Photoelectrochemical water-splitting for solar hydrogen production

Renewable energy research

The PECSYS project uses photovoltaic cells to power electro-catalysts that split water into hydrogen and oxygen. This technology directly converts solar energy into chemical energy stored in hydrogen fuel.

Technology that generates electricity through an electrochemical reaction between hydrogen and oxygen, with water as the only byproduct.
