Abstract:
Methods and apparatuses for a dual heterojunction multijunction solar cell are disclosed. A method in accordance with the present invention comprises growing a base material for a solar cell, growing at least one dual heterojunction on the base material, and growing an emitter on the at least one dual heterojunction. An apparatus in accordance with the present invention comprises a substrate, and a first subcell, coupled to the substrate, wherein the first subcell comprises a base region, coupled to the substrate, an emitter region, and at least one dual heterojunction, coupled between the base region and the emitter region, wherein the at least one dual heterojunction has a lower bandgap than the emitter region.

Claim (Index 9):
A device, comprising:\n at least one structure comprised of a well layer contained within a region of barrier layers, wherein the well layer is comprised of a first composition comprising an alloy of AlGaAs, InGaAs, or AlGaAs and InGaAs, the barrier layers are comprised of a second composition comprising an alloy of AlGaAs, InGaAs, or AlGaAs and InGaAs, and the well layer has a lower band gap than the barrier layers; the structure is coupled between an emitter and base, wherein the emitter and base are comprised of a third composition comprising an alloy of AlGaAs, InGaAs, or AlGaAs and InGaAs, and the structure has a lower bandgap than the emitter and base; the structure is sufficiently thick that quantum confinement of a generated electron does not occur; and the structure functions to absorb light below a bandgap of the emitter and base, and to produce a current by generating electron-hole pairs as carriers that are emitted and collected at the emitter and base.
