摘要： 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.

摘要： Lateral multi junction photovoltaic cells, devices, and methods of fabrication are provided. The photovoltaic cells include a plurality of photovoltaic subcells mechanically stacked together in a stack. Each photovoltaic subcell includes a subcell substrate, and a light absorption structure associated with the substrate. Each light absorption structure is optimized for a respective defined spectral range of incoming radiation, with the light absorption structures of multiple subcells of the plurality of photovoltaic subcells being optimized for different spectral ranges, and being offset in the stack relative to an optical axis to avoid overlap. The photovoltaic cell further includes a spectrally-dispersive optical element, with the photovoltaic subcells in the stack being respectively located and aligned relative to the optical element based, at least in part, on the respective spectral ranges of the subcells' light absorption structures.
