AbstractInexpensive solar cell contacts can be made using silicone or epoxy materials with carbon nanostructure additives to improve electrical conductivity at high temperature. This overcomes the problems associated with metal-additive silicones and epoxies, which tend to lose their electrical conductivity enhancements as the temperature increases, thereby diminishing; their usefulness as a solar cell electrical conduct. Because highly conductive carbon fib r can be fabricated with an extremely high aspect ratio (L/D > 5000), bonding material incorporating this fiber will have an internal conductive network within it, assuring that electrical contact will be maintained as the material expands thermally.
