Abstract
According to one aspect of the disclosed subject matter, a monolithically isled solar cell is provided. The solar cell comprises a semiconductor layer having a light receiving frontside and a backside opposite the frontside and attached to an electrically insulating backplane. A trench isolation pattern partitions the semiconductor layer into electrically isolated isles on the electrically insulating backplane. A first metal layer having base and emitter electrodes is positioned on the semiconductor layer backside. A patterned second metal layer providing cell interconnection and connected to the first metal layer by via plugs is positioned on the backplane.
