Team Members 
Principal Investigator: Aaron Ptak
Entrepreneurial Lead: David Young
Industry Mentor: Sally Hatcher

Technology Description

Team HALO will explore a business model for NREL's research on dynamic hydride vapor phase epitaxy (D-HVPE) to grow high efficiency III-V solar cells at a greatly reduced price compared with the incumbent technology of metal organic chemical vapor deposition (MOCVD). D-HVPE produces devices with excellent bulk material quality, and sharp, well-passivated interfaces at high deposition rates (> 1 µm/min), using low-cost bulk metal and HALOgen chemistry.
