About Optical Additives GmbH

Convert any surface into a solar cell

New dimensions in light energy conversion: Flexible in shape, color and application

Optical Additives GmbH's product ZeoFRET® is a brand new, revolutionary additive for transparent polymers. These polymers then serve as a light harvester. The harvested light is  transferred to a solar cell and transformed  into electricity.

This material may be used to cast or to coat the body of any device with small embedded solar cells which then as a whole collects and transforms concentrated light.
