PhD scholarship in Experimental Development of Thin-Film Phosphosulfide Materials for Solar Cel
2 days ago
This PhD scholarship is part of the Inorganic Phosphosulfides for Optoelectronics project funded by the VILLUM Foundation. Our goal is to address a crucial scientific and technological challenge: How can we find the absolute best material for a desired application out of the enormous space of all possible materials, including the ones we haven't yet discovered (trillions at least)?
We will approach this question by working on a smaller-scale case study where we limit ourselves to one intriguing class of materials (phosphosulfides) and one important application (solar cells). Our team's task then becomes: among all possible phosphosulfides, which one will convert light most efficiently into electricity?
You will tackle this problem from an experimental angle. Phosphosulfide compounds are essentially unexplored in the thin-film form that is relevant for solar cells. You will have access to a new world-unique suite of thin-film processing setups highly customized for the inclusion of the "difficult" elements phosphorus and sulfur. The setups are glovebox-integrated and compatible with high-throughput deposition of combinatorial thin-film libraries with different elemental compositions in one process run.
Responsibilities and qualifications
You will be responsible for experimental work and related data infrastructure development as part of a diverse team of materials scientists, chemists, and physicists working on either experiment or computation. You will be supervised by Associate Prof. Andrea Crovetto and Prof. Eugen Stamate.
Your background could be Materials Science, Physics (emphasis on solid state physics is a plus), Chemistry (emphasis on inorganic/solid state chemistry is a plus), or related Engineering disciplines. Most importantly, you should be motivated to learn new things and push the boundaries of science.
Your tasks:
- Synthesize various phosphosulfide materials in thin-film form, using a custom suite of high-throughput deposition tools. The available techniques include reactive sputtering, evaporation, chemical vapor deposition, and reactive annealing.
- Measure the chemical, physical, and optoelectronic properties of phosphosulfides using state-of-the-art characterization tools at DTU Nanolab. Available techniques include x-ray diffraction, x-ray photoemission spectroscopy, electron microscopy, spectroscopic ellipsometry, photoluminescence spectroscopy and many others.
- Expand our current data infrastructure capabilities for batch analysis, visualization, and management of high-throughput experimental data based on the open-source NOMAD database model ( ).
- Exchange and analyze your data with other team members who are tackling the problem from other perspectives (e.g., by simulation, data mining, artificial intelligence).
- Fabricate simple solar cell prototypes using the most promising phosphosulfides you discover, and measure their efficiency and other performance indicators.
- Supervise BSc. and MSc. students in smaller projects related to your PhD work.
We expect the following from you:
- Some experience with vacuum-based thin-film deposition.
- Some experience with characterization techniques and analysis for thin-film materials (see examples in list above).
- Some experience with coding (preferably python).
- Ability to work both individually and as part of a team.
- Motivation to follow research tasks to completion and to summarize research outcomes in several scientific articles during your PhD.
You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Application procedure
Your complete online application must be submitted no later than 11 April 2025 (23:59 Danish time) . Applications must be submitted as one PDF file containing all materials to be given consideration. To apply, please open the link "Apply now", fill out the online application form, and attach all your materials in English in one PDF file . The file must include:
- A letter motivating the application (cover letter). Please name one (or more) phosphosulfide material you think is worth investigating for this project, and state why.
- Curriculum vitae.
- Grade transcripts and BSc/MSc diploma (in English) including official description of grading scale.
You may apply prior to obtaining your master's degree but cannot begin before having received it.
Applications received after the deadline will not be considered.
All interested candidates irrespective of age, gender, disability, race, religion or ethnic background are encouraged to apply. As DTU works with research in critical technology, which is subject to special rules for security and export control, open-source background checks may be conducted on qualified candidates for the position.
