    摘要: The present disclosure provides a method of forming a back side surface field of a solar cell without utilizing screen printing. The method includes first forming a p-type dopant layer directly on the back side surface of the semiconductor substrate that includes a p/n junction utilizing an electrodeposition method. The p/n junction is defined as the interface that is formed between an n-type semiconductor portion of the substrate and an underlying p-type semiconductor portion of the substrate. The plated structure is then annealed to from a P++ back side surface field layer directly on the back side surface of the semiconductor substrate. Optionally, a metallic film can be electrodeposited on an exposed surface of the P++ back side surface layer.

    摘要: Alternative additives that can be used in place of isopropyl alcohol in aqueous alkaline etchant solutions for texturing a surface of a single-crystalline silicon substrate are provided. The alternative additives do not have volatile constituents, yet can be used in an aqueous alkaline etchant solution to provide a pyramidal shaped texture surface to the single-crystalline silicon substrate that is exposed to such an etchant solution. Also provided is a method of forming a textured silicon surface. The method includes immersing a single-crystalline silicon substrate into an etchant solution to form a pyramid shaped textured surface on the single-crystalline silicon substrate. The etchant solution includes an alkaline component, silicon (etched into the solution as a bath conditioner) and glycerol or ethylene glycol as an additive. The textured surface of the single-crystalline silicon substrate has (111) faces that are now exposed.
