Abstract

A photo voltaic cell has base and emitter areas and contacts to these areas on the back surface. Additional floating conductors are provided on the front surface. The conductors extend on the front surface, from over the emitter areas on the back surface to over the base areas on the back surface. In this way, the effect of electrode shading is reduced.
