You should apply for this position if you are passionate about solutions for the transition to a society running on sustainable energy. Solar energy will play a significant role in this and there is a need for cheap, robust and environmentally friendly solar cells to accommodate the constantly growing energy demand. If you engage with us in this leading edge materials research effort, with strong connection to fundamental physics, you will break new ground in the high-profile field of organic photovoltaics.
The position is part of a new national project supported by the Independent Research Fund Denmark, DFF FTP – Entangled PolaritonIC states for improved energy and charge transfer in non-fullerene Organic PhotoVoltaics, EPIC-OPV. The project is carried out in close collaboration between Section for Imaging and Structural Analysis (DTU Energy) and Mads Clausen Institute and SDU NanoSYD (SDU, University of Southern Denmark) together with Paris-Sorbonne University as external partner.
The overall project objective is to investigate strong light-matter coupling in special architecture non-fullerene based organic photovoltaic devices, designed to study the role of such effects on the fundamental energy and charge transfer processes taking place in OPV devices. In addition to this PhD position, a Post Doc will be working in parallel on the project at the SDU partner, under supervision of Prof. Morten Madsen.

Responsibilities and qualifications
You will be working with structural, morphological, photophysical and device characterization of solar cell devices that are designed to clarify whether the effect of strong light-matter coupling gives a significant contribution to the performance of solar cells based on non-fullerene acceptors.
State-of-the-art characterization is required to unequivocally assign the mode of energy transfer and to verify the performance enhancement in optical cavities and solar cells.
To create efficient optical cavities and unambiguously confirm the contribution of different modes of energy transfer, we must determine and control the multilayer structures with high accuracy. This holds for structure at the molecular level all the way up to thickness, smoothness and planarity of the individual layers. The methodologies that will be employed include:
- Grazing Incidence Wide and Small Angle X-ray Scattering (GIWAXS/GISAXS)
- X-ray reflectometry
- Photoelectron spectroscopy
- Transient photoluminescence using a femtosecond laser and streak camera setup
Device performance testing will be investigated by correlating the results of transient photoluminescence with measurements of
- Current-voltage (IV) curves
- External quantum efficiency
Experience and qualifications with X-ray scattering methods is a requirement.
You must have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.
Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.
The assessment of the applicants will be made by a recruitment committee consisting of main supervisor Professor Jens Wenzel Andreasen, co-supervisor Professor Morten Madsen, and Head of Section Luise Theil Kuhn.
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.
Salary and appointment terms
