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.

在实验验证方面，本实验室将砷化镓太阳电池由砷化镓基板转移至铜基板上，在基极厚度1.5 μm、AM 1.5G、以及元件未披覆抗反射膜的条件下，短路电流密度可由12.6 mA/cm2提升至13.82 mA/cm2，增加9.7%，而转换效率则可由7.91%提升为8.53%，这结果显示当砷化镓太阳电池基极底部镀有金属反射层时，的确能适度地提升太阳电池的短路电流密度及转换效率。
