Patent number: 6262359Abstract: A process for fabricating a solar cell is described. The process includes: (1) providing a base layer, (2) fabricating an emitter layer of p-type conductivity on a same side as the non-illuminated surface of the base layer to provide a strongly doped p-type emitter layer and a p-n junction between the n-type base layer and the p-type emitter layer. The base layer of the present invention has n-type conductivity and is defined by an illuminated surface and a non-illuminated surface. The illuminated surface has light energy impinging thereon when the solar cell is exposed to the light energy and the non-illuminated surface is opposite the illuminated surface.Type: GrantFiled: October 7, 1999Date of Patent: July 17, 2001Assignee: Ebara Solar, Inc.Inventors: Daniel L.
