Postdoctoral Researcher Solar Fuels
What you will do
The growth of renewable energy harvesting for power generation requires reliable storage capacity to deal with the intermittency of wind and sun. Batteries are certainly one part of the solution but will probably not be sufficient to bridge seasonal variations. In addition, the forthcoming electrification of transport will need high energy density storage solutions. Again, batteries will play an important role, but also hydrogen and synfuels (e.g. methanol) will be part of the solution, for example, in freight transport.
Hydrogen gas can be produced through the electrolysis of water – preferably with “green’ electricity from wind turbines or solar panels. In classical electrolysis, the power generation required for the reaction is done separately from the electrolyzer. Large throughput installations with electrolyzers designed to work at very large current densities and high pressures are needed to reduce the relative contribution of capital expenditure for the installation. However, local hydrogen production could be advantageous for certain applications and system environments. In this case. compact synergetic systems combining photovoltaic harvesting and electrochemical conversion using a similar modularity for the PV-system and the electrochemical part of the system are envisioned.
Imec has a built up a broad knowledge in the PV-domain with world-leading results over the last decade for crystalline Si solar cells, thin-film PV cells (amongst which perovskites) and lately also stacked cells with sufficiently high output voltage to supply the driving force for water splitting. This was evidenced by several best-in-class results achieved over the last year. The higher voltages of these stacked cells in combination our in-house nanomesh technology providing regular nanoporous metal electrodes with very large electrochemically active area, large porosity and mechanical rigidity represent a unique toolbox to design and develop novel compact water electrolyzers with efficient gas diffusion and gas evacuation, powered by solar energy.
We are looking for a post-doc with background in photovoltaics and/or in (semiconductor) electrochemistry to use this technology and material toolbox to come up with innovative designs, the proof-of-concept of such novel device designs, the detailed analysis of the performance-determining factors as well as a first assessment of reliability. The experimental work will be guided by electrochemical simulations. In addition, the post-doc will be enabled to extend the existing analytical equipment park with the necessary tools to evaluate the performance and detailed behavior of the thus developed solar fuel cells.
What we do for you
We offer you the opportunity to join one of the world’s premier research centers in nanotechnology at its headquarters in Leuven, Belgium.
