Research from pv magazine indicates that a specific type of solar module exhibits a reversible performance change when exposed to ultraviolet light. A joint study by Nanchang University and Trina Solar investigated ultraviolet-induced degradation in tunnel oxide passivating contact, or TOPCon, solar modules.
The laboratory experiments involved accelerated UV aging tests on TOPCon cells under controlled temperature and irradiation conditions. After irradiation, samples were kept in darkness for a week before being exposed to natural sunlight for one day. Performance was tracked using current-voltage measurements and imaging techniques throughout the process. Modules constructed from different cell types were also tested outdoors in China.
The analysis found that TOPCon modules undergo a metastable cycle of degradation and recovery when subjected to UV light, dark storage, and subsequent light exposure. This behavior is linked to charge redistribution and hydrogen-mediated processes. While some module types showed greater sensitivity to UV in testing, their average energy yield over several months was nearly identical.
Field results confirmed that the light-induced recovery effectively mitigates the UV-induced degradation, leading to stable power output under real-world operating conditions. The researchers concluded that this degradation has no impact on actual energy production.
The findings suggest that current industry standards for UV testing could be refined to more accurately represent field performance. The researchers advocate for further investigation into the specific UV thresholds that trigger degradation and recovery across different photovoltaic technologies.
