Abstract
The utility model relates to a thin -film solar cell nature ageing tests device, include: pneumatic membrane structure as the backplate, be filled with gas in the pneumatic membrane structure, tan by the sun on the surface that thin -film solar cell is fixed in pneumatic membrane structure to simulation thin -film solar cell's self aging. The utility model provides a technical scheme is filled with gaseous pneumatic membrane structure conduct through inside and tans by the sun the backplate, and tan by the sun on the surface of being fixed in thin -film solar cell pneumatic membrane structure, because pneumatic membrane structure makes pneumatic membrane structure's the temperature and the stress of tensile production change in the illumination difference that daytime and night received. Because in the in -service use, thin -film solar cell fixes when the dirigible surface, is filled with the helium in the dirigible, in the illumination difference that daytime and night received owing to the dirigible, messenger's dirigible hull temperature and tensile stress are changing, consequently the utility model provides a technical scheme can simulate the self aging of solar cell when dirigible hull surface more really.
Description
Technical field
This utility model relates to material natural aging field, particularly to a kind of thin film solar electricity
Pond natural ageing test apparatus.
Background technology
In recent years, thin film solar cell technologies is developed rapidly.Existing stratospheric airship is equal
Using thin-film solar cells to provide the energy, the development target of stratospheric airship is by for a long time
Flight in sky, the performance of thin-film solar cells directly affects the flight time of dirigible.Thin film is too
Sun can battery be a kind of multi-layer compound structure, be the most inevitably exposed to or
Connect is exposed in natural environment, in the comprehensive function by factors such as light, heat, oxygen, water,
Its performance constantly deteriorates, and service life is gradually shortened.Must take into thin-film solar cells from
So ageing properties.Correlational study is mainly entered by the method for natural solarization or laboratory accelerated ageing
OK.At present, national and foreign standards tissue has all worked out natural atmosphere exposure and artificial accelerated aging is surveyed
The relevant criterion of method for testing, to investigate the aging of thin-film solar cells monomer and assembly.
Natural aging is by directly utilizing the factors such as light in natural environment, water, temperature to sample
Effect and study and record various material character result of variations, owing to its experimental condition is real
Reflect the partial condition in test specimen practical service environment, so natural ageing test result and reality
Between the result that border produces in using, concordance is good, dependency is good.This test oneself be recognized and be
Examine the most important of all kinds of macromolecular material environmental suitability and reliability, be also to use the earliest
, the most real method, the method being also used extensively by now.
Currently, the natural aging for thin-film solar cells typically uses and tans by the sun without backboard or carry on the back
Plate tans by the sun method.Tan by the sun without backboard and refer to clamp or hitch material end, make major part material expose
Shine in surrounding air；Backboard tans by the sun the paper referring to be installed to by sample on underbed or bracket
On clamping plate, the actually used situation having backboard or supporter of simulation material.Test specimen uses a scale
Very little monomer test specimen or assembly test specimen.
Stratospheric airship, when actually used thin-film solar cells, fills helium in stratospheric airship
Gas, helium specific heat capacity is less, sensitive to variations in temperature.Sun direct projection on daytime, in causing hull
Portion's gas temperature raises, and one is to cause Thinfilm solar cell assembly backboard temperature to raise；Two are
Cause hull volume to increase, and then Thinfilm solar cell assembly is stretched by hull structure
The stress produced.At night, ambient temperature decline causes internal air temperature to reduce, and one is to cause
Thinfilm solar cell assembly backboard temperature reduces；Two is to cause hull volume-diminished, and then makes
Obtain Thinfilm solar cell assembly and produce deep camber fold with hull.So, day-night cycle
Thinfilm solar cell assembly will produce the alternate load of temperature and stress, this load is bound to shadow
Ring Thinfilm solar cell assembly natural aging performance in actual use.And current thin film
The flat back plate light exposure test of solar battery cell natural ageing test and assembly cannot be anti-
Reflect the effect of above-mentioned alternate load.
Furthermore, in true use, Thinfilm solar cell assembly is layed in stratospheric airship hull
Back, because stratospheric airship is fusiform body of revolution, the bending at hull back, one is to cause
The structural bending of Thinfilm solar cell assembly；Two is the thin film causing being in hull different parts
Angle of radiation suffered by solar module is different, and the corresponding different radiation of different angle of radiation is strong
Degree, and then the duty that corresponding Thinfilm solar cell assembly is different.Both affects thin film
Solar module natural aging performance in actual use.And the plane of current assembly
Backboard light exposure test cannot reflect the impact of curvature.
So, need badly at present a kind of can either temperature suffered by simulation thin film solar module
And two kinds of alternate loads of hull structure tension and compression stress, hull structure can be simulated again and bend thin
The device of film solar cell natural aging impact.
