  • Publication number: 20220173260
    Abstract: System and method of providing a photovoltaic (PV) cell having a cushion layer to alleviate stress impact between a front metal contact and a thin film PV layer. A cushion layer is disposed between an extraction electrode and a photovoltaic (PV) surface. The cushion layer is made of a nonconductive material and has a plurality of vias filled with a conductive material to provide electrical continuity between the bus bar and the PV layer. The cushion layer may be made of a flexible material preferably with rigidity that matches the substrate. Thus, the cushion layer can effectively protect the PV layer from physical damage due to tactile contact with the front metal contact.

  • Patent number: 9711671
    Abstract: System and method of providing a photovoltaic (PV) cell with a complex via structure in the substrate that has a primary via for containing a conductive material and an overflow capture region for capturing an overflow of the conductive material from the primary via. The conductive filling in the primary via may serve as an electrical contact between the PV cell and another PV cell. The overflow capture region includes one or more recesses formed on the substrate back surface. When the conductive material overflows from the primary via, the one or more recesses can capture and confine the overflow within the boundary of the complex via structure. A recess may be a rectangular or circular trench proximate to or overlaying the primary via. The recesses may also be depressions formed by roughening the substrate back surface.
