Improvement of photocathode longevity in photoelectrochemical water-splitting devices

Renewable energy research

A component developed by researchers that uses solar energy to generate electrical power for electrolysis.

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.

Solar cells that combine two or more different semiconductor materials to absorb a wider range of the solar spectrum, thereby increasing overall efficiency. Perovskite is being explored for use in tandem approaches with silicon.
