According to the simulated results, it was found that the incident light was not fully absorbed in the solar cell due to a thinner base layer. The un-absorbed incident light could be further reflected by a AuGe/Au mirror layer and absorbed again by the base layer. Thus the disadvantage of the GaAs thin-film cell with a thinner base layer could be solved by the additional reflection from the AuGe/Au mirror with a high reflectivity within 800~1000 nm wavelength. Moreover, the external quantum efficiency in the long wavelength region and short current density were also increased.
