A surface of one substrate is bonded to a surface of another substrate employing a low temperature vulcanizing carborane siloxane adhesive composition. The bonding method comprises: (a) forming a solution comprising (1) a polycarborane siloxane polymer having vinyl groups attached to the backbone thereof, the concentration of vinyl groups per carborane group ranging from about 3 to 30%, (2) a difunctional silane curing agent, (3) a catalyst comprising a transition metal complex, and (4) a chosen solvent; (b) applying the solution to at least one of the surfaces; (c) allowing the solvent to evaporate, forming a thin film of the adhesive on the surface; (d) bringing the surfaces of the substrates into contact; and (e) bonding the surfaces of the substrates together by application of heat and, optionally, pressure. Optionally, the coated part(s) may be stored at a low temperature for a long period of time prior to the bonding process. This invention is particularly useful for bonding a solar cell cover to a solar cell or for bonding solar cells to an underlying substrate.
