How to design optimal metallization patterns for solar cells

Abstract

Solar cells have a metallization pattern to collect the current. Generally, simple, metallization patterns, such as the H-grid metallization pattern, a cross-hatched pattern or a full metallization, are used. With the widely used technique of screen printing, however, virtually any metallization pattern of any topology can be realized, but the problem is how to design the optimum topology. The paper presents a design method for optimal metallization patterns.
