Satisfying the demand for renewable, environmentally friendly energy is one of the urgent grand challenges. Photovoltaics (PV) is definitely one of the answers to this challenge. Since the efficiency of single material PV cells is approaching fundamental limits a major challenge in photovoltaics today is to improve efficiency in order to reduce the levelized cost of electricity below that of fossil fuels. Fortunately, in tandem solar cells far higher efficiency is possible, and this PhD project is part of a larger effort at DTU Nanotech and DTU Fotonik, which aims at developing the necessary technology to realize the potential for enhanced efficiency by integrating a Cu2ZnSnS4 (CZTS) solar cell on top of a Silicon solar cell.

Responsibilities and tasks
The ultimate goal of the overall project is to develop technology for a CZTS-Silicon tandem solar cell. This entails an improvement of CZTS single cell technology to enhance the efficiency, development of a suitable silicon bottom cell, and solving issues related to integration of the two cells.

This PhD project will be involved in all three main topics by

  • providing some of the front and back end films for the CZTS cell, participation in characterization of the CZTS films, whereas the actual synthesis of CZTS will mostly be done by other project partners
  • developing and characterizing the bottom silicon cell
  • studying and solving the integration issues, i.e., some kind of tunnel junction is necessary at the interface between the two cells, and in addition the silicon cell must be protected against in-diffusion of metals from the CZTS.     

Qualifications
Candidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in engineering.

Successful candidates should have experimental cleanroom experience and preferably past experience with solar cell technology and characterization of thin film materials.

Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide .

Assessment
The assessment of the applicants will be made by Professor Ole Hansen and Dr. Andrea Crovetto.

We offer
We offer an interesting and challenging job in an international environment focusing on education, research, scientific advice and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world.

Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.

The project will be carried out at DTU Nanotech in close cooperation with DTU Fotonik at Risø; thus part of the time will be spent at Risø.

Further information
Further information may be obtained from Professor Ole Hansen, tel.: +45 4525 5715.
