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 ...

Fraunhofer’s research studied the relative power loss of various commercial module types after UV testing. Lines of the same colour represent tests on the same module types. The modules were measured ...

In 2024, researchers at Fraunhofer ISE analyzed the stability of TOPCon, passivated emitter and rear cell (PERC), and heterojunction solar cells under UV irradiation and found that all three cell ...

In an interview with PV Tech Premium, two UNSW researchers emphasise the need for enhanced UV testing for TOPCon solar cells.
