A Path to III-V Photovoltaic Cost Reduction Combining GaAs (211) Spalling with Halide Vapor Phase Epitaxy

Research output: NLRPresentation

Abstract

This presentation is an overview of the following, Spalling on 211 oriented wafers produces flat surface without faceting: 1) Demonstrated spall on entire 2" wafer; 2) GaAs and GaInP grown on 211 wafers by HVPE; and 3) Promising cell with VOC=1.02 V and IQE-1. Next steps: 1) Grow cell on spalled wafer and 2) Growth studies to improve material and cell on 211 substrates.
