Abstract
A stacked multi-junction solar cell comprising a stack composed of a bottom subcell, at least one middle subcell, and a top subcell, wherein each subcell has an emitter and a base at least the top subcell is made of a III-V semiconductor material or includes a III-V semiconductor material, and the emitter of the top subcell includes a superlattice.
Claims15
A stacked multi-junction solar cell comprising:
- a stack formed of a bottom subcell, at least one middle subcell, and a top subcell,
- wherein each subcell has an emitter and a base,
- wherein at least the top subcell is formed of a III-V semiconductor material or includes a III-V semiconductor material,
- wherein the light passes through the top subcell to the other subcells, and
- wherein the emitter of the top subcell includes a superlattice or is formed substantially of a superlattice structure.
