SELF ALIGNED CONTACTS FOR BACK CONTACT SOLAR CELLS
摘要
According to one aspect of the disclosed subject matter, self aligned contacts for a back contact back junction solar cell are 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 first metal layer having base and emitter electrodes self aligned to base and emitter regions 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.
