Doing a PhD research on improving Cu(In,Ga)(S,Se)2-based thin-film solar cells at the Karlsruhe Institute of Technology
At the moment I am doing my PhD research at the Karlsruhe Institute of Technologie. For those interested, a brief introduction about myself:
Already as a child I have been fascinated by how the world works and what everything around us is made of. The physical world and the advanced technology in it have played a central role in my decision-making during my studies. My passion for advanced technology expressed itself by my choice for the Bachelor in Aerospace Engineering at the University of Technology in Delft.
During this studies I realized that I am often very curious for the physical principles that the engineering techniques rely upon, so I decided to switch to the Master Applied Physics. Because I have a strong interest in elementary particles and radiation, I choose a specialization in the area of radiation.
For my Master thesis I was able to conduct experiments in Karlsruhe at the Institute for Transuraniumelements (ITU) of the European Commission. Here I did research into the aerosols that are created in radiological dispersion events (or devices also known as “Dirty Bombs”).
I am now doing a PhD research with a focus on improving Cu(In,Ga)(S,Se)2-based thin-film solar cells and modules. I am responsible for investigating the chemical and electronic structure of the absorber surfaces and interfaces (e.g., the absorber/buffer heterojunction) using electron and soft x-ray spectroscopies. Expected results are the determination of band alignments at the investigated interfaces, the identification of secondary elements/phases, and/or information on diffusion and intermixing processes.
