How to reduce abrasion damage to PV module antisoiling coatings during robotic cleaning Researchers in India found that dust during robotic cleaning can dramatically accelerate the degradation of hydrophobic antisoiling coatings on PV modules. Softer brushes, higher cleaning speeds, optimized cleaning intervals, and appropriate brush rotation can significantly extend coating lifetime.

New research confirms negligible LeTID degradation in TOPCon solar cells US researchers have found that light- and elevated-temperature-induced degradation (LeTID) has a limited impact on n-type TOPCon solar cells compared with earlier p-type PERC technology. Optimized firing conditions and laser-enhanced contact optimization (LECO) can further suppress degradation, with industrial TOPCon cells showing efficiency losses within acceptable warranty tolerances.
