What will you be doing?

The Integrated Devices and Systems group at University of Twente and TNO/Solliance (The Netherlands) are looking for an excellent candidate for an open post doc position on post mortem analysis on photovoltaic (PV) modules.

The qualification and attractiveness of a PV module is primarily determined by its performance, costs and lifetime. During its operational lifetime, a product will be exposed to external stresses like humidity, temperature, electrical fields and illumination. These factors normally lead to a gradual decrease of the performance and in some cases to (unexpected) breakdown and power loss. For large scale implementation of PV modules, it is therefore crucial to understand, prevent and predict degradation. In recent decades, many studies have focused on the stability of PV modules exposed to accelerated lifetime tests (ALT) or field exposure. Nowadays, a additional new set of possible research devices become available: modules that have degraded during normal field operation.

In this project, we will develop ‘post mortem’ analysis for PV modules, that have degraded in the laboratory or in the field. The focus will lie on thin film CIGS modules, while other PV technologies can also be included. First experiments within Solliance have yielded a method to bring solar cells from field failed modules back to life. You will further develop methods to obtain high quality solar cells from degraded modules and determine occurred degradation mechanisms.

In this project, you will use a wide range of analysis techniques, like SEM-EDX, photoluminescence, electroluminescence, lock in thermography, Raman, X-Ray Fluorescence, X-Ray Diffraction, microscopy, four point probe current-voltage and quantum efficiency measurements. You will be in charge of the experimental work, data interpretation and oral and written reporting.

You will work closely together with both researchers and engineers from Solliance and colleagues within ECN part of TNO, and with researchers within the Integrated Devices and Systems group at the University of Twente. The majority of your work will be integrated within the shared research program of Solliance, in which 200+ scientists from companies, universities and research institutes collaborate to develop and integrate thin film PV products. You will officially be mentored by two supervisors (Dr. Mirjam Theelen from Solliance, TNO and Prof. Dr. Jurriaan Schmitz from Integrated Devices and Systems, University of Twente).

What do we require of you?

The successful candidate should have:

* A Ph.D. degree in Material Science or in a closely related discipline (or expect to graduate very soon)
  • Proficiency with a large range of analysis techniques
  • Experience in photovoltaics (CIGS) and/or reliability will be regarded as a bonus
* The drive to tackle a complex problem within a dynamic environment. The successful candidate has excellent team-working and communication skills.

* A dynamic, pro-active character and excellent communication skills, as well as proven capabilities in publication and presentation.

* The ambition to excel in research.

What can you expect of your work situation?

The University of Twente:
We stand for life sciences and technology. High tech and human touch. Education and research that matter. New technology which leads change, innovation and progress in society. The University of Twente is the only campus university of the Netherlands; divided over five faculties we provide more than fifty educational programmes. We have a strong focus on personal development and talented researchers are given scope for carrying out groundbreaking research.

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status or disability status. Because of our diversity values we do particularly support women to apply.

The faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) comprises three disciplines that shape Information and Communication Technology. ICT is more than communication. In almost every product we use mathematics, electronics and computer technology and ICT now contributes to all of societies' activities. The faculty works together intensively with industrial partners and researchers in the Netherlands and abroad and conducts extensive research for external commissioning parties and funders. The research which enjoys a high profile both at home and internationally, has been accommodated in the multidisciplinary research institutes: Mesa+ Institute, TechMed Centra and Digital Society Institute.

The IDS group is part of the Faculty of Electrical Engineering, Mathematics and Computer Science and the MESA+ Institute for Nanotechnology. MESA+ is the largest research institute of the University of Twente. The institute trains graduate students and PhD-students and conducts research in the fields of nanotechnology, microsystems, materials science and microelectronics. Unique of MESA+ is its multidisciplinary composition.
