Postdoctoral Researcher in Solid State Physics

Lunds Universitet · Full-time

Professorsgatan 1, Lund, Sweden

Lund University was founded in 1666 and is consistently ranked as one of the world's leading universities. The university has approximately 46,000 students and 8,500 employees in Lund, Helsingborg, and Malmö. We are united in our mission to understand, explain, and improve our world and people's living conditions. Description of the Workplace This position is attached to the Department of Solid State Physics at the Department of Physics, a department with approximately 100 employees where extensive research is conducted centered on various aspects of nano- and semiconductor physics, ranging from materials science to bio- and quantum physics with various applications. The department is a central part of NanoLund, which is Lund University's major interdisciplinary research center for nanoscience and nanotechnology. The activities also include Lund Nano Lab, a central and shared facility for the production of materials and components at the nanoscale. The department is also strongly engaged in undergraduate education, particularly in the civil engineering program "Technical Nanoscience" at LTH. This position is part of a research group consisting of three doctoral students with individual projects where collaboration fosters good group development. Specific Subject Description The ZEUS project focuses on promoting the development of innovative and radiation-resistant nanowire solar cells with high efficiency. While current space-tested nanowire solar cells offer approximately 15% efficiency with single bandgap cells, ZEUS aims to significantly improve this efficiency potentially up to 47% by using triple junction nanowire cells using III-V semiconductor materials. For this purpose, this interdisciplinary project will also optimize nanowire surface passivation to improve voltage and current matching. The project aims to achieve scalability by transferring nanowire solar cells to light, flexible substrates. Key objectives include: Increase the efficiency of radiation-resistant nanowire solar cells. Scale up the substrate size to 100 mm² and develop modules with a size of 1x1 cm². Reduced weight and material usage through nanowire scaling and substrate reuse. Job Responsibilities As a postdoctoral researcher, your main responsibilities include conducting research. Teaching may also be included in your duties, however, no more than one-fifth of your working time. Within the scope of the position, there is an opportunity for three weeks of higher education pedagogy training. The purpose of the position is to develop your independence as a researcher and create conditions for further professional development. You will work on the synthesis of nanowires and process them into solar cells for space applications. Characterization of the nanowires and evaluation of these in terms of external quantum efficiency (EQE) and current-voltage characterization (IV) will be part of the project. Job responsibilities include: epitaxy, cleanroom work experimental evaluation of semiconductor samples with respect to nanowires supervision of thesis work and doctoral students administration related to the above tasks Qualifications Eligibility for employment as a postdoctoral researcher requires a doctoral degree, or a foreign degree deemed equivalent to a doctoral degree, within the subject area of the position. Evidence that the qualification requirement is met must be submitted no later than when the employment decision is made. Typically, candidates should have completed their degree no more than three years before the application deadline. If there are special reasons, the doctoral degree may have been completed earlier.
