Problems solved by technology

[0008] However, the above-mentioned moisture-proof layer has poor adhesion to the resin plate, and when a solar cell module is formed by providing a filler layer in contact with the moisture-proof layer, there is a problem that the moisture-proof layer is peeled off from the resin plate.
If a gap is created between the resin sheet and the filler layer due to this peeling, water ingress, etc. will occur, resulting in a decrease in the durability of the solar cell module

Embodiment 1

[0147] For a 50 μm thick ETFE membrane (trade name: Afrax, manufactured by Asahi Glass Co., Ltd.), under a nitrogen atmosphere with a purity of 99.99% by volume, at a frequency of 40 Hz, a voltage rising time of 1.5 microseconds, a falling time of 1.5 microseconds, and a pulse duration of 20 microseconds Seconds, 30°C atmospheric pressure, processing density 354W·min / m 2 glow discharge surface treatment. Table 1 shows the measurement results of the surface composition after the surface treatment.

[0148] Next, in the acrylic resin A1 (trade name: Hals Hibride UV-G13, manufactured by Nippon Shokubai Co., Ltd.), UV absorbing groups and UV stabilizing groups (Hindered Amine Light Stabilizing Groups (HALS)) were chemically incorporated into the resin skeleton. Add 2.8 parts by mass of a curing agent (trade name: Desmojul N3200, manufactured by Sumika Bayi Polyurethane Co., Ltd. (Sumibayel Uletan)) to 100 parts by mass, dilute with toluene, and prepare a resin concentration of 10...

Embodiment 2

[0151] For a 50 μm thick ETFE film (trade name: Afrex, manufactured by Asahi Glass Co., Ltd.), in a mixed gas atmosphere composed of argon / ethylene gas / carbon dioxide gas = 100 / 7 / 2 (molar ratio), at a frequency of 40 Hz and a voltage of Rise time 1.5 microseconds, fall time 1.5 microseconds, pulse duration 20 microseconds, 30°C, atmospheric pressure, processing density 300W·min / m 2 glow discharge surface treatment. Table 1 shows the measurement results of the surface composition after the surface treatment.

[0152] Next, 2.8 wt. parts, diluted with toluene to prepare a coating solution with a resin concentration of 10% by mass. This coating solution was applied on the surface-treated surface of the above-mentioned ETFE film with a bar coater, and dried in an oven at 60° C. for 30 minutes to form a coating film. The dry mass of the coating film is 1g / m 2 , with a film thickness of 1 μm.

[0153] The ETFE film with the coating film was set in a sputtering device (manufactu...

Abstract

Provided is a layered product that has excellent weather resistance, excellent moisture-proofing characteristics, and excellent interlayer adhesion, and in which the interlayer adhesion exhibits long-term stability. Also provided is a process for producing the layered product. The disclosed layered product comprises: a substrate sheet containing a fluorine-containing resin; an adhesion layer containing an acrylic resin; and a moisture-proofing layer containing, as the main component thereof, at least one type of inorganic compound selected from the group consisting of inorganic oxides, inorganic nitrides, and inorganic oxide-nitrides; wherein the sheet and the layers are laminated in the aforementioned order. The surface of the fluorine-containing resin sheet that is in contact with the adhesion layer has a superficial composition (measured by X-ray photoelectron spectroscopy) in which the atomic percentage of nitrogen is 0.2-3.0 at.% inclusive and the atomic percentage of oxygen is 1.0-5.0 at.% inclusive.

Description

technical field [0001] This invention relates to the laminated body which can be used as the protective sheet for solar cell modules, and its manufacturing method. Background technique [0002] In recent years, from the viewpoint of global environmental protection, more secure clean energy has been expected. Among the clean energy expected in the future, especially solar cells are expected to be higher and higher due to their cleanliness, safety, and ease of handling. [0003] The heart of a solar cell that converts sunlight into electrical energy is a cell (cell), and cells made of single crystal, polycrystalline, or amorphous silicon-based semiconductors are widely used. Usually, a plurality of batteries are connected in series or in parallel, and in order to maintain their functions for a long time, they are protected with various materials and used as solar battery modules. [0004] A solar cell module is usually structured like this: cover the side of the cell facing ...
