Increasing module sizes together with an IEC demand for higher testing doses are leading to a shortage of UV testing capacity globally. Eternalsun Spire has manged to meet the new market demands in a ...

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 ...

Engineers from UNSW have created a worldwide UV radiation map for solar panels, highlighting major differences in exposure depending on climate and mounting systems. Their new global study has ...

Senior Engineer Archana Sinha inspects modules in the UV chamber at the Kiwa PVEL lab in Napa, CA. Image: Kiwa PVEL As solar technology advances rapidly, a subtle yet serious threat has emerged – ...

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 ...

Reports of UV-induced degradation in TOPCon-based photovoltaic modules are currently preoccupying the PV industry. The Fraunhofer Institute for Solar Energy Systems (ISE) has been therefore ...
