Company history

Solibro GmbH is one of the world‘s leading manufacturers of CIGS thin-film modules, with a production capacity of 145 MW. Solibro has headquarters in Thalheim, Germany and a research site in Uppsala, Sweden, both of which work to develop trailblazing solutions for the company‘s CIGS products. Solibro supplies products that are sustainable and cost-effective, with extraordinary aesthetics and top quality “Made in Germany“.


CIGS (Cu, In, Ga, Se2) has the highest efficiency potential among thin-film solar cell materials. The CIGS technology of Solibro is based on extensive research and development carried out at Uppsala University. These activities resulted in world class results, such as the current world record CIGS thin-film modules with 18.7% efficiency, and were the basis for the spin-off company Solibro AB. Development in Uppsala is now continued with expanded resources at Solibro Research AB, a subsidiary of Solibro GmbH.
