摘要: Systems and methods for producing nanoscale textured low reflectivity surfaces may be utilized to fabricate solar cells. A substrate may be patterned with a resist prior to an etching process that produces a nanoscale texture on the surface of the substrate. Additionally, the substrate may be subjected to a dopant diffusion process. Prior to dopant diffusion, the substrate may be optionally subjected to liquid phase deposition to deposit a material that allows for patterned doping. The order of the nanoscale texture etching and dopant diffusion may be modified as desired to produce post-nano emitters or pre-nano emitters.

摘要: A method for an improved doping process allows for improved control of doping concentrations on a substrate. The method may comprise printing a polymeric material on a substrate in a desired pattern; and depositing a barrier layer on the substrate with a liquid phase deposition process, wherein a pattern of the barrier layer is defined by the polymeric material. The method further comprises removing the polymeric material, and doping the substrate. The barrier layer substantially prevents or reduces doping of the substrate to allow patterned doping regions to be formed on the substrate. The method can be repeated to allow additional doping regions to be formed on the substrate.
