Photoelectrochemical cells (artificial leaves)

Materials and energy research

Devices that use artificial photoelectrodes to split water into hydrogen and oxygen using sunlight. They are also known as artificial leaves and can achieve energy conversion efficiencies up to 19%.

Computational approach developed by HZB researchers to simulate and predict the behavior of PEC cells under various pressure conditions, accounting for bubble dynamics, light scattering, and electrochemical reactions.

A process used by Hydrogenics to produce hydrogen, which can be stored and later converted back to energy through fuel cells.

Berlin

Research project investigating the effects of elevated operating pressures (1-10 bar) on photoelectrochemical cell efficiency for hydrogen production. The study combined experimental work with multiphysics modelling to optimize bubble dynamics and overall performance.
