Artificial Photosynthesis

Direct solar-to-hydrogen conversion achieving 19% efficiency through artificial photosynthesis systems. Tandem photoelectrochemical cells enable direct solar fuel production without external electricity.

How It Works

Artificial photosynthesis systems mimic natural plant processes using specialized catalysts and photoelectrochemical cells to split water directly with sunlight. Tandem photoelectrochemical configurations stack multiple light-absorbing layers to achieve higher efficiencies for hydrogen production. Advanced catalysts enable direct conversion of solar energy to chemical fuels.

Advantages
