Sunscreen for solar cells

Laboratory testing has revealed that some negatively-doped, “n-type” tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) solar modules are susceptible to ultraviolet (UV) light-related damage and degradation. That could mean trouble down the line, if modules in the field begin to show UV-related performance loss. Manufacturers are implementing solutions at cell and module level.

HJT module maker Huasun has integrated an encapsulant material that converts UV photons to visible light into its modules, mitigating UV degradation without blocking light from the cell and reducing its performance.
