Due to the adoption of the temperature sensor, the absolute illumination intensity values of all independent points can be obtained, therefore, the problem that the traditional multipoint test method can not test the absolute illumination intensity is solved, and through the comparison between the absolute illumination intensity and the standard illumination intensity, the performances of the solar simulator can be analyzed more effectively.
Description
Technical field
The utility model relates to a kind of solar simulator irradiation uniformity coefficient proving installation.
Background technology
The sun power industry development is swift and violent in recent years, and various solar simulators are also more and more, and are also more and more higher to the performance requirement of simulator each side, and wherein solar simulator radiation uniformity coefficient is exactly crucial performance index.At present in field of solar energy, the test of paired pulses solar simulator light uniformity coefficient, mainly be multiple spot to be tested then one by one calculate, but because the repeatability of the simulator property of there are differences within the specific limits itself, Shan Guang good fortune illumination all is differentiated in fact each time, and it also is inaccurate so the value of measuring in this way being compared.
Three, utility model content
The utility model is at the above-mentioned technological deficiency that prior art exists, and a kind of simple and easy, low-cost, the radiation uniformity coefficient that can measure solar simulator simultaneously that testing efficiency is high and the absolute pulse solar simulator irradiation uniformity coefficient proving installation of light intensity are provided.
The utility model main design thought is: adopt multiple spot once to test, once finish data acquisition, make test result more accurate.In addition, the temperature during owing to test is unfixed, so traditional multi-point sampler has no idea to obtain the numerical value of absolute light intensity; The utility model has used temperature sensor, can calculate according to the temperature coefficient of solar cell, obtains the absolute illumination intensity value of each test point in the testing radiation uniformity coefficient, more helps passing judgment on the performance of simulator.
Technical solution of the present utility model is:
A kind of solar simulator irradiation uniformity coefficient proving installation, comprise temperature sensor, a plurality of solar cell, with a plurality of sample resistances, a plurality of analog-digital converter, multichannel data processor, the computer of each battery coupling.The corresponding sample resistance of each solar cell, each solar cell is in parallel with corresponding sample resistance, and described sample resistance is set unified resistance value; Sample resistance is connected with analog-digital converter, the corresponding analog-digital converter of each sample resistance, and each analog-digital converter all is connected with the multichannel data processor, and the multichannel data processor links to each other with computer respectively with temperature sensor.
Principle of work is: when a branch of illumination is mapped on the solar cell, solar cell changes into corresponding electric energy with luminous energy, external output current, the sample resistance in parallel with solar cell converts current signal to voltage signal, analog-digital converter becomes digital signal with the voltage signal that sends from analog signal conversion, signal sends the multiple signals processor subsequently to, and the multiple signals processor sends to computer with treated signal; Simultaneously, temperature sensor sends the Temperature numerical of record to computer.Computer is with the absolute light intensity of the digital signal of gathering and the temperature value light by calculating each solar cell position and the irradiation uniformity coefficient of solar simulator.
The utility model is with respect to its beneficial effect of prior art:
(1) the utility model is simple in structure, with low cost, uses efficient and convenient.Once finish test, avoided repeatedly measuring the shortcoming of bringing that error is big, testing efficiency is low, an illumination just can be finished test, both has been applicable to the pulsed solar simulator, also can be used for the stable state solar simulator.
(2) behind the serviceability temperature sensor, can obtain the absolute illumination intensity value of independent each point, solve traditional multi-point sampler and can't test the problem of absolute light intensity, by the diversity ratio between absolute light intensity and the etalon optical power, can analyze the performance of solar simulator more effectively.
