NOVELTY - A thin-film solar cell module comprises transparent insulating substrate, thin film solar cell, bus, sealing mechanism, and wiring element. The module has several photovoltaic elements, each having layers of transparent and black electrodes and thin film semiconductor. An insulating sheet is disposed between the wiring element buried in a filler and back electrode layer of sealing mechanism.    USE - Useful as thin-film solar cells for sunlight power generation.    ADVANTAGE - The wiring elements are buried, thus enhancing reliability, and reducing the possibility of contact between the wiring elements and metal in back protection cover. The insulating sheet prevents water or water vapor to coagulate and corrode the internal component. The method eliminates caulking the opening portions of silicone resin, thus making the inventive method simple and convenient.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing the thin-film solar cell module comprising sequentially forming a thin film solar cell, wiring element (5, 5') between bus (3, 3') and connection mechanism, and sealing mechanism. A photovoltaic layer is formed by stacking on a transparent insulting substrate (1), transparent electrode layers, photovoltaic thin film semiconductor layer, and back electrode layer. The photovoltaic layer is divided into several regions. Wiring element is formed by disposing sequentially a filler, insulating sheet (7) and a filler (9) on solar cell, and under wiring element. The sealing mechanism is formed by disposing the filler sheet, a back protection cover (13) at position corresponding to an opening (14) of filler sheet (12). The filler sheet has opening for leading out the wiring element to connection mechanism.    DESCRIPTION OF DRAWING(S) - The figure shows a perspective view of a thin-film solar cell.
