Truly green

Only 1 gram / m² of organic materials is required for the production of our solar films. Furthermore no toxic materials or heavy metals are used in the production process, permitting easy recycling of the films at the end
of their life.

Cost effective

To produce 1 m2 of our solar films, we need only 1 gram of organic material and a max. process temperature of 120°C.

The investment and operation costs are much lower than any crystalline or other thin film technologies.
