The production of low-cost, resource-saving solar modules is one of the central technical challenges of the next decade. KIT and PROTAVIC INTERNATIONAL want to make a joint contribution. They are developing a "super adhesive" that will be used, among other things, for the assembly of microelectronic devices and for the production of photovoltaic modules. The object of the cooperation is the development of an electrically conductive structural adhesive with high conductivity and low silver content. Polymer resins and silver particles produced by PROTAVIC INTERNATIONAL serve as the basis. The high conductivity is achieved by applying the capillary suspension concept developed by KIT. This is based on the fact that when the solid and the first liquid are mixed, a stable particle network is created by the small addition of a second liquid that is not miscible with the main phase. This network is held together by capillary forces and allows high conductivity to be achieved even at low particle concentrations.
