Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for the manufacture of a back contact back junction thin solar cell from a crystalline semiconductor layer, the method providing continuous structural support to said crystalline semiconductor layer, the method comprising: forming a porous semiconductor layer on a template, wherein said template provides structural support and acts as a high temperature temporary carrier for back contact back junction solar cell backside processing steps, said backs…
