Abstract: A back contact back junction solar cell using semiconductor wafers and methods for manufacturing are provided. The back contact back junction solar cell comprises a semiconductor wafer having a doped base region, a light capturing front side surface, and a doped backside emitter region. A front side and backside dielectric layer and passivation layer provide enhance light trapping and internal reflection. Backside base and emitter contacts are connected to metal interconnects forming a metallization pattern of interdigitated fingers and busbars on the backside of the solar cell.
