Abstract
Various embodiments provide a solar cell. The solar cell includes a substrate having a front side and a rear side. At least the front side receives light. The solar cell further includes a multiplicity of rear side solder pad regions at least partially arranged over the rear side, and a plurality of partial solder pads formed in each rear side solder pad region of the multiplicity of rear side solder pad regions. Each partial solder pad includes a first metal. The partial solder pads in a respective rear side solder pad region are separated from each other. The solar cell further includes a rear side metallization formed at the rear side of the substrate partly overlapping the partial solder pads, the rear side metallization including a second metal different from the first metal.
