Microfabrication for solar-to-hydrogen devices

Climate change and the depletion of fossil fuels urge us to switch to more renewable energy sources. There is more than enough sunlight to provide all the energy that we need. However, because the sun does not always shine, we need a way to store this energy for later use. Solar-to-hydrogen devices generate a fuel which can be stored, instead of electricity which has to be used directly when it is generated. This PhD thesis investigates the usefulness of microstructuring for such devices, microstructuring that is achieved with techniques that are also used for computer chip fabrication.
