A laser processing system can be utilized to produce high-performance interdigitated back contact (IBC) solar cells. The laser processing system can be utilized to ablate, transfer material, and/or laser-dope or laser fire contacts. Laser ablation can be utilized to remove and pattern openings in a passivated or emitter layer. Laser transferring may then be utilized to transfer dopant and/or contact materials to the patterned openings, thereby forming an interdigitated finger pattern. The laser processing system may also be utilized to plate a conductive material on top of the transferred dopant or contact materials.

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.

A deposition process for coating a substrate with films of varying thickness on a substrate can be achieve. The thickness of the film deposition can be controlled by the separation between the substrate and a curtain. Different separation distances between the substrate and curtain in the same chemical bath will result in different film thicknesses depositing on the substrate.

A film deposited on substrate may originally has a high surface recombination velocity (SRV). In order to suppress the SRV and increase the minority carrier lifetime, the substrate may be treated annealing at a high temperature in gas ambient containing O
