Corning gets first commercial order for photovoltaic glass

Three years of development work and extensive customer engagement at Corning Incorporated have resulted in an engineered glass that enables higher efficiency and lighter weight thin-film photovoltaic modules, for which the company has received its first commercial order.

Corning Incorporated has received its first commercial order for photovoltaic (PV) glass substrates. This milestone order follows three years of development work and extensive customer engagement, resulting in an engineered glass that enables higher efficiency and lighter weight thin-film photovoltaic modules.
“We understand the current market challenges for photovoltaics and the focus on delivering cost-effective solar energy solutions. Clearly, energy conversion efficiency is integral to addressing these challenges. Therefore, we are very excited about this initial deployment of Corning’s PV glass substrates and their ability to deliver on such an important need in the advancement of thin-film PV solutions,” said Dr. Gary Calabrese, senior vice president, Corning New Business Development. “The substantial efficiency improvement of our glass technology has been demonstrated in lab and customer trials. Now, this order validates the need for engineered glass to drive higher conversion efficiency and can provide module makers with a competitive advantage.”
Corning’s PV glass substrates can, the company says, increase current thin-film module efficiency by 20% to 30%. The glass has high transmission, allowing more sunlight into the semiconductor layer. Corning’s substrates are also high-temperature tolerant. Because the glass can withstand higher temperature deposition, more uniform semiconductor films may be applied, which increases overall conversion efficiency.
John Duke, business director for Corning Photovoltaic Glass Technologies, said, “Corning is committed to offering innovative glass substrates that enable increased solar conversion efficiency. This is just the beginning.”
