Appl. No.:

13/791067

Inventors:

Jen SHU - Saratoga CA, US
James M. GEE - Albuquerque NM, US

International Classification:

H01L 31/18

US Classification:

438 98, 29 2501, 252512, 252513, 252515, 25251934

Abstract:

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.

Abstract:

Apparatuses and assembly methods are provided for a monolithic solar cell panel assembly. The assembly comprises an array of solar cells having front electrical contacts and back electrical contacts, wherein a first set of the solar cells in the array are aligned to be electrically connected in series through a back circuit sheet having an array of back metal contacts connected to corresponding back electrical contacts on the first set of solar cells, and through a front circuit sheet having an array of front metal contacts connected to corresponding front electrical contacts on the first set of solar cells. Electrical connections may be made in a lamination step, in which an encapsulant polymer flows into gaps and an interconnect material connects the circuits to form the monolithic solar cell panel assembly.
