Concerns over the performance of TOPCon solar cells following UV exposure may be exaggerated, according to research by Germany’s Fraunhofer Institute for Solar Energy Systems (ISE).
A team of researchers from DEWA R&D Center, Dubai has undertaken a comprehensive review of PV module degradation in desert environments. Their research proposes a new test cycle to identify defects induced in PV modules by harsh desert conditions.
Degradation issues identified in new cell technologies such as TOPCon and HJT underscore the importance of module stability as well as efficiency. Tom Kenning reports on the testing of next-generation modules and efforts to ensure their longevity in the field.
Concerns have been raised that the US solar industry’s reputation could be impacted by underperforming assets if investors do not see their return profiles being realised several years down the line.
