The gasket so formed is deformable under a predetermined compressive force between the first and second interface surfaces into a stressed orientation characterized in that the body is deflected intermediate the base and apex surfaces.

A method of making thermodynamically stable, diffusion-impeded barrier layers within, for example, a photovoltaic cell with a metal-containing electrical contact using exposure to fluorine.
