Background technology:
In recent years, solar cell is as a kind of novel energy of clean environment firendly, obtain application more and more widely, be the key technical indexes of weighing the battery quality serviceable life of solar cell, and be to weigh by the damping capacity of solar cell the serviceable life of solar cell.At present, people adopt open-air formula illumination method of testing that it is tested usually, the battery sheet directly is placed in outdoor, utilizes the sunshine of nature that solar cell is shone, relatively check and rate its damping capacity by the watt level that solar cell to be detected was exported according to the period before and after shining.This open-air formula illumination method of testing; the natural light that solar cell received is very unstable; intensity of illumination, light application time all change with natural weather; people are uncontrollable; not only test period long, and the test data of gained can't repeat, confidence level is poor; the battery sheet is placed in the outdoor protection that also can not get simultaneously, is blown over by the wind easily and breaks.In the manufacture of solar cells industry, though it is to weigh its fine or not the key technical indexes that people know the serviceable life of solar cell, but owing to lack concrete testing standard, the checkout equipment that does not more have public letter, because the user extremely values this index, manufacturing enterprise only promises to undertake to the user can reach 20 years its serviceable life, but does not have corresponding test data to prove.
In order to satisfy user's requirement better, the applicant has formulated corresponding test standard, and has developed a kind of solar cell testing apparatus in serviceable life, with solar battery sheet to be detected particular light intensity (1kW/m
2) analog light source shine, the decay index of solar cell is extrapolated in (60h) illumination decay through after a while under specified temp (25 ℃) environmental baseline, and measure initiating terminal and the open-circuit voltage and the short-circuit current parameter of the end of ending thus.Adopt this analog light source irradiation method of testing, whole die-away test is as long as carry out indoor, intensity of illumination is stable, test ambient temperature, attenuation test time are all controlled, not only test efficiency height, and gained test data good reproducibility, with a high credibility, simultaneously, the battery sheet can not damage in test process.In this solar cell testing apparatus in serviceable life, simulation light source device, exposing frame for use in all are key devices.
Summary of the invention:
The purpose of this invention is to provide a kind of simulation light source device for solar battery attenuation test.
A kind of simulation light source device for solar battery attenuation test, comprise lamp box, simulated solar lamp, temperature sensor, irradiatometer, refrigeration compressor, cooling tube and electric-control board, the simulated solar lamp is distributed on the bottom surface of lamp box, temperature sensor and irradiatometer are fixed on the medial surface of lamp box, electric-control board is installed on the lateral surface of lamp box, refrigeration compressor is installed in outside the lamp box, cooling tube is distributed on the medial surface of lamp box, refrigeration compressor is controlled by temperature sensor, the simulated solar lamp is controlled by irradiatometer, and the intensity of illumination of simulated solar lamp is 0.5～2.0kW/m
