Research output: Contribution to conferencePaper


In this work we present solar cells grown via hydride vapor phase epitaxy (HVPE) in NREL's dynamic HVPE reactor. We show single junction GaAs and GaInP solar cells with efficiencies as high as 25.5% and 15.2% respectively, and dual junction solar cells with an efficiency of 24.9%.
