2.In the present embodiment, this light source 16 continues to open with this determinand 14 of prolonged exposure.
In the present embodiment, this light source 16 is the light source of simulated solar irradiation, and the light intensity of this light 17 is general sunlight (1000W/m
2) 2.4 times to 3.5 times.Namely, the light intensity of this light 17 is 2400W/m
2to 3500W/m
2, make the light intensity suffered by upper surface 141 of this determinand 14 be 2400W/m
2to 3500W/m
2.
Preferably, the heterogeneity of this light intensity suffered by determinand 14 is less than 5% (defining according to the measurement mode about heterogeneity (non-uniformity) in IEC60904-9).The spectral range of this light source 16 is 200nm to 1300nm.Whereby, the condition of this determinand 14 when sunshine can be simulated, and strengthen intensity of sunshine to 2.4-3.5 times, and improve the temperature that this determinand 14 is produced under light illumination, make the temperature that the temperature of this determinand 14 produces higher than irradiation under physical environment, to accelerate this determinand 14 because of the destruction that occurs sunshine or the reaction that decays.
With this understanding, this determinand 14 heats up because of illumination.Now, the temperature in this accommodation space 10 and humid control in a preset range (such as: temperature controls in the scope of-40 DEG C to 90 DEG C, and humid control is in the scope of 20% to 95%).Be understandable that, this temperature and this humidity are the environment that may to run into future according to this determinand 14 and set its scope.
Then, provide a heat abstractor 3 to reduce the temperature of this determinand 14.Namely, control the temperature of this determinand 14 (such as: between 45 DEG C to 75 DEG C) in a preset range, can effectively suppress the persistently overheating of this determinand 14, directly cause artificial damage but not corollary failure because of temperature overheating (such as: more than 90 DEG C) to avoid this determinand 14.In the present embodiment, be utilize this temperature and humidity control device 20 to control temperature in this accommodation space 10 and humidity, and utilize this heat abstractor 3 to control the temperature of this determinand 14 in above-mentioned thermal convection mode.

The simulation mechanism of the present embodiment is the destruction utilizing the every formation of energy to this determinand 14 of this light source 16 medium ultraviolet light (200nm-400nm), compound interface carries out chemical bond, is the initiation factor destroyed or decay.In addition, in this light source 16, the part of visible ray and infrared light can cause different materials to absorb heat different effects, and the thermal effect caused can accelerate the speed of material damage, is the speedup factor destroyed or decay.
According to the law of chemical reaction rate, if when irradiation, the temperature of this determinand 14 itself will with the relation of the speed exponentially destroyed, the 2.4-3.5 therefore utilizing light intensity to be sunshine analog light source doubly and control this determinand 14 temperature in can reach the object of quick aging.In principle, illuminance is higher, more effectively can shorten digestion time, and the temperature of this determinand 14 is higher, and the effect of accelerated deterioration can be better.But the temperature of this determinand 14 can not unconfinedly increase, if because this determinand 14 is solar module, it is except cell piece itself, also has some macromolecular materials.This macromolecular material at too high a temperature, can produce direct destruction, and make test crash, is artificial damage but not corollary failure because destroying for this reason.Therefore, the temperature of this determinand 14 can not exceed the endurable scope of its material.Therefore, use the present invention's can simulate this determinand 14 in 3 months aging effect of more than 10 years out of doors, even can simulate the aging effect of 25 years in 1.5 months.
Another embodiment that the present invention accelerates the aging method of determinand is as described below.The present embodiment is roughly similar to a upper embodiment, and it does not exist together and is only the adjustment of light application time.In the present embodiment, after a first period continues to provide this light 17, this light source 16 is closed, to simulate the situation that this determinand 14 has sunshine by day.Then, continue to open this light source 16 again after stopping provides this light 17 in a second phase, to simulate this determinand 14 situation without sunshine at night, and the temperature (such as :-40 DEG C to 20 DEG C) reduced in this second phase in this accommodation space 10 and the humidity improved in this accommodation space 10.Be understandable that, this first period and this second phase are the environment that may to run into future according to this determinand 14 and set its scope.So, repeatedly sequentially carry out above-mentioned two steps, namely, this first period and this second phase hocket.Whereby, the present embodiment can simulate the environmental change of outdoor actual alternation of day and night.This present embodiment utilizes the change of light and temperature produce stress to allow this determinand 14 inside; by the temperature variation higher than normal open-air conditions, and the mode conversion in the short time accelerates the stress impact of this determinand 14 inside to accelerate the aging speed of this determinand 14.
In addition, if this determinand 14 is solar module, the present invention is because the spectrum of this light source 16 and sunshine are similar to, have good uniformity, this determinand 14 can be connected load generating, rush of current can be done to this determinand 14 inside by generating and the flowing of electric current simultaneously, accelerate this determinand 14 inside because of long-term current flowing and cause the passing of ion and the effect of Impurity Diffusion, and then accelerated deterioration effect.
In the present embodiment, the light intensity due to this light source 16 is 2.4-3.5 times of sunshine, and therefore the generated energy of this determinand 14 is also 2.4-3.5 times of normal power generation amount.This 2.4-3.5 current density doubly still can not destroy the structure of the silicon materials of this solar module, and the material attenuate produced is only linearly increase 2.4-3.5 doubly.Therefore, under identical temperature conditions, the generated output decay of many times of illumination generations is linear acceleration.In addition, known chemical reaction rate often increases by 10 DEG C, about fast 2 times of speed.Therefore, under equal illumination, the power attenuation speed of this solar module often increases by 10 DEG C, rate of decay increase about 2 times.Therefore, the present invention utilizes many times of illumination and improves temperature, can accelerate the aging of this solar module.
But above-described embodiment is only and principle of the present invention and effect thereof is described, and is not used to limit the present invention.Therefore, those skilled in the art modify to above-described embodiment and change still not de-spirit of the present invention.Interest field of the present invention should listed by appending claims.
