We are looking for several highly motivated PhD students with a strong experimental background in materials, chemistry, and physics to develop high-efficiency and stable all-perovskite multi-junction solar cells and mini-modules on flexible substrates. You will have the opportunity to be embedded in a collaborative Horizon Europe research project. This will enable you to interact and collaborate with leading European academic and industrial partners. Your responsibilities (will vary depending on different projects) include:Develop high-throughput combinatorial materials synthesis platforms using thermal evaporation and/or thermal evaporation/slot-die coating method to accelerate the discovery of novel perovskite compositionsDevelop solution-processed (e.g., spin coating, slot-die coating) wide bandgap (~ 1.8 eV) and narrow bandgap (~ 1.2 eV) perovskite absorbers with both excellent optoelectronic properties and stabilityDevelop high throughput characterizations and in-situ/operando characterizations using electrons, photons, X-rays, ions, etc. to characterize the materials, layers, and devices (e.g., single-junction and multi-junction perovskite solar cells), and interpretation of resultsLayer deposition and device integration (e.g., single-junction and multi-junction perov-skite solar cells) using various deposition techniques, notably high-vacuum thermal evaporation, magnetron sputtering, atomic layer deposition (ALD) and slot-die coating etc.Conduct in-depth loss mechanisms analysis and use these insights to further improve the performance of perovskite single-junction and multi-junction solar cell and mini-modulesDevelop and implement novel concepts, such as light management, new materials and processing methods, novel tandem architectures, optical and electrical simulation, etc., to understand and ultimately improve the performance (both efficiency and stability) of flexible all-perovskite tandem solar cells and mini-modulesStability tests of single junction and multi-junction perovskite solar cells and mini-modulesDissemination of the results on meetings, reports, scientific journals and at conferencesMaintenance of equipment in collaboration with the laboratory technicianCo-supervision of semester- or master students together with supervisor
