The photoelectric conversion characteristics of the solar cell, the photoexcited electric component, and the optical material photoelectric conversion element are measured by measuring the current electric power of the photoelectric conversion element under irradiation. In the measurement of the characteristics of the solar cell, the data on the horizontal axis is the current and the vertical axis is the current, and the collected data is plotted to obtain an output characteristic curve. This curve is generally referred to as ιν and is a method of using the sunlight as the irradiation light and a method of using the artificial light source as the irradiation light in the above measurement method. In order to use the artificial light source as the light to illuminate, Patent Documents 1, 2 and the like have a method of using a steady light source and a method of using a flash light source. Heretofore, with the practical use of the photoelectric conversion element, in particular, the current-voltage characteristic of a photoelectric conversion element such as a solar cell having a large light-receiving area (hereinafter simply referred to as a solar cell b battery) is one of the standard illumination of sunlight. Measured at a radiance of about 〇〇W/m2. Further, the illuminance at the time of measurement exceeds the portion where the temperature is less than 1000 W/m2, and the compensation calculation is performed by the calculation formula of the illuminance compensation. 4 201146090 In the measurement of the current-voltage characteristics of a large-area solar cell, it is necessary to uniformly illuminate a large-area light-receiving surface with an illumination of about 1000 W/m 2 . Therefore, when an artificial light source is used, for example, a discharge lamp having a large electric power of about several tens of kilowatts per lm2 is required. However, in the case of using such a large-power discharge lamp to generate stable light, it is necessary to stably supply a large amount of electric power. For this reason, equipment of a very large scale will be required, and there is no reality. Further, in a solar simulator using stable light, a xenon or metal halide lamp for continuous lighting is used as a light source lamp. Fig. 10 is a view showing the relationship between the illuminance of the lamps and the time. As shown in the figure, it takes a few ten minutes or more for the lamps to start from lighting to illuminance. Further, if the illumination is not continued under the same conditions, the illuminance does not become saturated, and a considerable amount of time is required until the measurement. On the other hand, if the accumulated lighting time becomes long when the time is long, the illuminance tends to decrease gradually, and the illuminance characteristic is unstable. In addition, the light exposure of the solar cell belonging to the object to be measured is performed by switching the light blocking and the irradiation by the shutter switch, and the irradiation time of the test body is based on the operating speed of the shutter, and the irradiation time is usually 100 msec. the above. If the irradiation time is long, the temperature of the solar cell itself rises, making it difficult to measure with high accuracy. ^ In a solar simulator using stable light, in order to stabilize the illuminance, it is necessary to maintain continuous lighting. However, in the case where the light source is housed, the degree rise will become remarkable. χ, the parts inside the casing are often exposed to light, which is the cause of deterioration of optical parts (mirrors, optical filters). In addition, the light source lamp that stabilizes the light only needs to be turned off once, and then lights up until the illumination reaches a high probability of 201146090. Saturated, it takes tens of minutes for 4 to avoid this problem. It often takes 4 results in the continuous point f(10) state, and the cumulative point is easy to increase in the light-stabilizing lamp. The result is in a short time. In the manufacturing line of the solar module b battery module, if the stable light method is used to display the H, the (four) (four) Lai number is added to the test cost, which is not only the cost, but also the manufacturing cost of the solar cell. Will also improve. Further, in the case of the %, twilight simulator, the light source light is irradiated to the solar cell of the object to be measured for a long period of time. Therefore, if the same solar cell is repeatedly subjected to the measurement of the IV curve, the temperature of the solar cell will rise. It is generally known that if the temperature of the solar cell rises, there is a tendency for the output voltage to decrease, and the maximum output Pmax will also decrease as the temperature rises. Therefore, in the simulator using stabilized light, the temperature of the solar cell is measured in the measurement and the compensation formula for temperature compensation is specified in accordance with the standard. β However, there are problems in the measurement of the temperature of the solar cell as follows, and it is not simple. It is used for solar cells for electric power such as general residences. 2 E VA (ethylene acetate), solar cells are laminated, and EVA is laminated on the surface side glass, and resin X-sided sheets are provided on the back side. The layered structures are stacked. If the solar cell of the f-structure is subjected to temperature measurement on its manufacturing line, the measurement of the solar cell surface or the temperature of the glass surface is measured only by the measurement. Therefore, J7 emits light from the solar simulator to temporarily increase the temperature of the solar cell due to light, and it is quite difficult to accurately measure the solar cell unit itself 201146090/surplus. For this reason, it is difficult to measure the temperature of the solar cell with high accuracy. Therefore, it is also difficult to correctly perform temperature compensation. Here, there is proposed a method of measuring the current confidentiality of a large-area solar cell by generating a flash of unsteady light. In the case of a light source that generates a flash of suspected sunlight, a xenon lamp is used, and a single flash using a longer flash time is used, and a flash using a short flash is used for a plurality of times. test methods. Regardless of the measurement of the current-voltage characteristics of the solar cell in which the flash is utilized, there is almost no problem of solar energy = also rising in the measurement, and there is almost no need for temperature compensation. Further, in the simulator for collecting data by using the flash, since the interval between the f temples is shortened, the deterioration of the optical components such as the above-described stable U solar region (4) can be alleviated, and the lamp life becomes long. However, it is known that when the gas lamp is flashing, the illuminance is scattered and irregular. Therefore, it is necessary to maintain the illuminance within the allowable range of ±5% or so. r: Two light: bright. Further, although the illuminance is compensated according to the illuminance at the time of light emission, the measurement range is relatively large, and the measurement accuracy is relatively deteriorated. Ιν ^ Jiu Qiaozan, the load of the solar cell, gives a characteristic curve that must produce a long pulse of more than 100msec. In order to enter the pulse = light, the light between the light and the light of the next time - is a long time. Therefore, in the first flashing light, if the illuminance adjustment is incomplete due to the unclearness of the illuminance, the next time the illuminating 201146090 waits for a long time. Moreover, since the load for flashing light is large, the life of the light as a light source is shortened. The method of measuring the short flashes in a plurality of times can be made to emit light at short intervals because the load of the flashing light is small. Further, since the lighting time is short, the condition (e.g., 'temperature) inside the lamp does not change and the illuminance is improved. Since the temperature of the solar cell as the object to be measured does not rise, it is not necessary to capture it. South 〃 However, the measurement of the short flash has the following problems. Figure 2 shows a diagram of a short flash waveform. As shown in the figure, the waveform of each of the plurality of illuminations has a mountain shape having no flat portion at the top (the shape of the bottom of the mountain shape is about one: one shape. Therefore, in one flash illumination, only: collection-group ( The illuminance, the output current of the solar cell, and the voltage of the solar cell.

Also fixed. One configuration may be such that the light source lamp 1 is used in a plurality of forms in Fig. 3. The y light source lamp 1 uses a xenon lamp or the like. In order to make the flatness of the upper flat portion of the illuminance waveform into a desired shape, the power supply circuit 2 is configured to include a pulse width towel. Here, since its structure is not directly related to the contents of the present invention, it is omitted. By the action of the power supply circuit 2, as schematically illustrated in the waveform diagram of the figure, the light source lamp can be flashed by the upper flat portion of the control optical pulse waveform at about 0 〇 msec or more. X, the width of the light pulse must be determined in consideration of the characteristics of the solar cell of the object to be measured. For example, in the case of a solar cell having a slow domain characteristic, the flat portion of the pulse waveform shown in Fig. 1 is set to be 100 msec or more and 500 msec or less. In the case of a solar cell with very low responsiveness, it can be adjusted to a maximum of about 5 〇〇 msec. On the other hand, in the case where the response characteristics of the solar cell are fast, the upper flat portion of the pulse waveform shown in Fig. 1 can be made shorter than 100 msec, and even shorter than 4 msec. In the case where the upper flat portion of the pulse waveform is about 100 to 5 〇〇 msec, even if the solar cell is slow to respond, it is not necessary to perform a plurality of flashes of light, and the output measurement can be performed by one-time light illumination. In the above-mentioned aspect, the illuminance of the light source lamp 闪光 of the flashing light is as shown in FIG. 3 14 201146090, and the dance is detected by the illuminance detection 3 of the solar cell opposite to the lamp 1 as the § illuminance detector 3, It is preferable to use a solar cell unit having the same performance as the body to be measured. In the solar simulator of the present invention, the current/voltage output from the solar battery 4 disposed opposite to the source 1 as the object to be measured is variable. To this end, an electronic load is placed at the output terminal of the solar cell 4. Further, the electronic load device is composed of a load circuit, a DC power source, and a barrier temple. The data of the measured illuminance of the current and voltage output by the solar cell 4 and the self-illumination detection $3 are collected by the lean collection system of the solar simulator of the present invention. As the data collection system, as shown in FIG. 3, the data collection board 7 having an electronic circuit formed on the main body is connected to the computer 6 having the data processing board 6a and the analog output board, and the electronic circuit system is constructed. The analog signal is converted into a digital signal and then collected. Further, the electronic load command circuit 8 is connected to the electronic load device 5 in order to transfer the data from the computer 6. <3> Adjustment of Irradiation Illumination A method of adjusting the illuminance of the illumination light irradiated from the light source lamp when measuring the rotation characteristics of the solar cell to be measured is described below. First, the adjustment of the illuminance detector 3 is performed as follows. At the position where the solar battery 4 to be measured is disposed, the reference solar power is disposed instead of the solar battery 4, and the illuminance detector 3 is placed at a predetermined position. The short-circuit electricity of the reference solar cell is set in advance on the data processing board 6a. 15 201146090 The flow isc and the information of the open electric house v〇c. Further, the illuminance detector 3 is also set in advance on the data processing board 6a to set the short-circuit core and the open money v maximum power-deletion. Then make the gas lamp! The light was emitted, and the output of the reference solar cell and the output of the illuminance detector 3 were measured at this time. The illuminance of the gas lamp 1 can be obtained from the output of the :: energy battery, and the illuminance of the gas lamp 1 can be measured by the illuminance detector 3 by detecting the illuminance of the output of the yoke 3 and the xenon lamp 1 in comparison with the current illumination. The data processing board 6a compares the predetermined illuminance (reward w, 、, , degree ′: the illuminance of the heart 3 is compared with the calculation unit of the computer 6 and then controls the analog output board according to the calculation result of the calculation unit. The output 曰 7 is used for 5 weeks of illuminance, and the analog output board 6b controls the applied voltage as the light source and the gas lamp 1. Furthermore, the analog output board 6b has a k-output portion, and the output control is applied to the power supply of FIG. The control signal of the charging voltage of the DC power source in the circuit 2. In this way, the condition that the illuminance of the gas lamp i becomes a predetermined illuminance - 1000 W/m can be automatically obtained (the voltage is applied, and then the measured body is placed as the measured body). The solar cell b battery replaces the reference solar cell and starts the measurement. Furthermore, the adjustment of the illuminance detector 3 can be performed only once, and from the second time, it can be based on, and the target is displayed. 、、、 铋 裔 裔 裔 裔 裔 裔 裔 裔 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑 电脑Can be projected by the illuminance detector 3 and the computer 6 Degree 'has been so far due to manpower operation 16 201146090 and it takes a long time to adjust the illuminance, so that it can be short-term side = again, since the irradiation time does not become longer, it will not be recruited: the temperature of the solar cell of the carcass rises Therefore, it is possible to improve the disadvantages of the conventional method of measuring the change in the characteristics of the solar cell caused by the irradiation time == and the difficulty of determining the accuracy of the South. + One example of the solar simulator of the present invention is as described above. '. With a moderate lamp, the light source will be lit! The flash will light up and the illuminance will be detected by the genre 3. The illuminance measured is via the data slab = calculation and specification in the data processing board 6a Value (10) Eye (5), more calculation. If the detected illuminance is the same as the specified value or the approximate range is called the material), it is difficult to transfer to the solar cell 4 = In the case where the detected illuminance (4) is higher (or) lower than the (4) (4) material side In the middle, the voltage of the lamp is automatically controlled to make the illuminance a standard value* (including the allowable range). Pre-master the illuminance characteristics of the lamp (4), so that the illuminance can be adjusted according to the lamp (4).曰<4> The change of the indication value of the electronic load in the measurement method of the present invention is controlled by the adjustment method of the illumination illuminance of the above <3>, and the control is connected to the solar electric electronic load. The device 5 increases or decreases the output or voltage from the solar cell 4. The command circuit 8 scans the electronic load device 5 with ec = time for changing the command value. In the course of the advancement, according to the response characteristics of the solar cell belonging to the measured body, the method of changing the speed of the electronic negative cutting is performed, and the short-circuit current isc of the solar cell and the open voltage voc. The material of the optimum operating voltage v, is preliminarily provided with the bellows processing plate 6a, and is applied by changing the voltage or current together with time. The dotted line of Fig. 4 changes the voltage or current at a predetermined speed in the case of the conventional measuring method. On the other hand, in the case of the present invention, the electric waste or the current can be freely changed with respect to time. Specifically, it is explained as follows. <5> Example of Measurement Method of the Present Invention ι In the embodiment of the solar cell described below, the response is slow in the vicinity of the current/voltage value (optimal operating point) at which the maximum electric power is displayed (area M in Fig. 9). While in other load areas (area ni and area N2 of Figure 9), the solar cells respond quickly. In this embodiment, the electronic load command is controlled by current. The operating current of the solar cell is operated according to the f-sub-sense, and the voltage value of the solar cell that is subordinate to the object to be measured is measured. Figure 5 (b) shows the pattern & c of the time change of the current command. Fig. 5 (The output characteristic curve obtained by the patterns a, b, and c according to the time of the current command. In (a) and (b) of Fig. 5, the pattern a (dotted line) indicates a certain speed. The current command is used to determine the state of the solar cell. The pattern b (-point chain) is also a conventional measurement method, which means that the solar cell output characteristics are measured by the current command at a certain speed of the vehicle. The pattern c (solid line) is the time of the current command 201146090 in the measurement method of the present invention. In this case, the change is shown in the vicinity of the optimum operating point and the change speed of the pattern a. The speed is used to adjust the current command, according to the characteristics of the positive yoke. In the present invention, == = yang = the characteristic should change the speed of the current command, so the response can be as short as possible. Characteristic curve c (solid line) _ (a) is not correct - the traditional pattern 3 refers to human inflammation according to a certain speed, so s + current command in the solar cell response characteristics: two m order 'for yang battery The current command value is not sufficient == Two times a in the solar cell characteristics, can be obtained in Figure 5 (a):, in order to calculate the line) 'equivalent to the measurement of the original output characteristics ^, H (imaginary design b according to a certain speed The command is to measure the output characteristics in response to the full response of the solar cell. The second is the case where the time of the current command changes. The delay of the shape = the shape of Fig. 6 and the illuminating time (measuring time: and speed: ( Electricity (4) Port t) j is not the pattern & 愔 夕 : 便 便 便 便 便 便 便 便 便 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计 计, available: two (-pointing is equivalent to measuring the original round-off) and then 'the above-mentioned luminous time (measuring time) is increased, due to the illuminating heat of the light source 19 201146090, the solar cell belonging to the measured body The output characteristics are lowered and the measurement with high accuracy cannot be performed. Moreover, the increase of the measurement time will cause the enlargement of the lamp illumination device and the increase in cost. In the measurement method of the present invention, the response is measured in the shortest possible time. Slow solar cells, The problem of the above-described measurement method of the pattern #a and the pattern b is not repeated. <6> Example 2 of the measurement method of the present invention According to Fig. 7, (4) Examples of other aspects of the solar cell are described in τ: In the vicinity of the current/electric dust value (optimum operating point) indicating the maximum power (region Μ in Fig. 9), the response is slow, while in other load regions (region Ν1 and region Ν2 in Fig. 9), the solar cell responds quickly. In the embodiment, the voltage control material is negatively controlled. (4) The electronic load command is used to operate the operation of the solar cell, and the current value of the solar cell outputted by the body is determined. Figure 7 (1) shows the time variation of the electric house command. Patterns b and ? Figure 7 (a) is the output characteristic curve obtained by the time-varying pattern of the voltage command and the c. A (4) and (1) towel of Fig. 7, the pattern a (dotted line) indicates that the point key of the solar cell is measured by a voltage command of 疋t degrees, which is also a conventional measurement method, and indicates that the voltage is slow. Let's measure the condition of the solar cell. Figure 2 (solid line) is the instruction of the method of the present invention. In this case, it is indicated that the voltage command output characteristics are adjusted in the same measurement time as the pattern a, in the optimum operation, _ near, (four) sample " change speed and the change speed between _5 and 20 201146090. In the present invention, the response characteristic of the energy-receiving battery of the solar battery is used to change the speed of the voltage command: the solar battery can obtain the output characteristic curve C (solid line) as shown in Fig. 5 (4) in the shortest possible time. /, the conventional pattern a according to a certain speed command to change the voltage to the voltage command is faster than the solar cell response characteristics (four) = $ yang battery due to the voltage command value is not fully underground, in order to measure the characteristics of the solar cell, can be obtained Figure 7u The two-dimensional curve & (dashed line) corresponds to the measurement of the original output characteristics: The conventional pattern b is based on a constant speed command, which is determined by the fact that the solar cell is fully responsive and the time of the second round of the measurement is changed. Even in this kind of measurement of the output characteristics of the solar cell, the solar cell is not fully fully responsive in response to the power = command value: therefore, the output characteristic curve b of Figure 7 (a) can be obtained (- The point chain line) is measured inside the original output characteristic. Again, this situation and the embodiment! In the same manner, the light-emitting time (measurement time) is increased by the light-emitting heat of the light source lamp, and the output characteristics of the solar cell belonging to the object to be measured are lowered, so that high-accuracy measurement cannot be performed. In addition, the increase of the count = increases the size of the hairline and the county. In the measurement method of the present invention, since the solar cell having a slow response is measured in the shortest possible time, the above-described problems of the measurement method using the pattern a and the pattern b 21 201146090 are not repeated. <7> Example 3 of the measuring method of the present invention In the case of using a light source having a short light-emitting time, as shown in Fig. 8, the flash is divided into a plurality of times to perform measurement, such as a solar cell having a slow response characteristic. The output characteristics are in accordance with the embodiment! Conventional measurement method: When the point chain line b changes the current with time, it can be divided into a defect point corresponding to the vein A portion of Fig. 8 (a) and a measurement point corresponding to the B material. The measurement of the measurement method of the portion A of Fig. 8 (a) is carried out by the measurement method of the present invention by the light emission of Fig. 8 (1). Further, the measurement of the measurement point of Fig. 8 (1) was carried out by the second measurement method of the light emission of Fig. 8 (1). According to the measuring method of the present invention, the load command speed is appropriately adjusted as shown in FIGS. 5(1) and 7(b), and a low-lying lamp light-emitting device can be used without causing the output characteristics of the solar cell: In the fourth embodiment, a solar cell having a high accuracy in a short period of time is obtained. <8> The response characteristic of the solar cell is determined by the type of each solar cell, even if it is the same type of solar cell. There are also differences. The solar energy characteristic = difference is the optimum operating point position of the response characteristic. The area where the optimum operating point is dispersed is set to the area Ν. The area Ν is set to the area N1 and the area Ν2. The change of the electronic load indication value in the area # this clock and the milk will be patterned. Fig. 9 shows the setting of the pattern. In this figure, there are three types of 22 solar energy modules A, B, and C that are roughly distributed. The action point is set to the area of the electronic load indication value, and the load change speed is set according to the response speed of the solar cell module. In addition, the area Ν1 and the target I丨α π fly Mi and Ν2 accelerate the electronic load. In this case, the solar cell of the (fourth) type is set to have a change rate of the electronic load: a more pattern, and the solar cell of the portion of the slow response portion can be measured by the same change pattern. Output special = and a variety of types of solar energy with slow response characteristics on the production line: When measuring the output characteristics of the pool, it is easy to adapt to the model change by setting the k-pattern of the change speed of the electronic load.
