STRUCTURES AND METHODS FOR FORMING ELECTRODES OF SOLAR CELLS

Abstract:

Solar cells are attached together to form a plating assembly. The plating assembly is attached to a belt, which transports the plating assembly through a plating chamber where metal is electroplated on the solar cells. The electroplated metal is patterned to form metal contact fingers. After the metal is electroplated, the plating assembly is singulated to separate the two solar cells.
