Adam Halverson - Postdoc
Adam Halverson’s scientific career began at Reed College where he received his BA in Physics in 2000 working under Dr. Nicholas A. Wheeler. After a year in the semiconductor industry, he matriculated at the University of Oregon in the physics department, ultimately joining the lab of Dr. J. David Cohen. In the Cohen lab, he used sophisticated measurements to study the electronic properties of disordered semiconductor thin films, particularly those used in thin-film solar cells. Characterization methods used included drive-level capacitance profiling (DLCP) and transient photocapacitance and transient photocurrent spectroscopies (TPC/TPI). These techniques were used to study the metastable effects of reverse bias stressing in CuInGaSe2 thin-film solar cells, as well as the effects of sulfur alloying in pentenary Cu(InxGa1-x)(SySe1-y)2 thin-film solar cells. These studies were focused on understanding the failure of the open-circuit voltage to scale with the bandgap.
Upon completion of his Ph.D. in Physics in 2007, Dr. Halverson joined the lab of Dr. Arthur Frank as a postdoc in the Chemical Science and Nanoscience group at NREL. His work at NREL involves characterizing nanoporous and nanostructured TiO2 metal-oxide thin-films. These films are commonly used as the electrodes in dye-sensitized solar cells.
