Design of an electrode pattern Generally, a crystalline silicon solar cell has metal electrodes on the front and rear side of the surface. The electrodes consist of Ag fingers and busbars on the front side, Al electrodes and Ag pads (or busbars) on the rear side; each electrode has its own function.
In this study, we designed the busbar-free electrode pattern of the crystalline silicon solar cells suitable for the shingled PV modules. The characteristics of the divided cell strips with the busbar-free patterns was similar to those of the conventional patterns.
