Solarphire NaB glass for photovoltaic applications

PPG Industries

PPG Industries has introduced Solarphire NaB glass for solar applications where sodium leaching can adversely affect the performance of solar panels, reflectors, water heaters and other devices. The glass is formulated with a transparent barrier coating that retards the migration of sodium (Na) and other alkalis to the surface during high-temperature processing or long-term field exposure.

Solarphire NaB glass is temperable and highly durable, and suits virtually any solar application because the coating can be used on the first or second surface as needed. The glass is approved for concentrating photovoltaic (CPV) and concentrating solar power (CSP) applications where high in-use temperatures may be encountered.
