Abstract
Structures and methods for a solar cell having an integrated bypass switch are provided. According to one embodiment, an integrated solar cell and bypass switch comprising a semiconductor layer having background doping, a frontside, and a backside is provided. A patterned first level metal is positioned on the layer backside and an electrically insulating backplane is positioned on the first level metal. A trench isolation pattern partitions the semiconductor layer into a solar cell region and at least one monolithically integrated bypass switch region. A patterned second level metal is positioned on the electrically insulating backplane and which connects to the first level metal through the backplane to complete the electrical metallization of the monolithically integrated solar cell and bypass switch structure.
