New framework pinpoints faulty modules in utility-scale PV plants Spanish researchers have developed a three-phase framework that uses unmanned aerial vehicles to map PV plants, identify defective modules and assess fault severity. Tested at two utility-scale facilities in England, the method achieved module-detection accuracy of up to 98.55% and fault-classification accuracy of 96.6%.

Scientists explain unexpected hotspot formation in half-cell heterojunction modules Researchers in Japan have identified the circuit-level mechanism behind hotspot mirroring in half-cell HJT modules, showing that current mismatch can drive localized overheating in unshaded cells. The study combines outdoor measurements and simulations to reveal key design factors influencing hotspot severity, offering guidance for improving half-cell module reliability.

Exploring electrochemical recovery of silver from end-of-life solar modules Australian researchers have identified 316L stainless steel as an effective electrode material for recovering silver from recycled PV cells, achieving up to 93% recovery and 96% Faradaic efficiency. The study shows that optimizing current density improves silver deposition, while copper contamination affects electrochemical behavior without causing significant co-deposition.
