Abstract: Embodiments of the present invention are directed to processes for making solar cells by simultaneously co-firing metal layers disposed both on a first and a second surface of a bifacial solar cell substrate. Embodiments of the invention may also provide a method forming a solar cell structure that utilize a reduced amount of a silver paste on a front surface of the solar cell substrate and a patterned aluminum metallization paste on a rear surface of the solar cell substrate to form a rear surface contact structure. Embodiments can be used to form passivated emitter and rear cells (PERC), passivated emitter rear locally diffused solar cells (PERL), passivated emitter, rear totally-diffused (PERT), “iPERC,” Crystalline Reduced-cost Aluminum Fire-Through (CRAFT), pCRAFT, nCRAFT or other high efficiency cell concepts.

Abstract: Embodiments of the present disclosure provide a method and an apparatus for processing a substrate. The apparatus has a ring assembly. The ring assembly has an edge ring and a shadow ring. The edge ring has a ring shaped body. The edge ring body has a top surface and a bottom surface. Pin holes extend through the edge ring body from the top surface to the bottom surface. The shadow ring has a ring shaped body. The shadow ring body has an upper surface and a lower surface. Sockets are formed on the lower surface, wherein the sockets in the shadow ring body align with the pin holes in the edge ring body.
