Abstract: A composite material includes at least two components, wherein at least one component is present in the form of nanoparticles, which consist of at least three metals and at least one non-metal and the diameter of which is less than one micrometre, preferably less than 200 nm. The novel composite material is particularly well suited for the production of photoactive layers.

Abstract: The invention relates to a method for producing a photovoltaic thin film module (1) which is provided with a thin film solar cell system (2) that is mounted on carrier materials (3) and is covered with a compound (4) on at least one side of the surface, whereby said compound consists of an encapsulating material and is provided with a sealing layer (5) on the side of the surface thereof, said side being arranged on the thin film solar cell system (2). According to a covering method, the encapsulating material (4) and the thin film solar cell system (2), together with the carrier (3), are guided along one another and are pressed under pressure and at an increased temperature in such a way that a weather-proof, photovoltaic thin film module in the form of a compound (1) is designed. According to a method that can be carried out easily, a photovoltaic thin film module that is resistant to UV light, water vapour and other effects of the weather is provided.

Abstract: A description is given of a photovoltaic module (1) in the form of a laminate, which as the core layer exhibits a solar cell system (2) and encapsulation materials (3, 3′) applied on both sides of the latter. According to the invention, at least one encapsulation material layer (3′) consists of a sealing layer (4′) and a barrier layer (6), which consists of a plastic film or a plastic film composite, and on which an inorganic oxide layer (7) separated out to the vapor phase is present.
