  • Reverse heterojunctions for solar cells
    Patent number: 9153724
    Abstract: In a solar cell having one or more subcells, at least one subcell is provided with a reverse heterojunction, the reverse heterojunction being formed with an emitter and an adjacent base, wherein the emitter has a band gap that is at least 10 meV lower than that of the adjacent base in order to reduce sheet resistance of the emitter and/or increase the subcell current with minimal effect on the open-circuit voltage. Because of the increase in current, the decrease in emitter sheet resistance, and relatively unchanged open-circuit voltage of the subcell, the efficiency of a solar cell employing one or more subcells with reverse heterojunctions is enhanced.
