A process for producing a substrate having a coating resin layer includes the steps of carrying in a substrate on a fastening table and fastening the substrate to the table and, while moving a spout for spouting a resin layer precursor or the fastening table in a horizontal direction, spouting the resin layer precursor to apply the resin layer precursor onto the substrate to form a resin layer precursor layer on the substrate. Additional steps include carrying out the substrate having the resin layer precursor layer from the fastening table, and drying and curing the resin layer precursor layer on the substrate to form a coating resin layer on the substrate.

A portion of one conductor is bent to form a facing portion where two regions face each other, the facing portion and another conductor are inserted into a ring-shaped caulking member, and crimping is effected. This obviates the need for cutting a conductor in the work of coupling the conductor with a plurality of branch lines and the need for preliminarily threading the conductor through ring-shaped caulking members. Thus, it is feasible to improve reliability of electrical connection and to add a new branch line readily.

To optimally arrange roofing material integrated solar battery modules having a rectangular form and same size on a roof setting surface, an arrangement range in which the solar battery modules can be arranged on the roof setting surface is determined. An arranging direction of the solar battery modules is determined. The number of solar battery modules which can be arranged almost horizontally in a line in the determined arranging direction and within the arrangement range is calculated. Solar battery modules of a line in a number not more than the calculated number are combined to form a solar battery module group. The solar battery module groups are arranged to set a center of the solar battery module group within the determined arrangement range and near a line almost vertically dividing the surface into two parts. The above operations are repeated a number of times corresponding to the number of lines of solar battery module groups which can be vertically arranged in the determined arranging direction and within the arrangement range.

A solar cell module comprises a front surface member disposed on a front surface side of a photovoltaic element having at least a semiconductor photoactive layer on a flexible substrate, a back surface member disposed on a back surface side of the photovoltaic element, and a sealing material interposed therebetween. The flexible substrate of the photovoltaic element has a plurality of substantially parallel surface grooves on a surface thereof at the semiconductor photoactive layer side of the flexible substrate. At least one portion of the solar cell module is processed to deform in such a direction that strain generated in a substantially parallel direction to the surface grooves is applied to the photovoltaic element. In this way, a solar cell module can be subjected to deformation-processing that prevents, to the extent possible, cracks in the semiconductor photoactive layer of the photovoltaic elements; in other words, deformation-processing can be achieved without influencing electrical characteristics. A method of producing such a solar cell module is also disclosed.

A solar-cell module is provided which comprises a photovoltaic device sealed on a reinforcing sheet with a filler material, 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 comprising the steps of superposing at least a thermoplastic-resin sheet member and a photovoltaic device on a reinforcing sheet having unevenness on its surface, and heating the thermoplastic-resin sheet member, the photovoltaic device and the reinforcing sheet while removing air from a space between the reinforcing sheet and the thermoplastic-resin sheet member and a space between the thermoplastic resin sheet member and the photovoltaic device, to bring them into close contact to fix to each other.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 present invention provides a method for manufacturing a solar cell module having photovoltaic elements in each of which a metal oxide layer made of a metal oxide forms an outermost surface part thereof at a light incident side, and a sealing resin layer formed on the metal oxide layer. The method includes the steps of providing water on a surface of the metal oxide layer, the water being chemically adsorbed thereto; irradiating the metal oxide layer with electromagnetic waves for a predetermined time so that the contact angle of the water on the surface of the metal oxide layer is 60° or less, the electromagnetic waves having energy larger than the band gap of the metal oxide; and subsequently forming the sealing resin layer on the metal oxide layer.

In a power generation system of this invention, the outputs from power generation layers electrically connected in series are input to corresponding power conversion devices, and boosted outputs are connected in parallel and fed to a load. Alternatively, the output from one of power generation layers electrically connected in series is input to a first power conversion device, and the serial output and the boosted output from the first power conversion device are connected in parallel, input to a second power conversion device, boosted, and fed to the load. Since the two power generation layers can be individually output-controlled, each power generation layer can be optimized basically without considering current balance. Since the optical spectrum utilization efficiency increases, the power generation efficiency increases. In addition, since the power can be fed not to separate loads but to one load, the convenience largely increases.
