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.
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.
