  • Publication number: 20160056307
    Abstract: The inventors of the present disclosure recognized that elimination or reduction of the silver paste and/or silver busbars on the front and/or rear surfaces of solar cells and solar modules would advantageously lower the total cost of the solar cell and/or solar module. The inventors of the present disclosure recognized that the silver paste on the front and rear surface of solar cells or solar modules can be eliminated or the amount of silver paste reduced by replacing the silver busbars with a solderable tape including a conductive metal foil and a nonconductive adhesive.

  • Patent number: 6906534
    Abstract: A breathable moisture barrier suitable for use in enclosing flexible electrodes, foam substrate and other electrical components within a substantially liquid impervious environment without significantly impairing the ability of electrical sensors to accurately measure temperature and humidity variations within the surrounding environment such as the seating compartment of an automobile. It is further disclosed that a breathable polymeric material having a sufficiently high moisture vapor transmission rate (MVTR) will permit water vapor to be transported across the barrier and quickly reach equilibrium within the enclosed seat sensor mat assembly and to allow the humidity compensation of the occupant sensing system to function correctly.
