Device development

Here, all the different material systems of the other working areas will have to be combined and tested and optimized as a whole. Working horse for light to electron-hole pair conversion with adjusted photovoltages will be different thin film Si multijunction cells. Efficient SPP-made noble metal free electrocatalysts shall be coupled to successful absorber materials in order to demonstrate the feasibility and to characterize the performance properties of an integrated device at an early stage. Special emphasis will be given to the aspects of long-term stability and on separated hydrogen and oxygen producing compartments.
