    Starting dateNot Specified


    Two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.


    The assessment of the candidates will be made by the main supervisor, Professor Jens Wenzel Andreasen in collaboration with the co-supervisors Professor Henning Friis Poulsen (DTU Physics). Professor Morten Madsen (University of Southern Denmark), Professor Anders Østergaard Madsen (University of Copenhagen), and Head of Section Luise Theil Kuhn


    • Your focus will be on the 3D mapping of grains, identification of secondary phases, and the distribution of strain and defects through mass refinement of crystal structures.
    • The candidate will carry out 3DXRD experiments on materials, synthesized and processed at SDU or DTU, at large scale facilities (synchrotrons) and analyse the resulting 3D crystallographic data to establish 3D models of crystalline texture and phase conformation.
      As the direct outcome of the project, we aim to
    • Acquire 3D data that allow us to quantify crystalline domain size, texture and defect concentrations with high spatial resolution and grain boundary relations in bulk absorber layers and at interfaces to the bounding electrodes.
    • Image the 3D spatial distribution and strain state of the crystalline phases in polycrystalline solar cells.
    • Show the dynamical degradation effects on micro- and nanocrystalline morphology by in situ 3DXRD on a 3rd generation solar cell.

    How to Apply?

    To apply, please open the link “Apply online”, fill out the online application form, and attach all your materials in English in one PDF file.

    Documents Required

    Applications must be submitted as one PDF file containing all materials to be given consideration. The file must include:

    • A letter motivating the application (cover letter)
    • Curriculum vitae
    • Grade transcripts and BSc/MSc diploma
    • Excel sheet with translation of grades to the Danish grading system (see guidelines and Excel spreadsheet here)

    About the project/department

    In this project, the candidate will use 3D X-ray diffraction methods (3DXRD) that enable us to quantify the texture and strain distribution of crystalline phases in 3rd generation solar cells in the completed, functioning devices. The methods will primarily be applied to inorganic materials systems, although feasibility tests on organic materials is also foreseen.

    The materials systems will be chosen to connect with new work on all-oxide tandem thin film photovoltaic devices, a sub-project which is a part of a larger project PIloT, where the aim is to develop all-oxide thin film photovoltaic (PV) devices for the Internet of Things (IoT). A focus here is on controlling microstructure, chemical composition and interfaces during the metal oxide thin film growth process. The work includes synthesis and integration of metal oxide electron and hole transport layers, as well as of active absorber layers.

    The project you apply for, is part of the Centre of Excellence on hard materials, SOLID (www.solid.dtu.dk), which has focus on research using the state-of-the-art large scale facilities, ESS and MAXIV for neutron and synchrotron imaging. You will thus have interaction with a large network of PhD students working with imaging, across Denmark.


    • The PhD project will be conducted as a collaboration between the Section for Imaging and Structural Analysis (DTU Energy), the Section for Neutrons and X-rays for Materials Physics (DTU Physics), Mads Clausen Institute and SDU NanoSYD (SDU, University of Southern Denmark), and Manufacturing and Materials (Department of Pharmacy, University of Copenhagen).
    • All interested candidates irrespective of age, gender, race, disability, religion or ethnic background are encouraged to apply.
    • If you are applying from abroad, you may find useful information on working in Denmark and at DTU at DTU – Moving to Denmark.
