Professional Profile: My name is Jimmy Melskens. I obtained my BSc, MSc, and PhD degrees in Electrical Engineering from Delft University of Technology. At TNO I am working in the crystalline silicon solar cell team with a special focus on the fabrication and characterization of thin layers that enhance the solar cell performance, in particular so-called transparent passivating contacts. The focus of my doctoral thesis was the fabrication and characterization of hydrogenated amorphous silicon (in the context of thin-film silicon solar cells) to gain a better understanding of the defects in this material especially. After completing this project, I joined Eindhoven University of Technology in 2014 as a postdoctoral researcher at the Department of Applied Physics. In that position I was primarily working on the development of surface passivation materials by atomic layer deposition for crystalline silicon solar cells. Additionally, I am co-owner and CTO of Delft Spectral Technologies, a startup that is aiming to commercialize advanced optoelectrical characterization equipment for researchers in the field of solar cells. Outside work I like swimming, cycling, cooking, and traveling (when the conditions in the world allow this again of course).
