摘要:
Back contact back junction three dimensional solar cell and methods for manufacturing are provided. The back contact back contact back junction three dimensional solar cell comprises a three-dimensional substrate. The substrate comprises 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 is positioned on the doped backside emitter region. Backside emitter contacts and backside base contacts connected to metal interconnects and selectively formed on three-dimensional features of the backside of three-dimensional solar cell.
