NOVELTY - Fabricating photovoltaic cell modules involves bringing at least one sheet of organopolysiloxane based hot melt material (102a, 104a) into contact with a photovoltaic cell or an array of photovoltaic cells (103a) and/or a light transparent superstrate (101a) at room temperature; heating the sheets of hot melt material to adhere to the photovoltaic cells and/or to the superstrate; and cooling the product.    USE - For fabricating photovoltaic cell modules such as solar cells (claimed), semiconductor device useful for converting light into electricity.    ADVANTAGE - The hot melt materials are designed to provide a sufficient green strength for applications requiring strong initial bonds between the hot melt material. The sheets are non tacky at room temperature and/or prior to heating, thereby avoiding potential handling problems involved in the application of tacky sheets. The method provides increased throughput and optical efficiency when compared to prior art encapsulation methods due to the simplicity of the process utilized by using silicone hot melt sheet which is tack free and processes at comparably faster speeds, equal or lower laminating temperatures to existing organic ethyl vinyl acetate (EVA) encapsulant. The resulting product provides improved cell efficiency by utilizing UV sensitive cells in combination with light transparent superstrate and light transparent silicone. The cured organopolysiloxane hot melt material resulting from the sheets exhibits long term ultraviolet and visual light transmission thereby allowing the maximum amount of light to reach solar cells. The cell reduces laminator cycle time by more than 20% or the laminator could be completely eliminated.    DETAILED DESCRIPTION - Fabricating photovoltaic cell modules involves bringing at least one sheet of organopolysiloxane based hot melt material (102a, 104a) into contact with a photovoltaic cell or an array of photovoltaic cells (103a) and/or a light transparent superstrate (101a) at room temperature; heating the sheets of hot melt material to adhere to the photovoltaic cells and/or to the superstrate; and cooling the product. The method involves applying a thin film photovoltaic cell on to a transparent superstrate, and applying sheets of organopolysiloxane based hot melt material on the thin film. The hot melt material is a reactive hot melt material. The hot melt sheets additionally contain at least one additive. INDEPENDENT CLAIMS are included for the following:    (1) a photovoltaic cell module comprising a photovoltaic cell or an array of photovoltaic cells encapsulated in an organopolysiloxane based hot melt material that is adhered to a light transparent superstrate and optionally to a supporting substrate; and    (2) use of sheets of organopolysiloxane based hot melt material in the encapsulation of solar cells.
