Popis: Two window layer materials, Al0.51In0.49P (Eg = 2.3 eV) and Ga0.51In0.49P (Eg = 1.88 eV) were compared for gas-source and solid-source MBE grown GaAs and Ga0.84In0.16As0.68P0.32 (Eg = 1.55 eV) solar cells. Due to the wider band-gap of Al0.51In0.49P, the increased spectral response was observed for both GaAs and Ga0.84In0.16As0.68P0.32 material based solar cells. In the case of the GaAs cells, the short-circuit current density was observed to Increase from 32.5 mA/cm2 to 34.4 mA/cm2 with the Al0.51In0.49P window layer at AM0. Similar improvement was observed for the Ga0.84In0.16As0.68P0.32 solar cells.
