Title: ALIGNMENT FOR METALLIZATION
Abstract:
Forming a metal layer on a solar cell. Forming a metal layer can include placing a patterned metal foil on the solar cell, where the patterned metal foil includes a positive busbar, a negative busbar, a positive contact finger extending from the positive busbar, a negative contact finger extending from the negative busbar, a metal strip, and one or more tabs. The positive and negative busbars and the positive and negative contact fingers can be connected to one another by the metal strip and tabs. Forming the metal layer can further include coupling the patterned metal foil to the solar cell and removing the metal strip and tabs. Removing the metal strip and tabs can separate the positive and negative busbars and contact fingers.
