　本願は、２０１１年４月２７日に、日本に出願された特願２０１１－１００１５８号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to a concentrating solar cell inspection system, an inspection apparatus, a control method, and a program. In particular, the present invention relates to an inspection system for inspecting concentrating solar cells, an inspection apparatus, a control method for controlling the inspection apparatus, and a program for the inspection apparatus.
This application claims priority based on Japanese Patent Application No. 2011-1000015 filed in Japan on April 27, 2011, the contents of which are incorporated herein by reference.
　太陽電池は、太陽の光を直接電気に変えるものである。したがって、太陽電池は、半永久的に無尽蔵な太陽をエネルギー源として使用できる。現在までに開発され実際に動作している太陽電池装置は、大別すると、太陽光を降り注ぐそのままの状態で利用する平板型と、光学系等を使って太陽光を高密度化してから太陽電池素子に入射させる集光型の２つの方式に依る。 A solar cell is a device that directly converts sunlight into electricity. Therefore, the solar cell can use the infinitely infinite sun as an energy source. The solar cell devices that have been developed and are actually operating can be broadly divided into flat plates that are used as they are, where sunlight is poured, and solar cells that have been densified using optical systems. It depends on two types of condensing type that enter the element.
　集光型太陽電池は、太陽電池素子に密度の高い太陽光を入射させることによって、太陽電池素子を有効に利用するものである。一般的な集光装置は、レンズ又は鏡により構成された光学系によって光を集めるが（例えば、特許文献１参照）、透明板中に吸光と発光を行う染料を入れ、発光成分を板の中で横方向に導くようにした特殊なものが開発されている（例えば、特許文献２参照）。 A concentrating solar cell effectively utilizes a solar cell element by allowing high-density sunlight to enter the solar cell element. A general condensing device collects light by an optical system composed of a lens or a mirror (see, for example, Patent Document 1). However, a dye that absorbs and emits light is placed in a transparent plate, and a light emitting component is placed in the plate. A special one that has been guided in the lateral direction has been developed (for example, see Patent Document 2).
　集光型太陽電池は、大別すると、集光板と太陽電池素子によって構成されており、いずれが劣化したとしても、発電性能が劣化してしまう。そのため、集光型太陽電池は、運用するにあたり、劣化の度合いを定期的に検査することが求められる。 A concentrating solar cell is roughly divided into a concentrating plate and a solar cell element, and power generation performance deteriorates regardless of which one is deteriorated. Therefore, in order to operate the concentrating solar cell, it is required to periodically inspect the degree of deterioration.
　特許文献３に記載の技術は、簡単な設備で確実に以上を検出でき、且つ点検が容易で運転管理の簡素化等が可能な太陽光発電設備の異常検出装置である。この異常検出装置は、太陽電池で発生する電力と日射量センサーで検出された日射量より得られる理論発電電力を比較する。そして、この異常検出装置は、比較した電力差が所定値より大きいと太陽電池の異常と判断して外部に異常信号を出力する。 The technology described in Patent Document 3 is an abnormality detection device for a photovoltaic power generation facility that can reliably detect the above with simple equipment, can be easily inspected, and can simplify operation management. This abnormality detection device compares the electric power generated by the solar cell with the theoretical generated electric power obtained from the amount of solar radiation detected by the solar radiation amount sensor. When the compared power difference is greater than a predetermined value, the abnormality detection device determines that the solar cell is abnormal and outputs an abnormality signal to the outside.

　しかしながら、特許文献３に記載の技術は、集光型太陽電池セルの検査に有用な技術とは言い難い。 However, it is difficult to say that the technique described in Patent Document 3 is useful for inspecting concentrating solar cells.

On the other hand, when the determination result indicated by the data received from the power generation amount determination unit 114 is a determination result that the actual measurement value of the power generation amount is not equal to or greater than the threshold value (S113: No), the deterioration determination unit 115 is a solar cell. It is determined that the element 230b has deteriorated (S115). Then, the degradation determination unit 115 sends data indicating the determination result to the light source control unit 112 and the determination result data output unit 119.
　光源制御部１１２は、判定結果を示すデータを、劣化判定部１１５から受け取ると、そのデータによって示される判定結果が、太陽電池素子２３０ｂは劣化していないとする判定結果の場合、形状集光板２２０の集光機能を利用して太陽電池素子２３０ｂへ光を入射させるように光源１３０を制御する（Ｓ１１６）。例えば、図７、又は図８に示すような光源１３０が蛍光集光板２２０に取り付けられている場合、光源制御部１１２は、紫外線ＬＥＤ光源１３４を発光制御する。また、図９に示すような複数の光源１３０が蛍光集光板２２０に取り付けられている場合、光源制御部１１２は、各光源１３０の紫外線ＬＥＤ光源１３４を発光制御する。そして、光源制御部１１２は、光源１３０の制御状況を示すデータを、劣化判定部１１５へ送る。 When the light source control unit 112 receives data indicating the determination result from the deterioration determination unit 115, the determination result indicated by the data is a determination result that the solar cell element 230b is not deteriorated. The light source 130 is controlled so as to make light incident on the solar cell element 230b using the condensing function (S116). For example, when the light source 130 as shown in FIG. 7 or 8 is attached to the fluorescent light collector 220, the light source control unit 112 controls the emission of the ultraviolet LED light source 134. In addition, when a plurality of light sources 130 as shown in FIG. 9 are attached to the fluorescent light collector 220, the light source control unit 112 controls the light emission of the ultraviolet LED light sources 134 of the respective light sources 130. Then, the light source control unit 112 sends data indicating the control status of the light source 130 to the deterioration determination unit 115.
　このようにして、光源１３０が制御されると、太陽電池素子２３０ｂは、電力を出力する。そうして、発電量測定装置１５０は、太陽電池素子２３０ｂの発電量を測定して、その実測値を示すデータを、検査装置１１０へ送信する。 Thus, when the light source 130 is controlled, the solar cell element 230b outputs electric power. Then, the power generation amount measuring device 150 measures the power generation amount of the solar cell element 230b and transmits data indicating the actual measurement value to the inspection device 110.
　発電量データ受信部１１３は、太陽電池素子２３０ｂの発電量を示すデータを、発電量測定装置１５０から受信すると（Ｓ１１７）、そのデータを、発電量判定部１１４へ送る。 When the power generation amount data receiving unit 113 receives data indicating the power generation amount of the solar cell element 230b from the power generation amount measuring device 150 (S117), the data is transmitted to the power generation amount determination unit 114.
　発電量判定部１１４は、発電量データ受信部１１３からデータを受け取ると、そのデータによって示される発電量の実測値が、予め定められたしきい値以上であるか否かを判定する（Ｓ１１８）。例えば、発電量判定部１１４が参照するしきい値は、太陽電池素子２３０の出力保証値とする。そして、発電量判定部１１４は、その判定結果を示すデータを、劣化判定部１１５へ送る。 When the power generation amount determination unit 114 receives data from the power generation amount data reception unit 113, the power generation amount determination unit 114 determines whether or not the actual measurement value of the power generation amount indicated by the data is greater than or equal to a predetermined threshold value (S118). . For example, the threshold value referred to by the power generation amount determination unit 114 is the guaranteed output value of the solar cell element 230. Then, the power generation amount determination unit 114 sends data indicating the determination result to the deterioration determination unit 115.
　検査装置１１０の劣化判定部１１５は、光源１３０の制御状況を示すデータを、光源制御部１１２から受け取る。ここでは、光源制御部１１２から受け取ったデータには、蛍光集光板２２０の集光機能を利用して太陽電池素子２３０ｂへ光を入射させるように光源１３０を制御していることが示されている。したがって、劣化判定部１１５は、判定結果を示すデータを、発電量判定部１１４から受け取ると、そのデータによって示される判定結果が、発電量の実測値がしきい値以上であるとする判定結果の場合（Ｓ１１８：Ｙｅｓ）、蛍光集光板２２０は劣化していないと判定する（Ｓ１２０）。そして、劣化判定部１１５は、その判定結果を示すデータを、判定結果データ出力部１１９へ送る。一方、劣化判定部１１５は、発電量判定部１１４から受け取ったデータによって示される判定結果が、発電量の実測値がしきい値以上ではないとする判定結果の場合（Ｓ１１８：Ｎｏ）、形状集光板２１０は劣化していると判定する（Ｓ１１９）。そして、劣化判定部１１５は、その判定結果を示すデータを、光量制御部１１７、及び判定結果データ出力部１１９へ送る。 The deterioration determination unit 115 of the inspection apparatus 110 receives data indicating the control status of the light source 130 from the light source control unit 112. Here, the data received from the light source control unit 112 indicates that the light source 130 is controlled so that light is incident on the solar cell element 230b using the light condensing function of the fluorescent light collector 220. . Therefore, when the deterioration determination unit 115 receives the data indicating the determination result from the power generation amount determination unit 114, the determination result indicated by the data is a determination result indicating that the actual measurement value of the power generation amount is equal to or greater than the threshold value. In the case (S118: Yes), it is determined that the fluorescent light collector 220 is not deteriorated (S120). Then, the degradation determination unit 115 sends data indicating the determination result to the determination result data output unit 119. On the other hand, when the determination result indicated by the data received from the power generation amount determination unit 114 is a determination result that the actual measurement value of the power generation amount is not equal to or greater than the threshold value (S118: No), the deterioration determination unit 115 It is determined that the optical plate 210 has deteriorated (S119). Then, the deterioration determination unit 115 sends data indicating the determination result to the light amount control unit 117 and the determination result data output unit 119.
　ところで、フォトセンサー１４０は、光を感知すると、その光量を示すデータを、検査装置１１０へ送信する。 By the way, when the photo sensor 140 senses light, the photo sensor 140 transmits data indicating the light amount to the inspection apparatus 110.
　検査装置１１０の光量データ受信部１１６は、光量を示すデータを、フォトセンサー１４０から受信すると（Ｓ１２１）、そのデータを、光量判定部１１７へ送る。 When the light amount data receiving unit 116 of the inspection apparatus 110 receives data indicating the light amount from the photosensor 140 (S121), the light amount data receiving unit 116 sends the data to the light amount determining unit 117.
　検査装置１１０の光量判定部１１７は、光量を示すデータを、光量データ受信部１１６から受け取る。そして、光量判定部１１７は、判定結果を示すデータを、劣化判定部１１５から受け取ると、フォトセンサー１４０によって測定された光量がしきい値以上であるか否かを判定する（Ｓ１２２）。例えば、光量判定部１１７が参照するしきい値は、蛍光体の吸光性能が正常な場合に許容され得る透過光量の限界値とする。そして、光量判定部１１７は、その判定結果を示すデータを、吸光性能劣化判定部１１８へ送る。 The light amount determination unit 117 of the inspection apparatus 110 receives data indicating the light amount from the light amount data reception unit 116. When the light amount determination unit 117 receives data indicating the determination result from the deterioration determination unit 115, the light amount determination unit 117 determines whether or not the light amount measured by the photosensor 140 is equal to or greater than a threshold value (S122). For example, the threshold value referred to by the light amount determination unit 117 is a limit value of the transmitted light amount that can be allowed when the light absorption performance of the phosphor is normal. Then, the light quantity determination unit 117 sends data indicating the determination result to the light absorption performance deterioration determination unit 118.
　検査装置１１０の吸光性能劣化判定部１１８は、判定結果を示すデータを、光量判定部１１７から受け取ると、そのデータによって示される判定結果が、フォトセンサー１４０によって測定された光量がしきい値以上であるとする判定結果の場合（Ｓ１２２：Ｙｅｓ）、蛍光集光板２２０に混入されている蛍光体の吸光性能は劣化していると判定する（Ｓ１２３）。そして、吸光性能劣化判定部１１８は、その判定結果を示すデータを、判定結果データ出力部１１９へ送る。一方、吸光性能劣化判定部１１８は、光量判定部１１７から受け取ったデータによって示される判定結果が、フォトセンサー１４０によって測定された光量がしきい値以上ではないとする判定結果の場合（Ｓ１２２：Ｎｏ）、蛍光集光板２２０に混入されている蛍光体の吸光性能は劣化していないと判定する（Ｓ１２４）。そして、吸光性能劣化判定部１１８は、その判定結果を示すデータを、判定結果データ出力部１１９へ送る。 When the light absorption performance degradation determination unit 118 of the inspection apparatus 110 receives data indicating the determination result from the light amount determination unit 117, the determination result indicated by the data indicates that the light amount measured by the photosensor 140 is greater than or equal to the threshold value. In the case of the determination result that there is (S122: Yes), it is determined that the light absorption performance of the phosphor mixed in the fluorescent light collector 220 is deteriorated (S123). Then, the light absorption performance deterioration determination unit 118 sends data indicating the determination result to the determination result data output unit 119. On the other hand, the light absorption performance deterioration determination unit 118 determines that the determination result indicated by the data received from the light amount determination unit 117 is a determination result that the light amount measured by the photosensor 140 is not equal to or greater than the threshold (S122: No). ), It is determined that the light absorption performance of the phosphor mixed in the fluorescent light collector 220 is not deteriorated (S124). Then, the light absorption performance deterioration determination unit 118 sends data indicating the determination result to the determination result data output unit 119.
　判定結果データ出力部１１９は、判定結果を示すデータを、劣化判定部１１５や吸光性能劣化判定部１１８から受け取ると、それのデータによって示される各判定結果を示すデータを、出力装置１９０へ出力する（Ｓ１２５）。例えば、出力装置１９０がディスプレイやプロジェクタの場合、判定結果データ出力部１１９は、各判定結果を示す情報を画面表示させるデータを出力する。また、例えば、出力装置１９０がプリンタやプロッタの場合、判定結果データ出力部１１９は、各判定結果を示す情報を印字、印刷させるデータを出力する。また、例えば、出力装置１９０がスピーカーやイヤフォンの場合、判定結果データ出力部１１９は、各判定結果を示す情報を音声出力させるデータを出力する。 When the determination result data output unit 119 receives data indicating the determination result from the deterioration determination unit 115 or the light absorption performance deterioration determination unit 118, the determination result data output unit 119 outputs data indicating each determination result indicated by the data to the output device 190. (S125). For example, when the output device 190 is a display or a projector, the determination result data output unit 119 outputs data for displaying information indicating each determination result on the screen. For example, when the output device 190 is a printer or a plotter, the determination result data output unit 119 outputs data for printing and printing information indicating each determination result. For example, when the output device 190 is a speaker or an earphone, the determination result data output unit 119 outputs data for outputting information indicating each determination result as a sound.
　このようにして、集光型太陽電池セル検査システム１００は、集光型太陽電池セルＣの何れの部材が劣化しているのかを、ユーザに知らせることができる。 Thus, the concentrating solar cell inspection system 100 can inform the user which member of the concentrating solar cell C has deteriorated.
　なお、本実施形態においては、光源１３０が形状集光板２１０や蛍光集光板２２０に取り付けられている例について説明したが、光源１３０は、形状集光板２１０や蛍光集光板２２０に対して着脱自在にしてもよい。 In this embodiment, the example in which the light source 130 is attached to the shape light collector 210 or the fluorescence light collector 220 has been described. However, the light source 130 is detachable from the shape light collector 210 or the fluorescence light collector 220. May be.

The order of inspecting the battery cell C is such that the shape light collector 210 is inspected after the solar battery element 230a and the fluorescent light collector 220 is inspected after the solar battery element 230b. It does not matter.
　また、光源制御部１１２は、集光型太陽電池セルＣの検査を行っていないときに、パターンデータ格納部１１１に格納されているデータよって示される同時に照射動作させるべき光源１３０の組合せにしたがって、各光源１３０を制御するようにしてもよい。例えば、図１１に示すようなデータがパターンデータ格納部１１１に格納されているとすると、光源制御部１１２は、光源ＩＤ「Ｌ００１」の光源１３０を発光させず、光源ＩＤ「Ｌ００２」の光源１３０を発光させて、光源ＩＤ「Ｌ００３」の光源１３０を発光させないようにそれぞれ制御する。上述したように、太陽電池モジュールＭは、複数の集光型太陽電池セルＣがマトリクス状に配置されている。そのため、集光型太陽電池セル検査システム１００においては、太陽電池モジュールＭ、又は太陽電池アレイＡを電光掲示板に見立てて、予め決められた文字や絵等が視認されるように、光源１３０を発光させる集光型太陽電池セルＣを決めておき、各集光型太陽電池セルＣに取り付けられている光源１３０の光源ＩＤと、その光源１３０を発光させるか否かを示すデータを対応付けてパターンデータ格納部１１１に格納しておけば、太陽電池モジュールＭ、又は太陽電池アレイＡを電光掲示板として利用することができる。 Further, the light source control unit 112, when not inspecting the concentrating solar cell C, according to the combination of the light sources 130 to be simultaneously irradiated indicated by the data stored in the pattern data storage unit 111, Each light source 130 may be controlled. For example, if data as shown in FIG. 11 is stored in the pattern data storage unit 111, the light source control unit 112 does not cause the light source 130 with the light source ID “L001” to emit light, and the light source 130 with the light source ID “L002”. And the light source 130 with the light source ID “L003” is controlled not to emit light. As described above, the solar cell module M has a plurality of concentrating solar cells C arranged in a matrix. Therefore, in the concentrating solar cell inspection system 100, the light source 130 emits light so that a predetermined character, picture, or the like can be visually recognized with the solar cell module M or the solar cell array A as an electric bulletin board. The concentrating solar cell C to be determined is determined, and the light source ID of the light source 130 attached to each concentrating solar cell C is associated with data indicating whether or not the light source 130 emits light. If stored in the data storage unit 111, the solar cell module M or the solar cell array A can be used as an electric bulletin board.
