PROTECTION LAYER FOR FOIL-BASED METALLIZATION OF SOLAR CELLS

摘要

Approaches for foil-based metallization of solar cells are described. For example, a method of fabricating a solar cell involves placing a metal foil over a metalized surface of a wafer of the solar cell. The method further involves placing a protection layer over the metal foil. The method further involves locating the metal foil with the metalized surface of the wafer. The protection layer preserves an optically consistent surface of the metal foil during the locating. The method also involves, subsequent to the locating, electrically contacting the metal foil to the metalized surface of the wafer.
