Overview

Personal Profile

ResearchGate

Edgard Winter da Costa is working at NREL on hydride vapour phase epitaxy (HVPE) of III-V and IV semiconductor materials for solar cells. His research focus is on the growth of high efficiency III-V solar cells on reused substrates as well as on the growth of germanium on spalled germanium substrates for substrate reuse purposes. During his doctorate at the Fraunhofer Institute for Solar Energy Systems ISE and at Pontifical Catholic University of Rio de Janeiro, he worked with the metalorganic vapour phase epitaxy of III-V semiconductor materials on unpolished  germanium substrates as wells as on porous germanium and silicon-germanium substrates with the objective of reducing costs and reuse the substrates.
