ABSTRACT:
A process of encapsulating solar cells in which a semiconductor wafer first is processed into an uncut cell. An interconnect strip is secured to the front contact of the cell. A coverglass plate, provided with a suitable coating, is next bonded to the front surface of the cell. Finally, the bonded assembly of cell and coverglass plate is cut to final size as a unit. The interconnect strip preferably is folded onto the back surface of the cell either during or prior to the cutting operation.
