Ge1-xSnx nanoparticles – the future of solar cells?

PhD defence, Wednesday 7 February 2024, Nicolaj Brink Søgaard

Nicolaj Brink Søgaard

During his PhD studies, Nicolaj Brink Søgaard researched the synthesis of germanium-tin (Ge1-xSnx) nanoparticles, an interesting semiconductor material with a possible future use in improving solar cells. Nicolaj Brink Søgaard studied a new way of synthesizing the Ge1-xSnx nanoparticles while characterizing the properties of the particles with X-ray diffraction and optical methods.

The new research findings contribute to the development of simple and scalable production of Ge1-xSnx nanoparticles, as the new synthesis developed circumvents the need for inert reaction techniques that typically complicate the production of Ge1-xSnx nanoparticles.

The PhD study was completed at Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
