  • Solar cells with improved lifetime, passivation and/or efficiency
    Patent number: 11251315
    Abstract: A method of fabricating a solar cell can include forming a dielectric region on a silicon substrate. The method can also include forming an emitter region over the dielectric region and forming a dopant region on a surface of the silicon substrate. In an embodiment, the method can include heating the silicon substrate at a temperature above 900 degrees Celsius to getter impurities to the emitter region and drive dopants from the dopant region to a portion of the silicon substrate.
    Type: Grant
    Filed: May 18, 2020
    Date of Patent: February 15, 2022
    Assignee: SunPower Corporation
    Inventors: David D. Smith, Tim Dennis, Russelle De Jesus Tabajonda
