NREL researchers quantify UV-induced degradation levels in TOPCon solar cells
Researchers at NREL found that UV exposure can cause significant, partly non-recoverable degradation in TOPCon solar cells, with strong cell-to-cell and intra-cell variability linked to passivation and processing inconsistencies. While some UV-related losses recover quickly under light and are unlikely to affect field performance, the findings highlight gaps in current qualification tests and the need for improved UV aging standards.
Enphase Energy cuts about 6% of workforce
Enphase Energy said it is cutting around 6% of its global workforce, affecting about 160 employees, as the company prepares for lower near-term demand following the expiration of the United States federal residential solar tax credit and moves to reduce costs through restructuring and automation.
