本発明の特徴及び利点を具現化する典型的な実施形態を、以下の説明において詳細に説明する。なお、本発明が異なる実施形態において様々な変更が可能であり、いずれも本発明の範囲を逸脱せず、ここの説明及び図示は、本質的に説明のために使用され、本発明を限定するものではないと理解すべきである。   Exemplary embodiments embodying features and advantages of the invention are described in detail in the following description. It should be noted that the present invention is capable of various modifications in different embodiments, all of which do not depart from the scope of the present invention, and the description and illustration herein are used essentially for explanation and limit the present invention. It should be understood that it is not a thing.

本発明の一実施形態は、曲面太陽光発電ユニットの製造方法を提供し、前記方法によれば、直接的に太陽光発電ユニットの各層を一体に成形して、所望の曲面状を得ることができ、別々に成形してから積層を行う煩雑な手順を回避し、工程を簡略化し、コストを低減し、時間を節約する。   One embodiment of the present invention provides a method for manufacturing a curved photovoltaic power generation unit.

The center is located below (in the direction shown) the back plate layer 11, and the center of the arc of the arc 32 is located above the surface layer 15. The arc body 32 is connected to the arc body 31 and the arc body 33 via two end surfaces (extended surfaces of two end points of the arc), respectively.

一実施形態では、表面層１５及びバックプレート層１１又は表面層１５若しくはバックプレート層１１のいずれか一方に押出金型を設けることで、平面型太陽光発電ユニットがホットプレス工程に曲面体になるよう押出されるようにする。   In one embodiment, by providing an extrusion die in the surface layer 15 and the back plate layer 11 or any one of the surface layer 15 or the back plate layer 11, the flat-type solar power generation unit becomes a curved body in the hot pressing process.

一実施形態では、アーチ状の曲面体は円弧体であってもよく、円弧体の曲面の一部又は全部は円弧面であり、円弧体の円弧の円心は表面層１５の側に位置してもよいが、バックプレート層１１の側に位置してもよい（図２参照）。   In one embodiment, the arched curved body may be an arc, and a part or all of the curved surface of the arc is an arc, and the center of the arc of the arc is located on the side of the surface layer 15. Alternatively, it may be located on the side of the back plate layer 11 (see FIG. 2).

一実施形態では、表面層１５上及びバックプレート層１１下に互いに平行な複数の押出金型を設け、表面層１５上の押出金型とバックプレート層１１上の押出金型とは太陽光発電ユニットの長手方向に沿って交互に配置される。   In one embodiment, a plurality of extrusion dies parallel to each other are provided on the surface layer 15 and below the back plate layer 11, and the extrusion dies on the surface layer 15 and the extrusion dies on the back plate layer 11 The units are arranged alternately along the longitudinal direction.

一実施形態では、押出金型は円柱体であってもよく、例えば、ホットプレス処理を開始する前に、円柱体を直接表面層１５上に置き、又はシリカゲル袋を介して表面層１５上に置き、円柱体の円弧面は表面層１５又はシリカゲル袋と互いに接するように保持され、ホットプレス工程が行われることに伴い、平面型太陽光発電ユニットの各層が軟化し、表面層１５が円弧面と互いに接する状態から徐々に一部の円弧面を包み、したがって、平面型太陽光発電ユニットが円弧体になるよう押出される。   In one embodiment, the extrusion mold may be a cylinder, for example, placing the cylinder directly on the surface layer 15 before starting the hot pressing process, or on the surface layer 15 via a silica gel bag. Place, the arc surface of the cylindrical body is held so as to be in contact with the surface layer 15 or the silica gel bag, and each layer of the flat type solar power generation unit is softened by the hot pressing process, and the surface layer 15 becomes an arc surface. From the state of contact with each other, a part of the arc surface is gradually wrapped, so that the flat photovoltaic power generation unit is extruded into an arc shape.

一実施形態では、円柱体２０は中実の円柱であってもよいが、中空の円筒であってもよく、好ましくはステンレス材質であり、例えば、ステンレス円柱、又は円柱状のステンレス金型であってもよい。   In one embodiment, the cylindrical body 20 may be a solid cylinder, but may be a hollow cylinder, and is preferably made of a stainless material, for example, a stainless steel cylinder or a cylindrical stainless steel mold. You may.

一実施形態では、透光層１５及びバックプレート層１１上に互いに平行な１つ又は複数の押出金型をそれぞれ設け、平面型太陽光発電ユニット１０がホットプレス過程で波状になるよう押出されるようにすることができる。例えば、図４を参照して、表面層１５上に１つの円柱体２０を設け、バックプレート層１１上に２つの円柱体を設けることができ、３つの円柱体は平行に設けられ、且つ太陽光発電ユニットの長手方向に沿って配置され、バックプレート層１１上の２つの円柱体は表面層１５上の円柱体２０の両側にそれぞれ位置する。即ち、表面層１５上の円柱体２０の投影はバックプレート層１１上の２つの円柱体の投影の間に位置する。したがって、押出処理後に得られる円弧体３１、円弧体３２、円弧体３３が全体的に波状に分布する。   In one embodiment, one or more extrusion dies parallel to each other are provided on the translucent layer 15 and the back plate layer 11, respectively, and the flat-type solar power generation unit 10 is extruded into a wave shape in a hot pressing process.

The three cylinders are provided in parallel, and Arranged along the longitudinal direction of the photovoltaic unit, the two cylinders on the back plate layer 11 are located on both sides of the cylinder 20 on the surface layer 15. That is, the projection of the cylinder 20 on the surface layer 15 is located between the projections of the two cylinders on the backplate layer 11. Therefore, the arc-shaped body 31, the arc-shaped body 32, and the arc-shaped body 33 obtained after the extrusion processing are distributed in a wave shape as a whole.

The upper and lower two layers of silica gel plate of the silica gel bag 40 have a groove sealing structure, and a bleed valve is provided at a side portion, and the silica gel bag 40 can be bleed by being connected to an external pipeline.

一実施形態では、平面型太陽光発電ユニット１０を加熱押出する前に予熱脱気を行う。表面層材料、例えばＰＣプレート材自体が水蒸気を吸収するため、予熱脱気によってプレート材内部の水蒸気を効果的に除去できるが、加熱押出時に水蒸気を除去すると、成形後の製品に気泡及び霧状の細孔群が発生し、太陽光発電ユニットの外観に影響する。   In one embodiment, preheating deaeration is performed before the flat type solar power generation unit 10 is heated and extruded. Since the surface layer material, for example, the PC plate material itself absorbs water vapor, the water vapor inside the plate material can be effectively removed by preheating degassing. Of fine pores are generated, which affects the appearance of the solar power generation unit.

一実施形態では、予熱脱気段階の加熱温度は１１０〜１３０℃であり、時間は５〜１５分であり、例えば１０分である。   In one embodiment, the heating temperature of the preheating degassing stage is 110-130 ° C and the time is 5-15 minutes, for example, 10 minutes.

以下、具体的な実施例を通じて本発明の一実施形態の曲面太陽光発電ユニットの製造方法をさらに説明する。   Hereinafter, a method for manufacturing a curved solar power generation unit according to an embodiment of the present invention will be further described through specific examples.

（平面型太陽光発電ユニットの製造）

The PET plate having the aluminum film is used as the back plate layer 11, and the back plate layer 11 is bonded to the lower surface of the flexible copper indium gallium selenium chip via the POE film. A PC plate having a thickness of 2 mm having a UV-resistant coating is used as the light-transmitting layer 15, and the surface layer 15 is adhered to the upper surface of the flexible copper indium gallium selenium chip via a UV-resistant POE film having a thickness of 0.2 mm. / First film layer 12 / photovoltaic power chip 13 / second film layer 14 / surface layer 15 "to form a planar photovoltaic power generation unit.

ここで、ＰＥＴプレート、フレキシブル銅インジウムガリウムセレンチップ及びＰＣプレートはいずれも平面プレートであり、したがって、形成される平面型太陽光発電ユニット１０が略立方体状となる。   Here, the PET plate, the flexible copper indium gallium selenium chip, and the PC plate are all flat plates, and thus the formed flat photovoltaic power generation unit 10 has a substantially cubic shape.

（準備段階）
立方体状の平面型太陽光発電ユニット１０を位置決めに従って上下２層のシリカゲルプレートにより密閉可能な１つのシリカゲル袋４０内に置く。シリカゲル袋４０は上下２層のシリカゲルプレートの四方に溝シール構造を有し、辺部に抽気弁が設けられ、外部管路と連結することで、シリカゲル袋４０に対して抽気を行うことができる。
抽気弁によりシリカゲル袋４０に対して抽気を行うことで、シリカゲル袋４０内部が負圧状態になるようにし、シリカゲル袋４０内部の真空度が１００Ｐａ未満になった後、抽気弁をオフにし、シリカゲル袋４０をホットプレス機の内部に押し込み、ホットプレス機の内部の抽気管路と連結させる。その後の全体のホットプレス段階において、シリカゲル袋４０に対して持続的に抽気処理を行う。 (Preparation stage)
The cubic planar solar power generation unit 10 is placed in one silica gel bag 40 that can be sealed with two upper and lower layers of silica gel plates according to the positioning.

By performing bleeding on the silica gel bag 40 by the bleed valve, the inside of the silica gel bag 40 is brought into a negative pressure state, and after the degree of vacuum inside the silica gel bag 40 becomes less than 100 Pa, the bleed valve is turned off, and the silica gel is turned off. The bag 40 is pushed into the inside of the hot press machine and connected to the bleeding line inside the hot press machine. In the subsequent overall hot pressing stage, the silica gel bag 40 is continuously subjected to the bleeding process.

ここで、ホットプレス機は電気加熱及び送風を制御する方式で、シリカゲル袋４０内の平面型太陽光発電ユニットに対する加熱処理を実現する。   Here, the hot press implements a heating process for the flat photovoltaic power generation unit in the silica gel bag 40 by a method of controlling electric heating and blowing.

（ホットプレス段階）
１）予熱脱気段階
ホットプレス機の内部温度を１１０〜１２０℃の範囲内に維持し、持続時間は１０分である。 (Hot press stage)
1) Preheating deaeration stage The internal temperature of the hot press is maintained within a range of 110 to 120 ° C, and the duration is 10 minutes.

２）持続加熱段階
ホットプレス機の内部温度を１４０〜１５０℃の範囲内に上昇させ、３０〜５０分間維持する。この間、第１のフィルム層１２、第２のフィルム層１４に熱融着が発生し、表面層１５が軟化し、したがって、平面型太陽光発電ユニット１０の各層が効果的に接着される。 2) Continuous heating stage The internal temperature of the hot press is raised within a range of 140 to 150 ° C. and maintained for 30 to 50 minutes. During this time, heat fusion occurs between the first film layer 12 and the second film layer 14, and the surface layer 15 is softened, so that the respective layers of the flat photovoltaic power generation unit 10 are effectively bonded.

３）波形成形段階
温度を１４０〜１５０℃の範囲内に維持し、平面型太陽光発電ユニット１０の平面状の表面層１５上に平滑面のステンレス円柱を１本置き、平面状のバックプレート層１１下に平滑面のステンレス円柱を２本設けて正確な位置決めを行う。上記ステンレス円柱はいずれもシリカゲル袋４０の外部に設けられる。液圧又はモーターの駆動下で平面型太陽光発電ユニット１０に対して押出処理を行い、太陽光発電ユニットが所定の波形通りに成形される。 3) Wave forming step The temperature is maintained in the range of 140 to 150 ° C., and one stainless steel cylinder having a smooth surface is placed on the flat surface layer 15 of the flat solar power generation unit 10, and the flat back plate layer is formed.

Extrusion processing is performed on the planar photovoltaic power generation unit 10 under hydraulic pressure or driving of a motor, and the photovoltaic power generation unit is formed into a predetermined waveform.

又は、ホットプレス機内に上下２列のステンレス金型を設け、正確な位置決め後に、液圧又はモーターの駆動下で平面型太陽光発電ユニットに対して押出処理を行うことができ、太陽光発電ユニットが所定の波形通りに成形される。   Alternatively, two rows of stainless steel molds are provided in the hot press machine, and after accurate positioning, extrusion processing can be performed on the flat type solar power generation unit under hydraulic pressure or driving of a motor. Are shaped according to a predetermined waveform.

また、上述した２つの方式を組み合わせることもでき、平面型太陽光発電ユニット１０は所定の波形通りに成形される。   In addition, the above-described two methods can be combined, and the flat-type solar power generation unit 10 is formed according to a predetermined waveform.

４）冷却送出段階
ホットプレス機の内部温度を６０〜７０℃の範囲まで下げ、５〜１０分間維持する。温度が６０℃未満になった後、シリカゲル袋４０の抽気弁をオフにし、シリカゲル袋４０をホットプレス機から押し出し、室温まで冷却した後、シリカゲル袋４０を開け、波形太陽光発電ユニットのホットプレス処理が完了し、３つの円弧体からなる波状の太陽光発電ユニットが得られる。ここで、各円弧体の角度はいずれも６０°である。 4) Cooling delivery stage The internal temperature of the hot press is reduced to the range of 60-70 ° C and maintained for 5-10 minutes. After the temperature falls below 60 ° C., the bleed valve of the silica gel bag 40 is turned off, the silica gel bag 40 is extruded from a hot press machine, and after cooling to room temperature, the silica gel bag 40 is opened, and the hot pressing of the corrugated solar power generation unit is performed. The processing is completed, and a corrugated solar power generation unit including three arcs is obtained. Here, the angle of each arc is 60 °.

（接続箱の取り付け、電力試験）
ホットプレス終了後の波形太陽光発電ユニットに対して外観検査を行ってから接続箱を取り付け、電力試験、絶縁試験後に包装して保存する。 (Mounting of connection box, power test)
After performing a visual inspection on the corrugated photovoltaic power generation unit after completion of hot pressing, a connection box is attached, and after a power test and an insulation test, packaging and storage are performed.

本実施例の具体的な製造フローは、予熱脱気段階の温度が１２０〜１３０℃であり、１つの円柱体を押出金型として使用してアーチ状の太陽光発電ユニットを得る。ここで、アーチ状が円弧状となり、円弧の角度がいずれも１２０°であることを除いて、実施例１と同様である。   In the specific production flow of the present embodiment, the temperature in the preheating deaeration stage is 120 to 130 ° C., and an arc-shaped photovoltaic power generation unit is obtained by using one cylinder as an extrusion die. Here, it is the same as the first embodiment except that the arch shape becomes an arc shape and the angle of each arc is 120 °.

本実施例の具体的な製造フローは、予熱脱気段階の温度が９０〜１００℃であることを除いて、実施例１と同様である。   The specific manufacturing flow of the present embodiment is the same as that of Embodiment 1 except that the temperature in the preheating deaeration stage is 90 to 100 ° C.

本実施例の具体的な製造フローは、予熱脱気を行わないで直接的に持続加熱段階へ進むことを除いて、実施例１と同様である。   The specific manufacturing flow of the present embodiment is the same as that of Embodiment 1 except that the process directly proceeds to the continuous heating stage without performing preheating degassing.

本実施例の具体的な製造フローは、持続加熱段階、波形成形段階の温度が１５０〜１６０℃であることを除いて、実施例１と同様である。   The specific manufacturing flow of this example is the same as that of Example 1 except that the temperature in the continuous heating step and the waveform forming step is 150 to 160 ° C.

本実施例の具体的な製造フローは、持続加熱段階、波形成形段階の温度が１８０〜１９０℃であることを除いて、実施例１と同様である。   The specific manufacturing flow of this example is the same as that of Example 1 except that the temperature in the continuous heating step and the waveform forming step is 180 to 190 ° C.

本実施例の具体的な製造フローは、冷却押出段階の温度が７０〜８０℃であることを除いて、実施例１と同様である。   The specific manufacturing flow of this example is the same as that of Example 1 except that the temperature of the cooling extrusion step is 70 to 80 ° C.

本実施例の具体的な製造フローは、冷却を行わないで、成形後のユニットが直接的に送出されることを除いて、実施例１と同様である。   The specific manufacturing flow of this embodiment is the same as that of the first embodiment except that the unit after molding is directly sent out without cooling.

本実施例の具体的な製造フローは、冷却送出段階の温度が４０〜５０℃であることを除いて、実施例１と同様である。   The specific manufacturing flow of this embodiment is the same as that of Embodiment 1 except that the temperature in the cooling and sending stage is 40 to 50 ° C.

実施例１〜９において得られた曲面太陽光発電ユニットをＡＭ１．５、１０００Ｗ／ｍ２、２５℃のＳＴＣで光電変換効率の試験を行うと、具体的な結果は表１に示すようである。   When a test of photoelectric conversion efficiency was performed on the curved solar power generation units obtained in Examples 1 to 9 at STC of AM 1.5, 1000 W / m 2, and 25 ° C., specific results are shown in Table 1.

表１の結果から分かるように、実施例１、２、５、７の光電変換効率は実施例３、４、６、８、９より優れている。これは、実施例３は、予熱脱気段階の温度が比較的低いため、効果的に脱気を行うことができず、したがって、得られる太陽光発電ユニットに肉眼で見える細孔が存在し、太陽光発電ユニットの透光率に影響し、さらに太陽光発電ユニットの光電変換効率に影響するからである。   As can be seen from the results in Table 1, the photoelectric conversion efficiencies of Examples 1, 2, 5, and 7 are superior to Examples 3, 4, 6, 8, and 9. This is because Example 3 cannot perform degassing effectively because the temperature of the preheating degassing stage is relatively low, and therefore, the resulting solar power generation unit has macroscopic pores, This is because it affects the transmittance of the solar power generation unit and further affects the photoelectric conversion efficiency of the solar power generation unit.

実施例４は、予熱脱気を行っていないため、実施例３の太陽光発電ユニットよりさらに多くの細孔が存在し、これに応じて光電変換効率がさらに低い。   In Example 4, since preheating and degassing were not performed, more pores were present than in the solar power generation unit of Example 3, and the photoelectric conversion efficiency was correspondingly lower.

実施例６は、持続加熱段階、波形成形段階の温度が高すぎるため、透光層、フィルム層に歪みが発生しやすく、フィルムが他の層から剥離しやすく、したがって、太陽光発電ユニット全体の信頼性が悪くなり、それとともに、歪みは太陽光発電ユニットの透光率にも影響し、さらに光電変換効率に影響する。   In Example 6, the temperature of the continuous heating step and the waveform forming step were too high, so that the light-transmitting layer and the film layer were easily distorted, and the film was easily peeled off from other layers. The reliability is deteriorated, and at the same time, the distortion affects the light transmittance of the solar power generation unit and further affects the photoelectric conversion efficiency.

実施例８の太陽光発電ユニットは、冷却を行わず、成形後のユニットが直接的に送出されるため、外部のガスが吹き返してユニットのエッジに気泡が形成されやすく、各層のエッジが剥離されやすい。したがって、太陽光発電ユニット全体の信頼性が悪くなり、一方、ユニットの透光率にも影響し、さらに光電変換効率に影響する。   In the photovoltaic power generation unit of Example 8, since the unit after molding is directly sent without cooling, the external gas is blown back and bubbles are easily formed at the edge of the unit, and the edge of each layer is peeled off. Cheap. Therefore, the reliability of the entire photovoltaic power generation unit deteriorates, and on the other hand, it also affects the light transmittance of the unit and further affects the photoelectric conversion efficiency.

実施例９は、冷却送出段階の温度が比較的低いため、太陽光発電ユニットの降温が比較的速く、フィルムの変形を引き起こしやすく、さらに太陽光発電ユニットの光電変換効率に影響する。   In the ninth embodiment, since the temperature in the cooling and sending stage is relatively low, the temperature of the photovoltaic power generation unit falls relatively quickly, the film is easily deformed, and the photoelectric conversion efficiency of the photovoltaic power generation unit is affected.
