ABSTRACT:
A pyramidal three-dimensional thin-film solar cell, comprising a pyramidal three-dimensional thin-film solar cell substrate comprising a plurality of pyramid-shaped unit cells with emitter junction regions and doped base regions, emitter metallization regions and base metallization regions. Optionally, the pyramidal three-dimensional thin-film solar cell may be mounted on a rear mirror for improved light trapping and conversion efficiency.
