Job description

Metal halide perovskite (MHP) semiconductors, such as methylammonium lead iodide (MAPbI3), have recently received tremendous attention in materials science, as these have yielded high efficiency solar cells, X-ray detectors and LEDs. However, one of the most fundamental material properties of MHPs still remains debated: whether their band gap is direct or slightly indirect. The nature of the band gap determines both the light absorption properties and the lifetime of light-generated charge carriers. Both of these properties are important for e.g. the efficiency of a solar cell or the suitability of MHPs to be used as photocatalysts.

This project aims to reveal the nature of the band gap and investigate whether this can be manipulated. You will use optical spectroscopy techniques to study the absorption of light and the recombination of charge carriers as a function of temperature and pressure, and develop models to analyze the data. Finally, you will make a link between the band gap and the photocatalytic activity of MHPs.

Qualifications

You are an enthusiastic, highly motivated and skilled student holding an MSc in a relevant area of Chemistry, Physics or Materials Science.

Offer

  • a full-time position for 1.5 years, which can be extended to 4 years if the candidate functions well;
  • full-time gross salary ranging from €2,325 to €2,975 (scale P according to the Collective Labour Agreement Dutch Universities);
  • benefits including 8% holiday bonus and 8.3% end-of-year bonus;
  • the candidate will be provided with the necessary support on all aspects of the project by the research group.

In addition, we offer a pension scheme, a partially paid parental leave and flexible employment conditions. For more information about Utrecht University jobs, please click here.

About the organisation

You will be embedded in the ARC Chemical Building Blocks Consortium (ARC-CBBC), a research center that focuses on finding novel chemical building blocks for sustainable energy applications. ARC-CBBC is a partnership between several universities, including Utrecht University, and industrial partners, making it a highly collaborative work environment.

The Department of Chemistry addresses teaching and research about chemistry. Starting already at the first year of the Bachelor's Chemistry programme, students are trained to become well-rounded scientists with many practical courses and multiple internships within research groups. Three different Master's programmes are available after the general chemistry education of the Bachelor's programme. One Master's programme focuses on Biochemistry, one focuses on the entrepreneurial side of research and the final Master's programme focuses on Physical Chemistry. Postdoctoral fellows are expected to be involved in the supervision of (Bachelor's/Master's) students or even PhD candidates.

 

At the Faculty of Science there are 6 departments to make a fundamental connection with: Biology, Chemistry, Information and Computing Sciences, Mathematics, Pharmaceutical Sciences and Physics. Within each department there are distinct institutes which focus on answering some of humanity’s most pressing problems. These institutes are further broken up into research groups.

 

Utrecht University is a friendly and ambitious university at the heart of an ancient city. We love to welcome new scientists to our city – a thriving cultural hub that is consistently rated as one of the world’s happiest cities. We are renowned for our innovative interdisciplinary research and our emphasis on inspirational research and excellent education. We are equally well-known for our familiar atmosphere and the can-do mentality of our people. This lively and inspiring academic environment attracts Professors, Researchers and PhD candidates from all over the globe, making both the University and the Faculty of Science a vibrant international community and wonderfully diverse.
