance of TOPCon solar modules, including a new degradation mode related to encapsulants.

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.

As the year comes to an end, we bring you a recap of the most-read Premium stories that have been published throughout 2025.

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.
