    Abstract: Approaches for forming barrier-less seed stacks and contacts are described. In an example, a solar cell includes a substrate and a conductive contact disposed on the substrate. The conductive contact includes a copper layer directly contacting the substrate. In another example, a solar cell includes a substrate and a seed layer disposed directly on the substrate. The seed layer consists essentially of one or more non-diffusion-barrier metal layers. A conductive contact includes a copper layer disposed directly on the seed layer. An exemplary method of fabricating a solar cell involves providing a substrate, and forming a seed layer over the substrate. The seed layer includes one or more non-diffusion-barrier metal layers. The method further involves forming a conductive contact for the solar cell from the seed layer.

    Abstract: An all back contact solar cell has a hybrid emitter design. The solar cell has a thin dielectric layer (102) formed on a backside surface of a single crystalline silicon substrate (101). One emitter (103) of the solar cell is made of doped polycrystalline silicon that is formed on the thin dielectric layer (102). The other emitter (108) of the solar cell is formed in the single crystalline silicon substrate (101) and is made of doped single crystalline silicon. The solar cell includes contact holes that allow metal contacts (107) to connect to corresponding emitters (108, 103).

    Abstract: A solar cell is disclosed (200). The solar cell (200) has a front side (202) facing the sun during normal operation, and a back side (204) facing away from the sun. The solar cell comprises a silicon substrate (210), a first polysilicon layer with a region (227) of doped polysilicon on the back side of the substrate (210). The solar cell also comprises a second polysilicon layer with a second region (229) of doped polysilicon on the back side of the silicon substrate (210). The second polysilicon layer at least partially covers the region of doped polysilicon. The solar cell (200) also comprises a resistive region (224) disposed in the first polysilicon layer. The resistive region (224) extends from an edge of the second region (229) of doped polysilicon. The resistive region (224) can be formed by ion implantation of oxygen into the first polysilicon layer.
