Title: Fabrication of back-contacted silicon solar cells using thermomigration to create conductive vias

Abstract

Methods of manufacturing back-contacted silicon solar cells fabricated using a gradient-driven solute transport process, such as thermomigration or electromigration, to create n-type conductive vias connecting the n-type emitter layer on the front side to n-type ohmic contacts located on the back side.
