Fraunhofer ISE Invents New Technology To Manufacture Glowing & Colorful Solar PV Modules

The researchers based their technique on the surface structure of the wings of the morpho butterfly – a tropical American butterfly species with dazzling iridescent wings, usually with a pronounced blue area.

The Fraunhofer ISE scientists succeeded in applying a similar surface structure to the back of the cover glass of their solar modules using a vacuum process.

“The sparkling idea for the development was not to color the cover glass of the modules with color pigments, but rather to imitate the physical effect of the butterfly’s wing,” said Thomas Kroyer, head of Coating Technology and Systems at Fraunhofer ISE. “If the glass was coated with pigments, the solar modules would lose much of their efficiency, as the light can no longer penetrate the module unhindered.”
