Abstract
Methods of fabricating solar cells having a plurality of sub-cells coupled by cell level interconnection, and the resulting solar cells, are described herein. In an example, a solar cell includes a plurality of sub-cells. Each of the plurality of sub-cells includes a singulated and physically separated semiconductor substrate portion. Each of the plurality of sub-cells includes an on-sub-cell metallization structure interconnecting emitter regions of the sub-cell. An inter-sub-cell metallization structure couples adjacent ones of the plurality of sub-cells. The inter-sub-cell metallization structure is different in composition from the on-sub-cell metallization structure.
