In a sheet-shaped solar module mounting structure, rail members include locking members to which the end portions of sheet-shaped solar batteries are locked, so that, in mounting the sheet-shaped solar batteries to a roof bed, it is unnecessary to nail the solar batteries to the roof bed with screws or the like.

Sheet-shaped solar module mounting structure

The roof of a solar house includes a plurality of crosspieces arranged parallel to each other, and a solar battery roofing for the solar house is fixed to the crosspieces. The solar battery is formed of a plurality of solar cells connected in series to form a solar cell row arranged parallel to the crosspieces. In case a plurality of solar cell rows is used, the solar cell rows are arranged parallel to each other, and the first and last solar cells in the rows are electrically connected to each other.

Solar battery roofing for a solar house

Solar cell made using a heterojunction formed from a crystalline silicon layer of a first conductivity type and a hydrogenated amorphous silicon film of a second conductivity type different from the first conductivity type. The hydrogenated amorphous silicon film includes oxygen.

Solar cell and a method for the manufacture thereof

To reduce power loss in a transparent electrode with a high sheet resistance in a thin-film solar cell that uses an amorphous semiconductor layer, without having to use a complex patterning process. A large number of holes are formed through an insulating substrate, while a third electrode layer with a low sheet resistance is disposed on the rear side of the substrate and a transparent second electrode layer disposed on the light incidence side. The second and third electrode layers are connected to each other via said holes. To build a series-connection structure, an extended portion of the third electrode layer on one cell and extended portions of the first electrode layers on adjoining cells are connected to each other via similar holes formed on the substrate.

Thin-film solar cell and method for the manufacture thereof

In a laser CVD device, immediately before being emitted from a nozzle, raw gas in a reaction chamber reacts opto-chemically with a focused laser beam so that it is decomposed to form a radical flow. The radical flow flows against a substrate set in the reaction chamber so that active materials produced by the optochemical decomposition accumulate on the substrate to form a thin film thereon.
