PhD student in Energy material physics with specialization on Solar cells
Uppsala University is a comprehensive research-intensive university with a
strong international standing. Our ultimate goal is to conduct education and
research of the highest quality and relevance to make a long-term difference
in society. Our most important assets are all the individuals whose curiosity
and dedication make Uppsala University one of Sweden's most exciting
workplaces. Uppsala University has over 45,000 students, more than 7,000
employees and a turnover of around SEK 7 billion.
The research conducted at the Department of Physics and Astronomy encompasses
a wide range of topics in physics, distributed over ten divisions. The
department is located in the Ångström laboratory and employs nearly 400
people, 125 of whom are doctoral students. It offers a broad physics
curriculum to undergraduate and graduate students, participation in nationally
and internationally leading projects for researchers, and opportunities for
partnership with industry and various outreach activities. More information to
be found on our website www. physics.uu.se.
The Division of X-ray Photon Science is world-leading in the development of
x-ray-based spectroscopy. It includes the program Condensed Matter Physics of
Energy Materials, and conducts research to develop our understanding of
electronic properties at the atomic level in new functional, for applications
in energy and environmental technologies.
Project description: Among the different emerging energy technologies,
optoelectronic devices based on perovskite metal halides are a rising star.
These include highly efficient solar cells. The accelerating development
demands detailed knowledge of the atomic processes that contribute to
efficient energy conversion. Advanced methodologies that have been developed
by the Division of X-ray Photon Science constitute unique tools to acquire
such knowledge. This includes new opportunities for Photoelectron Spectroscopy
and X-ray absorption for understanding the physics of solar cells. This
project focuses on interface characterization of well-defined Perovskites,
specifically chalcogenide single crystals, with the information obtained being
compared to findings on polycrystalline films and targeted towards development
of real functional device structures. A specific focus is on understanding
electronic properties and their relation to selective electron/hole transfer
processes at interfaces and on a device operation. The project spans
fundamental to applied research.
Work duties: To investigate the electronic structure of new perovskite
materials using in-house and synchrotron-based X-ray spectroscopy and
complementary methodologies. to actively engage in in-situ sample
preparation for fundamental studies of perovskite material interfaces to use
the experimental results in modeling the physics that limit the efficiency of
the materials, and in the development of design rules for new device
The successful candidate for this PhD student position will have opportunity
to study a variety of solar cell materials, specifically chalcogenides, using
x-ray-based methodologies such as photoemission and x-ray absorption and
complementary techniques. The candidate will be part of a collaborative
research group that share the same general goal of unraveling the mechanisms
that take place in such interesting and challenging energy materials.
The position of Ph.D. student is limited to four years of full-time studies,
consisting of research and coursework. Other duties at the department, related
to teaching and administration, may extend the position at a level of most
20%. Further information is available at www. physics.uu.se.
Requirements: The candidate should be highly motivated to pursue
experimental x-ray-based research in an active team with interest to immerse
oneself into physics aspects as well as advanced sample preparation aspects.
The candidate should hold a master's degree (or equivalent) in physics
(possibly physical chemistry).
Fluency in both spoken and written English is an absolute prerequisite.
Additional qualifications: A solid education in materials physics or
Consideration will also be given to good collaborative skills, drive and
independence, how the applicant's experience and skills complement and
strengthen ongoing research within the department, and how they stand to
contribute to its future development.
Rules governing PhD students are set out in the Higher Education Ordinance
chapter 5, §§ 1-7 and in Uppsala University's rules and guidelines.
Application: The application should include a personal letter, explaining
scientific interests and motivation for pursuing a Ph.D. degree, CV, and a
verified list of course grades. If available, a Master's thesis (finished or
in draft form) can also be included. Also, contact information of at least
two reference persons should be included.
Salary: According to local agreement for PhD students.
Starting date: 2021-10-01 or as otherwise agreed.
Type of employment: Temporary position according to the Higher Education
Ordinance chapter 5 § 7.
Scope of employment: 100 %.
