Personal Profile

Kevin L. Schulte is a scientist in the High Efficiency Crystalline PV group in the Materials Applications & Performance center at NREL.

He received BS and MS degrees in chemical engineering from Northwestern University and a PhD in chemical engineering from the University of Wisconsin-Madison. At Wisconsin, he designed and constructed a hydride vapor phase epitaxial (HVPE) growth reactor, with which he studied epitaxial growth fundamentals and defect incorporation mechanisms of III-V semiconductors.

At NREL he works to raise the efficiency and reduce the cost of III-V single and multijunction solar cells. He helped pioneer the high-throughput (>300 µm/hour) growth of III-V single-junction and tandem photovoltaic devices by dynamic-HVPE (D-HVPE), a technique with the potential to significantly reduce III-V device costs. He also investigates multijunction concentrator solar cells grown by metalorganic vapor phase epitaxy, focusing on the interplay between microstructure and performance of lattice mismatched graded buffers and devices.
