Perovskite solar cells have rapidly advanced towards high power conversion efficiencies, yet their sensitivity to moisture, oxygen, heat and mechanical stress has hindered long-term operation.

Chinese researchers have demonstrated organic solar cells with novel encapsulation and a protective interfacial layer for enhanced stability and efficiency. The best performing cell based on the new ...

UNSW researchers identified a new damp-heat degradation mechanism in TOPCon modules with laser-fired contacts, driven primarily by rear-side recombination and open-circuit voltage loss rather than ...

Hail durability testing saw a decline in ‘high achiever’ results from 70% to 27% between 2025 and 2026. Image: Marian Heinkel, RETC. Damp heat testing of solar PV modules yielded 11% “red flag results ...
