National Renewable Energy Laboratory - Visit the NREL Technology Transfer Website
A photovoltaic cell module having an impact resistance of greater than 1,200 grams includes a first layer, a silicone elastomer disposed on the first layer and a crystalline photovoltaic cell disposed on the silicone elastomer. The module also includes a second elastomer disposed opposite the silicone elastomer and on the crystalline photovoltaic cell. The module is formed using a method that includes the step of contacting a hydrosilylation-curable silicone composition and/or a cured silicone gel thereof with an organosilicon compound including at least two silicon-bonded hydrogen atoms per molecule. The method also includes the step of disposing the second elastomer opposite the silicone elastomer and on the crystalline photovoltaic cell. The hydrosilylation-curable silicone composition includes an organopolysiloxane having an average of at least two silicon-bonded alkenyl groups per molecule, an organohydrogensiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule, and a hydrosilylation catalyst.
