Abstract
A solar cell structure is provided for reducing shadow losses without increasing series resistance in the solar cell device. The solar cell device may form an electrical contact to a solar cell emitter layer from the backside of the solar cell device. With this structure, the emitter contact shadow losses may be reduced significantly while simultaneously decreasing device series resistance.
