Semiconductor with silver patterns having pattern segments

摘要

A photovoltaic cell and method of forming the cell includes providing an electroformed metallic article having a plurality of electroformed elements that form a free-standing, unitary piece. The metallic article has gridlines that are spaced apart at a pitch PM. A semiconductor substrate has a top surface with a plurality of silver, where at least one of the silver patterns comprises pattern segments spaced apart at a pitch PS. The pattern segments have a length LS defined by the equation LS=PM−k*PS/2, k being a value from 1.0 to 1.4. The metallic article is coupled to the semiconductor substrate, in which a first electroformed element in the plurality of electroformed elements is coupled to a first silver pattern in the plurality of silver patterns.
