Fayetteville Startup Receives $746K From National Science Foundation

The University of Arkansas announced on Monday that the National Science Foundation has awarded a $746,366 grant to Fayetteville-based startup WattGlass LLC. The money will help further develop the University of Arkansas’s patent-pending coating technology that makes glass anti-reflective, self-cleaning and highly transparent.

Corey Thompson is the chief technology officer for WattGlass, a Genesis Technology Incubator client at the Arkansas Research and Technology Park. He founded the startup company in 2014 while pursuing a doctorate in microelectronics-photonics at the University of Arkansas.

“Solar panels collect dust, dirt and grime, which reduces output and increases the cost per watt,” Thompson said. “With our anti-reflective and self-cleaning coating, more light penetrates the glass to be turned into electricity by the solar cells.”

The coating’s nanostructure causes a self-cleaning effect on the glass by changing the way water reacts to its surface, which increases the efficiency of solar panels and reduces their cleaning and maintenance costs.

“When you put a drop of water on a normal piece of glass, the drop forms a bead and doesn’t generally move,” Thompson said. “With our coating, that drop of water spreads rapidly and when it does that it picks up dirt and other contaminants from the surface and literally pushes them to the edge of the glass. A light rain that would normally create mud on the surface of the panels suddenly is able to clean off the majority of the dirt.”

The National Science Foundation Phase II grant came through the Small Business Innovation Research Program, which allows federal agencies to stimulate technological innovation in the private sector by strengthening small businesses that meet federal research and development needs.

WattGlass will add two employees with the grant, Thompson said.
