In our experimental results, we have transferred the GaAs solar cells from GaAs substrates onto the mirror-coated copper substrates with the base layer thickness of 1.5 μm. The photovoltaic performance of the orginal GaAs solar cell on a GaAs substrate was also measured. Under AM1.5G and without anti-reflective coatings conditions, it is found that the Jsc can increase from 12.6 mA/cm2 to 13.82 mA/cm2, while the conversion efficiency can improve from 7.91% to 8.53%. As a result, the enhanced Jsc and η data of the GaAs solar cells can be contributed by the AuGe/Au mirror between the GaAs solar cell and copper substrate.
