CTF Solar GmbH

Solar cells created using a thin-film technology that employs inexpensive materials such as zinc and iron instead of costly materials like iridium. IBM's process demonstrated conversion efficiency of 9.6% in 2010.

A process that uses solar energy to directly produce hydrogen. It involves a photoelectrochemical cell that harnesses sunlight to split water molecules.

An innovative design developed by Honda that separates hydrogen and oxygen without using environmentally persistent chemicals like PFAS.

A demonstration of SunHydrogen's solar-to-hydrogen technology scaled to 1 square meter, conducted in December 2024 in Coralville, Iowa. The demonstration validated the system's functionality in real-world conditions including subfreezing temperatures.

Planned larger-scale installations of SunHydrogen's technology at 25 square meters, representing the next phase of scaling toward commercial deployment.

Testing of SunHydrogen's 100cm² hydrogen modules at Honda R&D facility in Japan, achieving 10.8% solar-to-hydrogen efficiency in October 2024.

A scaled-up demonstration of SunHydrogen's solar-to-hydrogen technology at 1 square meter, combining CTF Solar GmbH solar cells with water electrolysis. Demonstrated in December 2024 in Coralville, Iowa, with validated functionality in subfreezing temperatures.

Large-scale hydrogen production modules incorporating SunHydrogen's proprietary nanoparticle technology. The modules split water into hydrogen and oxygen using solar energy, operating autonomously without environmentally harmful compounds. Designed to function similarly to solar panels with billions of electroplated nanoparticles.

Large-area photoelectrochemical hydrogen modules incorporating improved catalyst integration, coating strategies, and absorber layout.
