Abstract:
1. A solar cell assembly, comprising: a germanium (Ge) substrate; at least a first solar cell, coupled to a first side of the Ge substrate, the first side of the Ge substrate to be exposed to light such that the at least first solar cell generates a current when exposed to the light; and two Schottky barrier bypass diodes connected in series, the two series connected Schottky barrier bypass diodes being connected in anti-parallel with the at least one solar cell, and the two series connected Schottky barrier bypass diodes being monolithically integrated with the Ge substrate and formed in a single recess or on a surface of a second side of the Ge substrate, the second side of the Ge substrate being substantially opposite the first side of the Ge substrate, such that the two series connected Schottky barrier bypass diodes reduce the leakage current in the solar cell assembly.
