Longi backs Carbon’s shift to GW-scale solar production in France
France-based startup Carbon plans to partner with Chinese manufacturer Longi and adopt back-contact (BC) solar technology as it revises its roadmap for a gigawatt-scale solar module factory.
The impact of laser-assisted firing on TOPCon solar cell performance
UNSW and Jolywood studied the thermal stability of laser-assisted fired TOPCon solar cells during module fabrication and high-temperature stress, identifying hydrogen-related defect dynamics as the key factor behind degradation and recovery. They found lamination causes temporary efficiency losses that self-recover under light exposure, while optimized LAF can restore degraded contacts, providing practical guidance for reliable module manufacturing and testing.
