卢森堡大学物理学博士后（研究员）（M / F）

The University of Luxembourg is a multilingual, international research University.

The University of Luxembourg is looking within its Laboratory for Photovoltaics, Physics and Materials Science Research Unit, for a

Postdoc (Research Associate) in Physics (M/F)

to develop and characterize surface passivation layers for thin film photovoltaics

•           Ref. R-AGR-3134-10-C

•           Fixed-term contract 1 year

•           Full-time (40 hrs/week)

•           Employee status

The Laboratory for Photovoltaics is a prestigious and internationally well-connected research group working on chalcopyrite thin film photovoltaics. Our aim is to study defects in these materials and investigate and overcome limitations in state-of-the-art thin film solar cells. We closely collaborate with research institutes and companies all over the world.

The project aims to study the fundamental behavior of dielectric passivation layers on chalcopyrite Cu(In,Ga)Se₂ absorbers. Electronic defects within the absorber or at the interfaces in the solar cell, and to which extent these can be tailored by applying a passivation layer, are a major focus of our investigations. Among other techniques, we will employ advanced optical characterization using photoluminescence (PL) to study these defects. 

Tasks:

 The successful candidate will

• be responsible for advanced optical characterization of absorber films and passivated devices by low-temperature and room-temperature photoluminescence (PL), including calibrated PL and time-resolved PL,
• deposit chalcopyrite thin film absorbers by physical vapor deposition (PVD),
• provide support with electrical characterization (admittance spectroscopy, capacitance-voltage, current-voltage),
• contribute to the interpretation of all experimental results in the project, including optical, electrical, chemical and structural,
• present the results in high impact journals and at international conferences.

Although the focus of the open position is on PL characterization, involvement in all aspects of the project is possible and encouraged.
