Post Graduate Fellows

IEC Postgraduate Fellows

Limited Term Researchers are academics or professionals whose project scope is of a specific nature. The term of the appointment is typically based on the fulfillment of that specific project.

The IEC is please to collaborate with the following researchers:

Dominik Berg

Dominik Berg

Dominik M. Berg is a Limited Term Researcher at the University of Delaware's Institute of Energy Conversion (IEC). He studied Physics at the University of Bonn, Germany, and at the Australian National University (ANU) in Canberra, Australia, before obtaining his "Diplom"/master's degree in physics from the University of Bonn in 2008. The research for his master's degree concerned organic field effect transistors based on quinacridone. In 2012, Dominik received his Ph.D. in Physics from the University of Luxembourg. His doctoral research was focused on understanding the formation of high quality Cu2ZnSnS4 absorber layers for high efficient thin film solar cells, and on the discrimination of possible secondary phases of the Cu-Zn-Sn-S system from Cu2ZnSnS4. As part of the research for his Ph.D., a novel annealing approach to form Cu2ZnSn(S,Se)4 thin films was introduced and patented. Dominik joined the IEC in 2012, where his research focuses on the development of the selenization/sulfization of metal precursors for the Cu(In,Ga)(Se,S)2 thin film formation, as well as on the incorporation of Na into the Cu(In,Ga)(Se,S)2 thin film absorber layer.

Jes Larson

Jes Larsen

Jes Larsen is a Limited Term Researcher at IEC. He has a multidisciplinary background with a master's degree in nanomaterials obtained at the University of Aalborg, Denmark in 2008. The research for his master's degree concerned interfaces in stone wool composite materials.  Jes received his Ph.D. degree in Physics in 2011 from the University of Luxembourg. His doctoral research was focused on inhomogeneities in epitaxial copper indium gallium diselenide (CIGS) thin films using photoluminescence as a primary characterization technique. At IEC he will do research on CIGS devices with a superstrate structure.

JinWoo Lee

JinWoo Lee

JinWoo Lee is a Limited Term Researcher at the Institute of Energy Conversion at the University of Delaware. JinWoo received his Ph.D. in Physics from the University of Oregon and prior to that studied at Yonsei University in Seoul, Korea for his bachelor's and master's degrees in Physics. He has prior experience as a senior research engineer. At IEC he will do research on a high efficiency project with Ag alloy CIGS solar cells.

James Mutitu

James Mutitu

James Mutitu is a Limited Term Researcher at the Institute of Energy Conversion having recently earned his Ph.D. in Electrical Engineering at the University of Delaware.  His research focuses on light trapping in thin film solar cells.
