擬似太陽光照射装置の制御方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Application in Industry-A) The present invention relates to a method for controlling a simulated sunlight irradiation device, and in particular, a simulated sunlight irradiation device suitable for conducting characteristic tests of solar cells, etc. The present invention relates to a control method.
（従来の技術》
近年、パネル状の大型太陽電池の需要が高くなると共に

う擬似太陽光照射装置の開発が進められている。(Prior Art) In recent years, as the demand for large panel-shaped solar cells increases, the development of simulated sunlight irradiation devices for testing the characteristics of the solar cells, particularly measuring the maximum output, etc., is progressing.

性試験を行なうのは不可能である。In order to perform characteristic tests on large solar cells, high output power (e.g. 60 [
[kw] ) is required, but as is well known, there are currently no continuous lighting type lamps that necessarily generate the amount of incident light, and in fact, It is impossible to test the characteristics of large solar cells using continuously lit lamps.
そこで、従来においては、照射ランプとしてフラッシュ
ランプを用いている。Therefore, conventionally, a flash lamp is used as the irradiation lamp.

電位差を測定することににり行なう。For solar cell characteristics testing, for example, a variable resistance load is connected to the solar cell (test object), and the resistance value of the resistance load is changed while the irradiation lamp is lit to control the current flowing through the solar cell to a specified value. This is done by measuring the potential difference required for the solar cell in response to the current.

試験が行なわれる。Generally, while the irradiation lamp is lit to generate a scheduled amount of light, the resistance value of the resistive load is changed so that the current changes stepwise to about 64 to 128 different values, and each current value is A characteristic test is carried out by measuring the corresponding potential difference in each case.
（発明が解決しようとする問題点）
上記した従来の技術は、次のような問題点を有していた

。The lighting time of the flash lamp is usually 2 to 2Q [m5
ec]. During this lighting time, after the spectrum 1 to 1 of the simulated sunlight stabilizes, the resistance value of the resistive load connected to the solar cell is changed in 64 to 128 steps, and the resistance value is set to the target value. The time from when the target value is set until the next target value is set becomes extremely short, making it difficult to find the timing to measure the potential difference occurring in the solar cell.

イミングがざらにとりにくくなる。Also, the time from when the resistive load is changed until the current flowing through the solar cell stabilizes to a specified value, and the time from when the current stabilizes until the potential difference across the solar cell stabilizes, etc. Taking this into consideration, it becomes difficult to determine the timing of measuring the potential difference.

う懸念もある。Furthermore, it is sometimes necessary to measure the potential difference before the spectral distribution of the simulated sunlight has stabilized, or before the potential difference required for solar cells has stabilized. There is also a concern that the data obtained in solar cell characteristic tests conducted by 1Q may lack reliability.

おる。(Means and effects for solving the problems) In order to solve the above-mentioned problems, the present invention provides a pseudo sunlight irradiation device using a continuous lighting type irradiation lamp as the irradiation lamp. We have taken measures to control the irradiation lamp so that a current exceeding its rated current flows for a predetermined period of time while it is on, and as a result, the current can be controlled to flow at a constant rate for a longer period of time than with conventional simulated sunlight irradiation devices using flash lamps. The feature is that it is possible to irradiate a simulated amount of sunlight to easily and reliably test the characteristics of solar cells.

つぎに本発明による擬似太陽光照射装置の制御方法を、
第３図を用いて説明する。なお、以下の説明においては
、６０ ［ｋｗ］に近い擬似太陽光を出力することので
きる擬似太陽光照射装置の制御方法について説明する。Next, the method for controlling the simulated sunlight irradiation device according to the present invention is as follows.
This will be explained using FIG. In the following description, a method for controlling a simulated sunlight irradiation device that can output simulated sunlight close to 60 [kW] will be described.
まず、擬似太陽光照射装置の照射ランプとしては、定格
用ツノ３．６［ｋｗ］、定格電圧３０［Ｖ］、定格電流
１２０ ［Ａ］の連続点灯用の放電ランプを４灯用いる
。First, as the irradiation lamps of the simulated sunlight irradiation device, four discharge lamps for continuous lighting with a rated horn of 3.6 [kW], a rated voltage of 30 [V], and a rated current of 120 [A] are used.

いては、前記照射ランプ２全体の光出力は約５８ ［ｋ
ｗ］となる。Next, at a predetermined timing, the AC switching device 1
Turn on 6. By turning on the AC switching device 16, a current four times the rated current Ir of the irradiation lamp 2 flows through the irradiation lamp 2, and the light output of the irradiation lamp 2 also becomes about four times the rated output. That is, in this embodiment, the light output of the entire irradiation lamp 2 is approximately 58 [k
w].
この様子を第１図を用いて、ざらに詳細に説明する。第
１図は、照射ランプ２に流れる電流と時間との関係を示
すグラフである。This situation will be roughly explained in detail using FIG. FIG. 1 is a graph showing the relationship between the current flowing through the irradiation lamp 2 and time.

安定する。In FIG. 1, time T3 is elapsed after the irradiation lamp 2 is turned on.
When the AC switching device 16 is turned on, T

された。In this embodiment, the maximum time T max for which a current four times the rated current Ir can be made to flow through the irradiation lamp 2 without adversely affecting the irradiation lamp 2 is approximately 1 [sec]. This was confirmed through experiments conducted by the inventor.

特性試験を行なえば良い。In the past, the time ΔT2 during which a current of 4Ir could be stably passed through the irradiation lamp 2 for d3 was 990 m at maximum.
5 cc], and the characteristics test of the solar cell 8 may be performed within this time.
この結果、太陽電池に流れる電流を種々の値に制御して

来の擬似太陽光照射装置の制御方法に比べて格段に長く
なり、各電流値ごとの電位差の測定を確実に行なうこと
ができる。As a result, when controlling the current flowing through the solar cell to various values and measuring the potential difference generated in the solar cell for each current value, the current flowing through the solar cell must be stabilized at a certain current value before the next one. The time it takes for the current value to change to is much longer than in the conventional control method for the simulated sunlight irradiation device, and it is possible to reliably measure the potential difference for each current value.
もちろん、交流スイッチング装置１６をオンにする時間
（ΔＴ１＋ΔＴ２）は、必ずしもＴ ｍａｘでおる必要

。前記交流スイッチング装置１６の開閉時間の制御は、
既知の手法を用いて行なうことができるので、その説明
は省略する。Of course, the time (ΔT1+ΔT2) for turning on the AC switching device 16 does not necessarily have to be T max, but may be the minimum time that allows the test device 9 to reliably measure the potential difference for each current value. Good. Control of the opening/closing time of the AC switching device 16 is as follows:
Since this can be done using a known method, its explanation will be omitted.
この実施例においては、試験装置９により太陽電池８の
特性試験を行なわないときにおいても、照射ランプ２の
放電を持続しているので、交流スイッチング装置１６を

以上の値に安定し、かつ照射ランプ２め照射光のスペク
トルおよびその強度が安定するまでの時間ΔＴ１が、照
射ランプ２の放電を持続しない場合に比べて短くなる。In this embodiment, even when the characteristics test of the solar cell 8 is not performed using the test device 9, the discharge of the irradiation lamp 2 is continued, so that after the AC switching device 16 is turned on, The time ΔT1 until the current stabilizes to a value equal to or higher than the rated current and the spectrum and intensity of the second irradiation light from the irradiation lamp become stable is shorter than when the irradiation lamp 2 does not continue to discharge.
換言すれば、同一のＴ ｍａｘに対するΔＴ２の割合が
犬ぎくなる。したがって、試験装置９により太陽電池８
の特性試験を行なう時間を長くとることができる。In other words, the ratio of ΔT2 to the same T max becomes too large. Therefore, the solar cell 8 is
It is possible to take more time to conduct characteristic tests.
なお、定格電流以上の電流を複数回にわたって照射ラン
プに流す場合には、その電流を流す間隔（インターバル
）は必まり短くない方が良い。この実施例においては、
インターバルは１５［ＳｅＣ］以上とることが望ましい
。Note that when a current higher than the rated current is passed through the irradiation lamp multiple times, the intervals at which the current is passed should not necessarily be short. In this example,
It is desirable that the interval is 15 [SeC] or more.
また、交流スイッチング装置１６をオンにすることによ

れるものとして説明したが、本発明では特にこれのみに
限定されることはなく、４倍に満たない、あるいは４倍
＠超える電流が流れるにうにしても良いことは当然であ
る。Further, although the explanation has been made assuming that when the AC switching device 16 is turned on, a current four times the rated current flows through the irradiation lamp 2, the present invention is not limited to this. Of course, it is possible to allow a current less than twice as much or more than four times as much to flow.
