We report on molecular beam epitaxy grown InAs/GaAs quantum dot solar cells incorporating thin-film configuration with back surface reflectors. External quantum efficiency measurements reveal two times higher current generation for the quantum dots with the thin-film solar cell with the back reflector compared to a standard reference solar cell without back reflector. A high open-circuit voltage of 0.884 V is demonstrated. Furthermore, the benefits of using more advanced designs for a back reflector employing pyramidal diffraction gratings are discussed.
