PhD student position in synthesis of high band-gap thin film solar cells
Uppsala University is an international research university focused on the development of science and education. Our most important assets are all the individuals who with their curiosity and their dedication make Uppsala University one of Sweden’s most exciting work places. Uppsala University has 40,000 students, 7,000 employees and a turnover of SEK 6,5 billion.
PhD student position in the subject Engineering Science with specialization in Electronics at the Ångström Laboratory, Department of Engineering Sciences, Division of Solid State Electronics. Starting date fall 2017 or according to agreement.
Renewable energy sources are important to build a lasting modern society, and photovoltaics is one of the fastest growing technologies of today. Solar cells made from the semiconductor compound Cu(In,Ga)Se2 (CIGS) are under continuous development, both in research and in industry, with a highest achieved efficiency of 22.6 %. CIGS solar cells are so-called thin film solar cells that consist of several thin layers, grown by different techniques, on support materials such as glass. To further increase the knowledge in the field of CIGS solar cells, extensive research is performed at the Ångström Laboratory. More information can be found at http://www.teknik.uu.se/solid-state-electronics+/research-areas/solar-cells/.
The purpose of this PhD project is to develop a CIGS solar cell with high bandgap for application as the uppermost solar cell in a tandem device. In tandem cells, a structure with two materials of different bandgaps is used to increase light absorption and thereby improve the efficiency. There are many requirements that need to be met in order to produce a well-functioning top cell. It should have high efficiency and be transparent to light with low energy. At the same time, new transparent and temperature-stable contact materials must be developed. The project builds on the research group's recently published world record of 11.9% for a CuGaSe2 solar cell with a band gap of 1.7 eV. The work includes fabrication of thin films and complete solar cell devices in the Ångström Laboratory cleanroom together with extensive characterization of material properties.
The thin film solar cell research group currently consists of around 25 senior researchers, post-docs, PhD students and 1 research engineer.
The successful candidate should have a Master of Science in materials science, materials chemistry, engineering physics or equivalent. Previous laboratory experience in the area of thin film synthesis is considered a merit. Strong collaborative spirit and good communication skills in oral and written English are required.
The PhD position is for four years, extendable to a maximum of five years, including departmental duties at a level of at most 20% (typically teaching).
Applications should include a brief description of research interests and past experience, CV, copies of exams, degrees and grades, a copy of your Master thesis (or a draft thereof) and other relevant documents. The candidates are encouraged to provide letter(s) of recommendation and contact information to reference persons.
Uppsala University strives to be an inclusive workplace that promotes equal opportunities and attracts qualified candidates who can contribute to the University’s excellence and diversity. We welcome applications from all sections of the community and from people of all backgrounds.
Pay: According to local agreement for PhD students and teaching assistants.
Starting: Starting date fall 2017 or according to agreement.
