The Institute for Optoelectronic Systems and Microtechnology (www.isom.upm.es) at the Universidad Politécnica de Madrid (ISOM-UPM), a leading Spanish research facility in optoelectronics, is offering a position for a highly motivated postdoctoral researcher to join a groundbreaking European Research Council funded project.
The project, entitled Quantum-engineered lattice-matched III-V-on-Si multijunction solar cells (MIRACLE, 101087086, ERC-CoG), focuses on the development of III-V tandem solar cells on silicon.
The successful candidate will be responsible for the modelling, epitaxy, processing, and characterization of tunnel junctions and III-V compound semiconductors in the form of short-period superlattices, with the aim of achieving pseudomorphic integration of III-V solar cells on silicon an essential milestone toward highly efficient and cost-effective photovoltaic devices for terrestrial applications.
The postdoctoral researcher will:
- Theoretically model tunnel junctions, short-period superlattices, and III-V solar cells on silicon.
- Grow nanostructures, tunnel junctions, and solar cells using molecular beam epitaxy (MBE).
- Process the grown materials into complete devices, which will subsequently be tested at ISOM-UPM.
Research activities will be conducted primarily at ISOM-UPM, in close collaboration with national and international partners who will provide access to advanced simulation and characterization facilities not available at the host institution.
