Abstract
An interdigitated back contact solar cell is provided. The solar cell comprises a solar cell substrate having a light receiving frontside and a backside comprising base and emitter regions. A first level metal (M) layer is positioned on the substrate backside contacting the base and emitter regions. A second level metal (M) layer is connected to the first level metal (M) layer and comprises a base busbar and an emitter busbar. The first level metal comprises substantially orthogonal interdigitated metallization and substantially parallel interdigitated metallization positioned under and corresponding to the base and emitter busbars on the second level metal (M). The substantially parallel interdigitated metallization of Mcollects carriers of opposite polarity of the corresponding busbar.
