TOPCon solar modules show self-healing under UV stress

Researchers from Nanchang University and Trina Solar found that TOPCon solar modules exhibit metastable “degradation–recovery” under UV exposure, with light soaking fully restoring performance and no impact on real-world energy yield. Their findings highlight the need to refine UV testing standards to better reflect field performance and guide PV reliability assessments.A group of researchers from China's Nanchang University and solar module man…
