Patent number: 10903786Abstract: In one embodiment, harmful solar cell polarization is prevented or minimized by providing a conductive path that bleeds charge from a front side of a solar cell to the bulk of a wafer. The conductive path may include patterned holes in a dielectric passivation layer, a conductive anti-reflective coating, or layers of conductive material formed on the top or bottom surface of an anti-reflective coating, for example. Harmful solar cell polarization may also be prevented by biasing a region of a solar cell module on the front side of the solar cell.Type: GrantFiled: November 20, 2018Date of Patent: January 26, 2021Assignee: SunPower CorporationInventors: Richard M. Swanson, Denis De Ceuster, Vikas Desai, Douglas H. Rose, David D. Smith, Neil Kaminar
