potential induced degradation

PV Tech Power spoke with Lukas Jakisch of PV testing company TÜV Rheinland about the developments and challenges facing the sector.

Tristan Erion-Lorico, VP of Sales and Marketing at PV Evolution Labs (PVEL), on the Inflation Reduction Act and its implications for the selection of materials going into producing solar modules.

Researchers in Saudi Arabia have reported the “the first ever” successful damp-heat test of perovskite solar cells, which they claim has moved the technology closer towards commercial viability after it withstood 1,000 hours of harsh conditions and maintained a 95% efficiency.  

After experiencing their own problems with potential induced degradation (PID), Belgium-based Edison Energy took matters into its own hands and developed the Pidbull solution in partnership with imec. Now it sells Pidbull to anyone experiencing issues with PID. As managing director Davy Verheyden explains, it is a problem solar asset owners cannot afford to ignore.

PV encapsulant films are crucial in the protection and long-term functionality of solar collection cells in PV modules. Dow's Andrew Yen discusses how choosing an alternative to EVA can lead to greater performance, improved yield and happier asset owners.

As demand for glass/glass modules increases, a rethink on encapsulant materials may be required, suggests Dow.

Asia-based EVA encapsulant material producer HIUV New Materials said it successfully developed an encapsulant for N-type cell based PV modules that limits PID (Potential Induced Degradation).
