Open position for PhD/Postdoc (m/f/d)

May 19, 2026

Open for applications as of May 19, 2026

We invite applications from motivated and talented candidates for PhD/Postdoc position in the field of Pb-Sn mixed perovskite semiconductors.

Metal halide perovskites have emerged as transformative materials for next-generation optoelectronics, particularly in tandem photovoltaics and infrared photodetection. Pb-Sn mixed perovskites enable bandgap tuning into the near-infrared range, making them essential for all-perovskite tandem solar cells and infrared optoelectronic devices. However, their practical implementation faces critical challenges related to phase homogeneity, voltage losses, and operational stability. Within the framework of this DFG Emmy Noether project, we address these challenges as fundamental materials science questions. This project aims to establish structure–property–stability relationships through advanced spatially resolved characterization and rational materials design.

The successful candidate will work at the intersection of semiconductor physics, materials science, and advanced optical spectroscopy within a collaborative and internationally connected research environment. Within the framework of the project, you will:

• Fabricate and optimize Pb-Sn mixed perovskite thin films and devices for photovoltaic and optoelectronic applications and perform device characterization
• Conduct advanced optical spectroscopy measurements
• Investigate phase homogeneity, voltage losses, and degradation mechanisms under operational conditions
• Contribute to the planning and execution of project tasks and ensure their timely completion
• Present and publish research results in project meetings, peer-reviewed journals, and international conferences
• Prepare regular reports documenting scientific progress

We are looking for a curious, responsible, and ambitious candidate who enjoys engaging with fundamental scientific questions.

• Master's degree (for PhD candidates) or PhD degree (for Postdoc candidates) in Physics, Materials Science, Engineering, or a closely related field
• Solid background in semiconductor physics and optoelectronic materials
• Experimental skills in Pb-Sn based perovskites, including the ability to design experiments, operate instrumentation, and analyze data critically
• Ability to work independently while actively contributing to a collaborative research team
• Good written and spoken communication skills in English

The position is funded by a DFG Emmy Noether Grant with expected start date of late 2026.
