AN ALUMINUM ALLOY BACK JUNCTION SOLAR CELL AND A PROCESS FOR FABRICATION THEREOF

摘要

A process for fabricating a solar cell is described. The process includes: providing a base layer (118), and fabricating an emitter layer (120) of p-ty pe conductivity on a same side as the non-illuminated surface (128) of the base layer to provide a strongly doped p-type emitter layer and a p-n junction (124) between the n-type base layer (118) and the p-type emitter layer (120) . The base layer of the present invention has n-type conductivity and is defin ed by an illuminated surface (126) and a non-illuminated surface (128) which is opposite to the illuminated surface.
