Abstract

The present invention is a PV cell design which introduces one or multiple additional electrical contacts on a PV cell. For PV modules that are constructed with shingled PV cells this invention makes it convenient to: 1) connect metal ribbons to shingled PV strings only from the rear side of the PV cells; 2) incorporate by-pass diodes; and 3) establish inter-string connection. The present invention also improves the aesthetics, reliability, and durability of PV modules that are constructed with shingled PV cells.
