  • Method of fabricating a photovoltaic module of a substantially transparent construction
    Patent number: 4184903
    Abstract: A method characterized by the steps of positioning a plurality of uniformly dimensioned photovoltaic cells in registered relation with a plurality of openings formed in a planar tool for affording access to the P contact surface of each of the cells, connecting the N contact surface of alternate cells to the P contact surface of the cells interposed therebetween, removing therefrom residue of solder flux, applying to the N contact surfaces of the cells a transparent adhesive, placing a common transparent cover plate in engaged relation with the adhesive, placing a film over the circular openings for hermetically sealing the openings, and establishing a vacuum between the film and the cover plate for thus simultaneously forcing the cells into vacuum bonded relation with the cover plate.
