Trina Solar researchers propose new classification of ultraviolet-induced degradation in TOPCon solar cells Trina Solar researchers have proposed a new classification distinguishing reversible and irreversible ultraviolet-induced degradation in TOPCon solar cells. The framework aims to improve reliability testing, identify persistent performance losses, and provide more accurate assessments of long-term module performance under real-world conditions.

UV down-shifting layers could boost TOPCon solar module energy yield by over 4% Researchers in Slovenia have developed a numerical model showing that luminescent UV down-shifting layers could improve the long-term performance of TOPCon solar modules. Simulations suggest the technology could increase cumulative energy yields by more than 4% over 10 years while also mitigating UV-induced degradation.

Multiple grounding points cut lightning-induced overvoltage in solar panels by up to 55% Researchers in Indonesia found that higher soil resistivity significantly increases lightning-induced overvoltage in PV systems. Their simulations also showed that multiple grounding points and connections closer to the lightning strike location can substantially reduce transient voltages.

Study identifies new PID degradation mechanism in medium-voltage PV modules French researchers have found that increasing PV system voltage significantly worsens potential-induced degradation (PID), with encapsulant conductivity playing a key role in module performance. They also identified a new degradation mechanism involving partial discharges and electrical treeing, highlighting additional reliability risks for medium-voltage PV modules.

European storage inventories on the rise In an interview with pv magazine, Ali Arfa, analyst at EUPD Research, said China’s dominance of the global battery supply chain is unlikely to change significantly over the next two years. He expects rising inventories to put pressure on residential and C&I storage prices in Europe, while utility-scale battery prices should remain broadly stable.
