You will join an international collaboration with TalTech, performing synthesis, device fabrication, and advanced optoelectronic characterization to push performance under realistic illumination conditions.

The position includes a research stay at TalTech, supervision of MSc/BSc projects, and dissemination through conferences and journals as part of DTU’s Alliances

Qualifications

• Strong academic background in physics, chemistry, materials science, nanotechnology or related field.
• Prior knowledge of semiconductor physics and photovoltaics would be valuable.
• Experience with thin-film materials, solar-cell fabrication, optoelectronic characterization, or indoor photovoltaics would be valuable.

Responsibilities

• Develop high-efficiency Sb2S3 thin-film solar cells by engineering device architectures and interfaces to enhance charge collection while minimizing recombination and voltage losses under indoor illumination.
• Characterize solar cells under different LED spectra, light intensities, and illumination conditions relevant to realistic indoor environments.
• Investigate defect states, interface recombination, and open‑circuit voltage losses, including advanced electrical characterization during a research stay at TalTech.
• Develop and characterize series‑connected indoor photovoltaic mini‑modules for battery‑free IoT applications.
• Supervise and contribute to MSc/BSc student projects.
• Document and disseminate the research through scientific publications and international conference contributions
• You will undertake a research stay at TalTech and collaborate with researchers from both universities.
