Solar-cell module and process for its production, building material and method for its laying, and electricity generation system

摘要

A solar-cell module (1) is provided which comprises a photovoltaic device (2) sealed on a reinforcing sheet (5) with a filler material (3), wherein the reinforcing sheet has unevenness formed by plastic deformation, on its surface at least on the side of the photovoltaic device and at least partly on the surface, and a space defined by the unevenness and the photovoltaic device is filled with the filler material. The solar-cell module is produced by a process where a thermoplastic-resin sheet member and a photovoltaic device on a reinforcing sheet having unevenness on its surface are heated while removing air from the spaces between the thermoplastic resin sheet member, the photovoltaic device, and the reinforcing sheet. A solar-cell module can thereby be provided which has no trapped air portions that may be formed between the filler material and the reinforcing sheet when the photovoltaic device is sealed with the filler material and fixed onto the reinforcing sheet to produce the solar-cell module. The solar-cell module can be used as a building material and/or in an electricity generation system. IMAGE
