Catalytic hydrogenation for improvement of GaAs/Ge solar cell efficiency
Hydrogen passivation on MOCVD grown p-GaAs epilayers on Ge substrate have been studied by plasma and catalytic hydrogenation and the results were compared. The conversion efficiency of the GaAs/Ge solar cells was found to increase by similar to10% after catalytic hydrogenation at AM1.5. This increase in efficiency is probably due to passivation of surface dangling bonds. (C) 2002 Elsevier Science B.V. All rights reserved.
