Linde Gases has announced the launch of S-COAT®, a highly innovative and cost-effective anti-reflection (AR) coating technology that significantly increases light transmission values and the energy yields of solar modules.

Linde Gases has developed the new technology together with LiSEC, an Austrian-based company specializing in glass processing.

The new anti-reflection solar glass coating technology delivers light transmission gains of around three percent on average – and up to 3.5 percent in peak conditions – compared to identical glass substrates without such a coating.

“Solar module manufacturers are under pressure to optimize costs,” said Ulrich Hanke, global manager marketing and business development, metals and glass, Linde Gases Division.

“S-COAT® is a highly economical solution for effectively improving energy yields as it provides significant advantages from both a capital and operating expenditure viewpoint, as compared to competing technologies.”

The innovative and patented S-COAT® coating process comprises the application of a specially developed water-based chemical mixture onto the glass surface using an inert gas spraying technology – and results in a glass surface finish of controlled porosity, maximizing light transmission.

This technology can be installed into existing glass processing lines and operates at speeds of up to 15 meters per minute, meaning no loss to productivity. “This important development means that customers can not only benefit from the best anti-reflective coating solution, but can do so at low cost and without disrupting manufacturing,” continued Hanke.

S-COAT® also has the benefit of proven durability. After the coating is applied, the glass sheets are tempered to create a highly damage and wear resistant finish for the solar module.
