Darius Kuciauskas: Two-photon excitation for tracking PV defects and increasing solar efficiency

NREL lab advances understanding and development of CdTe materials for photovoltaics with optical testing methods.

18 March 2016, SPIE Newsroom. DOI: 10.1117/2.3201603.03

Darius Kuciauskas received a diploma in physics (1993) from Vilnius University, Lithuania, and a doctorate in chemistry (1999) from Arizona State University. He was a Postdoctoral Scholar at California Institute of Technology, and Assistant Professor at Virginia Commonwealth University and Rowan University. Since 2010, he has been a Senior Scientist at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. His research interests are in electro-optical characterization of semiconductor materials and devices. His research goal is to develop and apply new techniques for lifetime and defect analysis in crystalline and thin-film semiconductor structures. In this endeavor, he employs time-resolved and nonlinear spectroscopy as well as photoluminescence spectral dynamics. His earlier research was on solar fuels, dye-sensitized solar cells, and two-photon and other nonlinear optical spectroscopy.
