Abstract
In order to reduce or prevent absorption of water in the adhesive of a panel comprising at least one photovoltaic cell located between a transparent sheet and a second sheet bonded together using an adhesive material, the invention provides that another material is applied at least in part between the sheets to form a moisture barrier which surrounds the cell(s) and the adhesive. The preferred adhesive material is polyvinyl butyral, and the preferred barrier forming material is selected from neoprene based adhesives, polysulphide adhesives and polyvinylidene chloride. When the latter is used a second barrier forming material such as polysulphide adhesive is preferably interposed between the adhesive and the polyvinylidene chloride.
