    Abstract: Approaches for forming solar cells with a converted seed layer as a buffer material and the resulting solar cells are described. In an example, a method of fabricating a solar cell includes converting regions of a seed layer disposed on a plurality of p-n junctions of the solar cell to form a pattern of interdigitated converted regions. The converted regions are configured to electrically insulate non-converted regions of the seed layer from each other and provide a barrier to a laser that is, in fabricating the solar cell, directed towards the seed layer such that the barrier substantially avoids degradation of at least the plurality of p-n junctions from the laser.

    Abstract: Approaches for fabricating one-dimensional metallization for solar cells, and the resulting solar cells, are described. In an example, a solar cell includes a substrate having a back surface and an opposing light-receiving surface. A plurality of alternating N-type and P-type semiconductor regions is disposed in or above the back surface of the substrate and parallel along a first direction to form a one-dimensional layout of emitter regions for the solar cell. A conductive contact structure is disposed on the plurality of alternating N-type and P-type semiconductor regions. The conductive contact structure includes a plurality of metal lines corresponding to the plurality of alternating N-type and P-type semiconductor regions. The plurality of metal lines is parallel along the first direction to form a one-dimensional layout of a metallization layer for the solar cell.

    Abstract: A method for fabricating a solar cell is disclosed. The method can include forming a dielectric region on a surface of a solar cell structure and forming a first metal layer on the dielectric region. The method can also include forming a second metal layer on the first metal layer and locally heating a particular region of the second metal layer, where heating includes forming a metal bond between the first and second metal layer and forming a contact between the first metal layer and the solar cell structure. The method can include forming an adhesive layer on the first metal layer and forming a second metal layer on the adhesive layer, where the adhesive layer mechanically couples the second metal layer to the first metal layer and allows for an electrical connection between the second metal layer to the first metal layer.
