本発明を図示の実施例に基づいて詳細に説明する。   The present invention will be described in detail based on the embodiments shown in the drawings.

図１は例えば建物の窓ガラスを兼ねた透過型太陽光発電装置の断面図を示している。ガラス、アクリル樹脂等から成る透明な裏面板１上に、中間部材として和紙等から成る透光性を有するシート状部材２と、平面的に配列した複数枚の結晶系の太陽電池セル３と、ガラス、アクリル樹脂等から成る透明な表面板４とが配置されている。各太陽電池セル３同士は図示しない電極、配線により電気的に接続され、外部の太陽電池取り出しケーブルに接続されている。また、太陽電池セル３の周囲には、ＥＶＡ、ＰＶＢ、シリコン等から成る電気絶縁性を持ち透明な絶縁材５が充填されている。   FIG. 1 shows a cross-sectional view of a transmission type solar power generation device that also serves as a window glass of a building, for example. On a transparent back plate 1 made of glass, acrylic resin or the like, a sheet-like member 2 having translucency made of Japanese paper or the like as an intermediate member, and a plurality of crystalline solar cells 3 arranged in a plane, A transparent surface plate 4 made of glass, acrylic resin or the like is disposed. The solar cells 3 are electrically connected to each other by electrodes and wiring (not shown) and are connected to an external solar battery take-out cable. In addition, the periphery of the solar battery cell 3 is filled with a transparent insulating material 5 made of EVA, PVB, silicon or the like and having an electrical insulating property.

表面板４側から入射した太陽光は、太陽電池セル３に作用して発電がなされると共に、太陽光が太陽電池セル３同士の隙間から裏面板１側の室内に採光される。そして、和紙等から成るシート状部材２を設けたことにより、太陽電池セル等の部品を隠すことができると共に、太陽光がシート状部材２を透過する際に、散乱して柔らかい光として裏面板側１に出射され、和紙が持つまだら模様を浮き立たせ、室内空間を和ませることができる。   The sunlight incident from the front plate 4 side acts on the solar cells 3 to generate power, and the sunlight is collected from the gaps between the solar cells 3 into the back plate 1 side of the room. And by providing the sheet-like member 2 made of Japanese paper or the like, it is possible to hide parts such as solar cells, and when the sunlight passes through the sheet-like member 2, the back plate is scattered as soft light. It is emitted to the side 1, and the mottled pattern of the Japanese paper can be raised to soften the indoor space.

また、シート状部材２に予め文字又は図柄又は模様等の画像、色彩を印刷、エンボス加工等を施しておけば、これらの文字又は図柄又は模様等の画像や色彩を表現することができる。なお、本実施例においては、和紙を用いたが、和紙以外に透光性を有する洋紙、合成樹脂製フィルムを用いてもよい。また、色彩等の異なる複数種のシート状部材２を用いて組み合わせることにより、模様等の画像、色彩を表現することもできる。   In addition, if images, colors, etc. of characters, designs, patterns, etc. are printed and embossed on the sheet-like member 2 in advance, images, colors, etc. of these characters, designs, patterns, etc. can be expressed. In this embodiment, Japanese paper is used. However, other than Japanese paper, translucent paper or synthetic resin film may be used. Further, by combining a plurality of types of sheet-like members 2 having different colors and the like, an image such as a pattern and colors can be expressed.

実施例１においては、太陽電池セル３同士の隙間から太陽光を採光し、室内空間を照明したが、本実施例２においては、図２に示すように透明な裏面板１上にシート状部材２、複数枚の太陽電池セル３を積層し、更に裏面に発光ダイオード１１を取り付けた表面板４が積層されている。なお、この発光ダイオード１１は太陽電池セル３同士の隙間から室内空間側に光を出射するように配置されている。実施例１と同様にシート状部材２、太陽電池セル３の周囲は透明な絶縁材５が充填されている。   In Example 1, sunlight was collected from the gap between the solar cells 3 to illuminate the indoor space. In Example 2, however, a sheet-like member is formed on the transparent back plate 1 as shown in FIG. 2. A surface plate 4 in which a plurality of solar cells 3 are stacked and a light emitting diode 11 is attached to the back surface is stacked. In addition, this light emitting diode 11 is arrange | positioned so that light may be radiate | emitted from the clearance gap between the photovoltaic cells 3 to the indoor space side. Similar to Example 1, the periphery of the sheet-like member 2 and the solar battery cell 3 is filled with a transparent insulating material 5.

この実施例２では、夜間において太陽電池セル３の隙間から照射された発光ダイオード１１により、太陽光と同様に、格子状に漏れた光によりシート状部材２を照明することができる。   In the second embodiment, the sheet-like member 2 can be illuminated with light leaking in a lattice pattern, similar to sunlight, by the light emitting diodes 11 irradiated from the gaps of the solar cells 3 at night.

なお、発光ダイオード１１を太陽電池セル３の裏面に配置すれば、シート状部材２を全面的に照明することもできる。   In addition, if the light emitting diode 11 is arrange | positioned on the back surface of the photovoltaic cell 3, the sheet-like member 2 can also be illuminated entirely.

そして、商用電源或いは太陽電池セル３により昼間発電した電気をバッテリに蓄電し、夜間に発光ダイオード１１により室内を照明する。   Then, electricity generated during the day by the commercial power source or the solar battery cell 3 is stored in the battery, and the room is illuminated by the light emitting diode 11 at night.

本実施例３においては、図３に示すように裏面板１上の透明絶縁板２１との間の空間部Ｓ内に、シート状部材２、発光ダイオード１１が配置され、発光ダイオード１１は透明絶縁板２１の裏側に取り付けられている。透明絶縁板２１上には、太陽電池セル３、表面板４が実施例１と同様に積層されている。また、空間部Ｓの周囲にはスペーサ２２が配置され、空間部Ｓ内は密閉状態とされ、窓ガラスに用いた際に断熱性・遮音性を向上させることができる。   In the third embodiment, as shown in FIG. 3, the sheet-like member 2 and the light emitting diode 11 are disposed in the space S between the back plate 1 and the transparent insulating plate 21, and the light emitting diode 11 is transparently insulated. It is attached to the back side of the plate 21. On the transparent insulating plate 21, the solar cells 3 and the surface plate 4 are laminated in the same manner as in the first embodiment. Moreover, the spacer 22 is arrange | positioned around the space part S, the inside of the space part S is made into a sealed state, and when it uses for a window glass, heat insulation and sound insulation can be improved.

この場合に、シート状部材２に例えば和紙等の紙を用いると、紙により太陽光や発光ダイオード１１からの光を柔らかい光に変換すると共に、紙の吸湿性により、空間部Ｓ内の湿気を吸湿し、結露等の発生を防止することができる。   In this case, when paper such as Japanese paper is used for the sheet-like member 2, sunlight and light from the light emitting diode 11 are converted into soft light by the paper, and moisture in the space portion S is reduced due to moisture absorption of the paper. It absorbs moisture and can prevent the occurrence of condensation.

実施例１〜３においては、中間部材として和紙等のシート状部材２を用いたが、中間部材として有色透明又は有色半透明なＥＶＡ、ＰＶＢ、シリコン等の絶縁材５を用いれば、シート状部材２を省略しても、屋内に色彩を表示することができる。   In Examples 1-3, the sheet-like member 2 such as Japanese paper was used as the intermediate member. However, if the insulating member 5 such as colored transparent or colored translucent EVA, PVB, or silicon is used as the intermediate member, the sheet-like member is used. Even if 2 is omitted, the color can be displayed indoors.

本実施例４においては、図４に示すように表面板４の裏面にアモルファス系の太陽電池セル３１を貼り付けると共に、太陽電池セル３１の隙間に発光ダイオード１１を配置している。なお、実施例３と同一の部材には同一の符号を付し説明は省略する。
アモルファス系の太陽電池セル３１は極めて薄いため、表面板４に直接貼り付けることができ、図３に示すような絶縁材５、絶縁板２１を用いる必要がなく、製造工程を短縮することができる。
本実施例４においても、裏面板１と表面板４の間に空間部Ｓが形成され、この空間部Ｓ内に、和紙等のシート状部材２を配置することにより、和紙により太陽光や発光ダイオード１１からの光を柔らかい光に変換すると共に、和紙の吸湿性により、空間部Ｓ内の湿気を吸湿し、結露等の発生を防止することができる。 In Example 4, as shown in FIG. 4, amorphous solar cells 31 are attached to the back surface of the front plate 4, and the light emitting diodes 11 are arranged in the gaps between the solar cells 31. In addition, the same code | symbol is attached | subjected to the member same as Example 3, and description is abbreviate | omitted.
Since the amorphous solar cells 31 are extremely thin, they can be directly attached to the surface plate 4, and it is not necessary to use the insulating material 5 and the insulating plate 21 as shown in FIG. 3, and the manufacturing process can be shortened. .
Also in the fourth embodiment, a space portion S is formed between the back plate 1 and the front plate 4, and by placing a sheet-like member 2 such as Japanese paper in the space portion S, sunlight or light is emitted by Japanese paper. Light from the diode 11 can be converted into soft light, and moisture in the space S can be absorbed by the hygroscopicity of Japanese paper, thereby preventing the occurrence of condensation.
