  • Patent number: 9871150
    Abstract: Methods of fabricating a solar cell including metallization techniques and resulting solar cells, are described. In an example, a first and second semiconductor regions can be formed in or above a substrate, where a separation region is disposed between the first and second semiconductor regions. A protective region can be formed over the separation region. A first metal layer can be formed over the substrate, where the protective region prevents and/or inhibits damage to the separation region during the formation of the first metal layer. Conductive contacts can be formed over the first and second semiconductor regions.

  • Patent number: 9859452
    Abstract: Methods are provided for fabricating photovoltaic cell contacts, which include: providing a block copolymer layer above an electrical contact layer of the photovoltaic cell, the block copolymer layer being self-assembled by phase segregation to include multiple structures of a first polymer material surrounded, at least in part, by a second polymer material; selectively etching the block copolymer layer to remove the multiple structures, forming holes in the block copolymer layer; and using the holes in the block copolymer layer to facilitate providing electrical contacts between a light absorption layer of the photovoltaic cell and the electrical contact layer. For instance, the holes in the copolymer layer may be used in etching a passivation layer over the electrical contact layer to form nano-sized contact openings in the passivation layer to the contact layer. Once provided, the cell's light absorption material forms contacts extending through the contact openings in the passivation layer.
