Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
End face in the constant temperature test box 1 is evenly equipped with four continuously adjustable xenon long-arc lamps 2 of power and makes up the simulated solar radiant.Every xenon long-arc lamp range of adjustment is: 0-1500 watt.Because the power of light source can be regulated continuously, the irradiance test condition that we can obtain wanting, the response characteristic of testing solar battery chip under the various conditions or assembly.Irradiance is adjustable from 0.2sun to 1.0sun.
The irradiance of light source is by placing the irradiance meter 3 in the test box 1 to survey, and its data are carried out data processing by the multi-channel data acquisition device.The irradiance probe has one-level probe and secondary probe, when precision measurement, considers to adopt the one-level probe, when common test, considers to adopt the secondary probe.Present embodiment adopts the product of Italian DeltaOHM company, the sensitivity parameter that provides above according to probe:
Internal resistance: 36.2 ohm;
Sensitivity: 14.56uV/ (W/m
2);
Field range: 2 π sr;
Spectral range: 305nm-2800nm (50%);
335nm-2200nm(95％)；
Operating temperature range :-40 ℃-80 ℃;
Weight: 0.45Kg;
We have made an enlargement factor is 68.68 low drift low noise amplifier, and its output response is: the 1sun/l volt.
Temperature and humidity in the constant temperature test box 1 is surveyed by temperature sensor 6 that places constant temperature test box sidewall and humidity sensor 7, and its data are carried out data processing by the multi-channel data acquisition device.
Multi-channel data acquisition device 8: can select suitable multi-channel data acquisition device according to user's oneself needs, as the product of KEITHLEY, GRAPHTEC or other company.Our system has adopted the GL-800 of GRAPHTEC company, and it is the automatic data acquisition device of one 20 passage.20 test channel for this equipment have two basic test channel: one is used for the test environment temperature, and another is used for the irradiance of testing light source.Outside these two basic passages, keep two channel standbies, if needed, can test other parameter (as humidity etc.).For remaining 16 test channel, we are divided into 8 groups to them; Every group comprises two test channel, is used for testing a solar battery chip or assembly, and one of them passage is used for test voltage, and another passage is surveyed electric current.
The multi-channel data acquisition device can connect computing machine or carry out data acquisition with addition of USB storage merely by netting twine, and the fastest sampling time is 100 milliseconds.The USB storage of an external 8G with the fastest sample rate work, was 1 year writing time.Tested object is: voltage, temperature (using the Pt100 thermal resistance), humidity (using the B-530 humidity sensor to do 0 volt to 1 volt ratio conversion of voltage).
Current measurement in the I-V test:, current signal must be converted to suitable voltage signal and carry out data acquisition because the automatic data acquisition device that we use can only be gathered voltage signal.For this reason, we have designed current sampler 9 and have finished this work, and current sampler is made up of sampling resistor and low drift low noise amplifier.We have made four current samplers according to the difference of measurement range, and the range of current that can survey is respectively: 1mA/1 volt, 10mA/1 volt, 0.1A/1 volt and 1A/1 volt.Our range of current that can survey has satisfied the testing requirement of different solar battery chips from 0.1mA to 10A like this.
I-V test is adopted and is decided voltage operation mode, the selecting for use of adjustable electronic load 10: according to the watt level of test chip, should select for use different adjustable electronic loads to measure.In our system, adopted the adjustable electronic load of a 120W.For the test of powerful solar battery chip, can select powerful adjustable electronic load for use, as 200W, 250W, 300W, 500W etc.
For each solar battery chip or assembly two test signals are arranged, correspond respectively to the voltage and current signal of tested solar chip or assembly.They are sent in the GL-800 automatic data acquisition device with temperature signal and irradiance signal and handle.
The subsequent treatment of test data: we can utilize the proprietary data converse routine to convert it data file of EXCEL form to very easily by the I-V performance data that GL-800 automatic data acquisition device measures, and then can obtain the I-V curve very easily.The P-V curve be can obtain from the I-V curve, and then all characteristic parameters: Voc, Isc, Vm, Im, Pm, FF, η obtained.
