– Post-doc (NTNU)
October 2014 – January 2017
In this position, I studied potential intermediate band solar cells (IBSCs). In particular, I worked on fabrication and characterization of deep level intermediate band materials, namely doped ZnS and Si and Cu2O. I also studied reduced MoO3 containing oxygen vacancy defects resulting in formation of energy levels/state within the band-gap. My contributions were pulsed laser deposition of thin films, pulsed laser melting of implanted semiconductors, fabrication of solar cell devices, and characterization of thin films and solar cell devices using various relevant techniques. The outcomes of the research were published in multiple conferences and over seven journal papers.
My duties also include assisting in the training and supervision of PhD and final year project or master students.
In addition to the research activities, I have been the course coordinator and the lecturer for the master level course “Energy and Environmental Physics” at NTNU.
– Visiting Scholar (IES-UPM)
March 2016 – July 2016 (5 months)
During the research visit, I joined the group of Prof. Antonio Martí, the inventor of intermediate band solar cells, at the Solar Energy Institute of the Technical University of Madrid. We investigated the voltage preservation and the two-photon effect in the solar cells that I fabricated at NTNU earlier in 2016. The outcomes were published in Sol. Energy Mater Sol. Cells journal.
