Researcher – Surface and Quantum Confinement Effects in Pyrite Solar Cells Materials - At the Ångström Laboratory, Department of Engineering Sciences, Division of Solid State Physics. Full-time employment for two years with start in January 2018 or by agreement.
Research on nanomaterials relevant for energy and environmental applications are well established at the Department of Solid State Physics at the Ångström Laboratory. In many cases, it is the electronic properties of the materials that provide the desired functionality. Semiconductor materials is the class of materials currently used in a variety of solar technologies, such as conventional Si solar cells and thin film solar cells. Common to these is that electronic excitations and electron transport is used in each application where losses to surface or bulk defect states in the materials reduces efficiency. The catalysis and solar energy group at the Division of Solid State Physics is working with fundamental understanding and development of efficient electrochromic, catalytic and super absorbing solar energy materials based on nanomaterials and thin film technology.
Project Description: The main goal of the project is to investigate ultrathin Pyrite layers for application in super absorbing solar cells where fundamental questions about the surface states and charge carrier mobility will be addressed. The project is of a fundamental nature and will be implemented in close collaboration with the division of physical chemistry where full solar cell device assembly and device characterization are available. The project involves manufacturing of ultrathin pyrite (FeS2) films, measurements and analysis of electronic and optical material properties in the films with special attention to increase the photovoltage in the system. In particular, band gap opening with doping and quantum confinement will be investigated with photo-electrochemical and photo-physical techniques. The optimal n- and p-type charge carrier contact materials for the system will also be investigated. Resonant and non-resonant Raman spectroscopy, spectroscopic ellipsometry, Scanning Nearfield Optical Microscopy (SNOM) photoluminescence (PL) and other scanning PL techniques will be central in the project. The later part of the project will also include fabrication and characterization of complete photovoltaic devices. The group is fully equipped with the relevant characterization techniques but some of the experiments will also be performed on large-scale international synchrotron facilities in co-operation.
Qualifications: PhD in physics, materials chemistry, physical chemistry or related area. Experience of electrical and optical characterization methods for photoactive materials and previous experience in manufacturing of thin films or photoactive nanomaterials relevant for the project are meriting. The applicant should have good communication skills and speak and write good English.
Application: Applications from qualified candidates should include a brief description of research interests and relevant experience, a CV and a list of publications. We prefer that you provide names and contact details of at least two persons that have offered to act as reference for you, with a clear indication of their relationship to you.
