NOVELTY - Making a solar cell module, comprises: (i) coating a curable silicone gel composition onto one surface of each panel except its peripheral region and curing; (ii) providing a seal member on the region of the one surface of one panel where the cured gel coating is not formed, and placing the solar cell component on the cured gel coating; (iii) placing the other panel on the one panel while the cured silicone gel coating on the other panel facing the solar cell component; and (iv) pressing the two panels together while heating in vacuum for encapsulating the solar cell component.    USE - The method is useful for manufacturing a solar cell module (claimed) for use in outdoor applications.    ADVANTAGE - The method is capable of enabling to use an existing solar module manufacturing apparatus, avoiding entrainment of air bubbles, and causing no damages to the solar cell component, thus the resulting solar cell module is fully durable in that any ingress of moisture from side edges of the module is prohibited. The solar cell module has enhanced conversion efficiency, long-term reliability, improved transparency, good weather resistance and excellent shock resistance. The solar cell module can be easily manufactured in an industrial scale.    DETAILED DESCRIPTION - Manufacturing a solar cell module by encapsulating a semiconductor substrate-based solar cell component between two panels, comprises: (i) coating a curable silicone gel composition onto one surface of each panel except its peripheral region and curing the composition to form a cured silicone gel coating having a penetration of 30-200 as measured according to JIS K2220; (ii) providing a seal member on the peripheral region of one surface of one panel where the cured silicone gel coating is not formed and the seal member is made of a butyl rubber-based thermoplastic sealing material and is thicker than the cured silicone gel coating, and placing the solar cell component on the cured silicone gel coating; (iii) placing the other panel on the one panel while the cured silicone gel coating on the other panel facing the solar cell component so that the seal member abuts against the peripheral region of the one surface of the other panel where the cured silicone gel coating is not formed, and the solar cell component is sandwiched between the cured silicone gel coatings on the panels; and (iv) pressing the two panels together while heating in vacuum for encapsulating the solar cell component.
