Abstract
Back contact back junction solar cell and methods for manufacturing are provided. The back contact back junction solar cell comprises a substrate having a light capturing frontside surface with a passivation layer, a doped base region, and a doped backside emitter region with a polarity opposite the doped base region. A backside passivation layer and patterned reflective layer on the emitter form a light trapping backside mirror. An interdigitated metallization pattern is positioned on the backside of the solar cell and a permanent reinforcement provides support to the cell.
