A fabrication line includes a texturizing module configured to texture a substrate, an emitter module configured to form an emitter region, a passivation layer module configured to form a passivation layer, a barrier contact module configured to form a barrier contact region, a firing module configured to anneal the barrier contact region, a top metal contact module configured to form a top metal contact region, and a soldering module configured to solder the barrier contact region to the top metal contact region. The modules are integrated by one or more automated substrate handlers into a single fabrication line. A method for fabricating a solar cell includes sequentially, in an automated fabrication line: doping a dopant in a substrate; disposing a passivation layer; disposing and annealing a barrier metal paste to form a barrier contact; and disposing and annealing a metal contact paste to form a top metal contact region.
