  • Modular, glass covered solar cell array
    Patent number: 6407327
    Abstract: A radiation tolerant solar cell array module which can be efficiently assembled into a larger solar panel to generate power for a spacecraft the module includes at least first and second single-crystal solar cells. The first and second solar cells have front sides and back sides. At least one of the solar cells has a shallow junction N on P structure. A first contact is formed on at least the back side of the first solar cell. A second contact formed on at least the back side of the second solar cell. A conductor is in electrical communication with the first contact and the second contact. A substantially transparent ceria-doped cover overlays at least a portion of each of the solar cells. The cover remains substantially transparent when exposed to an AM0 space radiation environment. A substantially transparent adhesive is situated between the cover and the solar cell portions. The adhesive remains substantially transparent when exposed to a space radiation environment.

  • Solar cell having an integral monolithically grown bypass diode
    Patent number: 6359210
    Abstract: The present invention is directed to systems and methods for protecting a solar cell. The solar cell includes first solar cell portion. The first solar cell portion includes at least one junction and at least one solar cell contact on a backside of the first solar cell portion. At least one bypass diode portion is epitaxially grown on the first solar cell portion. The bypass diode has at least one contact. An interconnect couples the solar cell contact to the diode contact.

  • Solar cell having a front-mounted bypass diode
    Patent number: 6326540
    Abstract: An efficient method of interconnecting a solar cell having at least two front surface contacts with a diode mounted on a front surface of the solar cell includes the act of forming at least a first recess on a front surface of the solar cell. A first solar cell contact is formed on the front surface in the first recess. A second solar cell contact is formed on the front surface. At least a first bypass diode is positioned at least partly within the recess. The bypass diode has a first diode contact and a second diode contact. The first solar cell contact is interconnected with the first diode contact. The second solar cell contact is interconnected with the second diode contact.
