Exterior Edge Seal for a Module

Abstract

An external edge seal is used at the exterior edges of different modules to decrease the permeation of moisture and reactive gas to lengthen the life span of the modules. The sealed module can be a photovoltaic module, an insulating glass unit, a screen, a dynamic glazing product, a switchable window, an electrochromic window, a thin-film transistor, or other modules using items between substrates. The edge seal includes a desiccated adhesive carried by a barrier film to form a tape. The vapor barrier can be placed along the edge of a sealed module or around the edge and against portions of the outer substrate surfaces of the sealed module to provide a desiccated seal that provides or lengthens the desiccated path that moisture vapor must follow before permeating the inner space of the sealed module.
