  • High current burn-in of solar cells
    Patent number: 11133778
    Abstract: A method of high reverse current burn-in of solar cells and a solar cell with a burned-in bypass diode are described herein. In one embodiment, high reverse current burn-in of a solar cell with a tunnel oxide layer induces low breakdown voltage in the solar cell. Soaking a solar cell at high current can also reduce the difference in voltage of defective and non-defective areas of the cell.
    Type: Grant
    Filed: February 27, 2018
    Date of Patent: September 28, 2021
    Assignee: SunPower Corporation
    Inventors: Michael J. Defensor, Xiuwen Tu, Junbo Wu, David D. Smith
