  • Photovoltaic cell with junction-free essentially-linear connections to its contacts
    Patent number: 4153907
    Abstract: Admixed glass frits and conductor-forming materials are applied directly to selected portions of the smooth-surface, doped areas of photovoltaic cells, and then are fired to form electrical contacts for those smooth-surface, doped areas. Those conductor-forming materials form electrical contacts that have essentially-linear, low resistance, electrical connections with those smooth-surface, doped areas and also provide exposed surfaces to which leads can be bonded; and those glass frits fuse to the smooth surfaces of the doped areas of those photovoltaic cells to provide sturdy mechanical bonds between those electrical contacts and those smooth-surface, doped areas.
