Abstract
Methods of fabricating solar cells using simplified deposition processes, and the resulting solar cells, are described. In an example, a method of fabricating a solar cell involves loading a template substrate into a deposition chamber and, without removing the template substrate from the deposition chamber, performing a deposition method. The deposition method involves forming a first silicon layer on the template substrate, the first silicon layer of a first conductivity type. The deposition method also involves forming a second silicon layer on the first silicon layer, the second silicon layer of the first conductivity type. The deposition method also involves forming a third silicon layer above the second silicon layer, the third silicon layer of a second conductivity type. The deposition method also involves forming a solid state doping layer on the third silicon layer, the solid state doping layer of the first conductivity type.
