Offer Description

At the University of Göttingen -Public Law Foundation-, Institut für Materialphysik, there is a 

PhD Position (all genders welcome) Entgeltgruppe 13 TV-L/66% to be filled. 

The starting date is as soon as possible. The position is limited to 31 December 2027. A working time of 75% (29.85 hours) is planned for the 2-3rd year of the contract.

“Gradient bandgap engineering in oxide perovskites for use in tandem solar cells” as part of the ‘FuturePV’ „Grundlagen für Photovoltaik-Technologien der Zukunft“  - Graduiertenkolleg - Lower Saxony Ministry of Science and Culture.

Project:
This subproject of ‘FuturePV’ aims to develop tuneable oxide/oxynitride perovskite thin films for use in tandem solar cells as a charge-selective contact as well as a stable n-type absorber. The primary goal is to use the strategic approach of gradient bandgap engineering to modify the transparent conducting perovskite oxides to i) an oxynitride n-type semiconductor as well as ii) to a ferroelectric layered photo absorber with conducting layers. This project will be implemented within the groups of Prof. Jasnamol Palakkal and Prof. Christian Jooss.    

Your tasks and duties:

You will grow epitaxial thin films of a transparent conducting perovskite oxide and its oxynitrides on various perovskite oxide substrates using a hybrid molecular beam epitaxy-pulsed laser deposition (MBE-PLD) technique. Careful study of the structure of this film by XRD, XPS, and TEM (collaboration with Prof. M Seibt / Dr. T. Meyer, University of Göttingen. See Ph.D. advt. 74378) and analysis of the electric transport and optical conductivity will allow to establish a comprehensive structure-property relationship of this new highly promising material class. Furthermore, the photovoltaic effect of niobite single junctions and its performance in a tandem cell will be investigated by systematic spectrally resolved and temperature-dependent photovoltaic measurements. Active collaboration with other project partners of ‘FuturePV’ from various research institutes in Lower Saxony is expected.

Your profile:

 Recently obtained Master’s degree in physics, materials sciences, or closely related subject areas
 Communication skills in English are required. Good German language skills are desirable
 You are a team worker and self-motivated to attain project goals

Preferred Experiences (experiments, data collection, and analysis):

 Thin film growth by pulsed laser deposition/molecular beam epitaxy

 Structural characterization of materials by XRD, XPS, etc.

 Optical and photovoltaic characterization

Please upload your application in one PDF file, including the usual documents, by 11. March. 2024 on the application portal of the university using this link:
