PURPOSE:To obtain a device having excellent weatherproof by applying a surface treatment to a resin coating section for an external lead and sealing a takeoff section with an Si rubber having a predetermined viscosity. CONSTITUTION:The end sections of solar cell elements 2 are superposed each other and connected in series, and sealed with a transparent Si rubber having 2,000cp or less. The element 2 is connected to a steel plate 10 fitted to a partition wall 1a for a vessel through an internal lead 4, and an external lead 5 is soldered to the steel plate 10. Sections except a bare section 5a for the lead 5 are coated with a polyvinyl chloride resin 5b. An silane coupling agent is applied to a takeoff section for the external lead, and a through-hole section 1b is closed primarily with an Si rubber 11 having a viscosity of 40,000cp or more, and closed completely under a liquid-tight state with an Si rubber 12 having a viscosity of 10,000cp or less. According to the constitution, moisture does not adhere to the bare wire section 5b for the lead and the element 2, thus acquiring a solar cell module having excellent weatherproof. |
