    Abstract: According to one aspect of the disclosed subject matter, a monolithically isled solar cell is provided. The solar cell comprises a semiconductor layer having a light receiving frontside and a backside opposite the frontside and attached to an electrically insulating backplane. A trench isolation pattern partitions the semiconductor layer into electrically isolated isles on the electrically insulating backplane. A first metal layer having base and emitter electrodes is positioned on the semiconductor layer backside. A patterned second metal layer providing cell interconnection and connected to the first metal layer by via plugs is positioned on the backplane.

    Abstract: Fabrication methods and structures relating to multi-level metallization of solar cells are described. In one embodiment, a back contact solar cell comprises a substrate having a light receiving frontside surface and a backside surface for forming patterned emitter and base regions. A first electrically conductive metallization layer is patterned on the backside base and emitter regions. An electrically insulating layer is formed on the first electrically conductive metallization layer and a second electrically conductive metallization layer is formed on the electrically insulating layer. The second electrically conductive metallization layer is connected to the first electrically conductive metallization layer through conductive via plugs formed in the electrically insulating layer.

    Abstract: Various laser processing schemes are disclosed for producing various types of hetero junction and homo-junction solar cells. The methods include base and emitter contact opening, selective doping, metal ablation, annealing to improve passivation, and selective emitter doping via laser heating of aluminum. Also, laser processing schemes are disclosed that are suitable for selective amorphous silicon ablation and selective doping for hetero-junction solar cells. Laser ablation techniques are disclosed that leave the underlying silicon substantially undamaged. These laser processing techniques may be applied to semiconductor substrates, including crystalline silicon substrates, and further including crystalline silicon substrates which are manufactured either through wire saw wafering methods or via epitaxial deposition processes, or other cleavage techniques such as ion implantation and heating, that are either planar or textured/three-dimensional. These techniques are highly suited to thin crystalline semiconductor, including thin crystalline silicon films.
