The specific embodiment
Fig. 1 roughly represents the structure of an embodiment of solar simulator of the present invention, and Fig. 2 roughly represents the structure of this irradiation light amount control device part, and Fig. 3 amplifies a part of Fig. 2 to represent.
In Fig. 1, 10 representation cases are as the light source consisting of xenon discharge lamp etc., 11 represent to be configured in the rear of light source 10 and the light source reflector for example with oval or parabolic shaft section around, 12 represent by incident from the direct light of light source 10 and the reverberation of light source reflector 11, the 1st plane mirror by it to for example aluminum of substantially vertical direction reflection, 13 represent by incident the catoptrical mechanicalness dim light filter from the 1st plane mirror 12, 14 represent by the light diffusion element of the ejaculation light of incident mechanicalness dim light filter 13, 15 represent by the integrator element of the ejaculation light of incident light diffused component 14, 16 represent by the ejaculation light of incident integrator element 15, the 2nd plane mirror by it to for example aluminum of substantially vertical direction reflection, 17 represent by incident the reverberation from the 2nd plane mirror 16, this light is transformed to the collimation lens of directional light, 18 represent by the ejaculation light of incident collimation lens 17 for example as the shadow surface on solar battery cell surface.
As shown in Figures 2 and 3, mechanicalness dim light filter 13, light diffusion element 14 and integrator element 15 form irradiation light amount control device of the present invention.
Mechanicalness dim light filter 13 is the shadow shields with a plurality of little opening (through hole 13b) of light quantity adjustment use, by spatially adjusting the area of light transmission, the absolute magnitude of the light of ejaculation is changed.This mechanicalness dim light filter 13 consists of the punched holes type dim light filter that is provided with a plurality of through hole 13b on shadow shield 13a in the present embodiment.More particularly, to use be with the staggered structure of outputing a plurality of circular holes in length and breadth for 90mm * 70mm, thickness on the corrosion resistant plate of 1～2mm left and right or aluminium sheet for this punched holes type dim light filter.Particularly use part (non-peristome) structure at random as far as possible that light is blocked.In the present embodiment, particularly, use the punch metal of 60 ° of staggered tool light extinction rates likely of the パ of Co., Ltd. Application チ Application グ セ Application タ ー (punting-center).The mode that it is 60 ° that these 60 ° of staggered punch metals be take 3 angles that line was become that link in the heart in 3 adjacent round through holes is arranged in staggered.
Integrator element 15 is integrator optical systems of fly's-eye lens (fly-eye lens) formula, is known optical element in this technical field.This integrator optical system is configured to, and makes many light sources of being generated by a plurality of lens overlapping as staggered positions, thereby form uniform light, distributes.
Light diffusion element 14 is the elements with original light diffusion function (being also optical attenuation function) and high order diffraction light break-in facility.That is, the optics frequency band shut-off feature possessing by this light diffusion element 14, can block the high order diffraction light component in the spatial frequency distribution that the incident light from mechanicalness dim light filter 13 has, and only makes low-frequency component see through.In addition, being configured to, is not only the diffusion of light, also has the circular diffusion property of having applied refraction, can adjust the decay of light and have approximately 96% high permeability with larger dynamic range.
If each opening footpath of mechanicalness dim light filter 13 is less than the diameter of each lens of integrator element 15, near the edge part of the opening of mechanicalness dim light filter 13, there is diffraction light phenomenon, separated and the dispersion of light occurs on spectrum from the white light of light source thus.In the situation that light diffusion element 14 is not set, the spectral component by this diffraction dissociation is by the fly's-eye lens incident to integrator element 15 with different angles of each spectrum.In fly's-eye lens, the light of guided wave repeats total reflection and is guided to penetrating direction, if but the angle to fly's-eye lens incident is mutually different by the difference of light wavelength, from fly's-eye lens, the angle out time can be different, can not form parallel light, and chromatic aberration occurs.Because chromatic aberration becomes nonparallel light, from integrator element 15, penetrate like this, it is not corrected for directional light in collimation lens 17 yet, and result, can not irradiate the spectrum that is similar to sunshine.
With respect to this, as in the present embodiment, by the light diffusion element 14 that not only light is spread, also brought into play as high order diffraction light cut filter function is set between mechanicalness dim light filter 13 and integrator element 15, the chromatic aberration that near the high order diffraction light occurring the edge part of the opening by mechanicalness dim light filter 13 can be produced is removed.That is, by making light diffusion element 14 there is the function of topics such as spatial frequency filtering device, high order diffraction light is removed, can not caused spectrum change and stably keep the uniformity and the depth of parallelism.
In addition, the size of the light diffusion element 14 of present embodiment is according to the size of the size of solar simulator and integrator element 15 and difference, but is for example about 60mm * about 60mm in length and breadth, and thickness is about 3mm left and right.In addition, this light diffusion element 14 is quartz plate low angle light diffused components, for example, can obtain as the Light Shaping Diffuser of the High Temperature Quartz Substrate SOLGEL Type of U.S. Luminit company.
This light diffusion element 14, owing to having the function as topics such as spatial frequency filtering device that high order diffraction light is blocked or reduce, also has by refraction and waits the function that makes light diffusion, so penetrate in light and can not follow diffraction phenomena at it, spectrum does not occur and disperse.In addition, light diffusion element 14 preferably can make light (coherent light and incoherent light) in the scope of approximately 10～30 °, spread in half spectrum amplitude, more preferably can in the scope of 10～20 °, spread.If half spectrum amplitude is narrower, can not make the chromatic aberration homogenising that produced by high order diffraction light, in the situation that wanting to make light dim light to floor level, likely can not eliminate the chromatic aberration being produced by high order diffraction light.In addition, this light diffusion element 14 preferably can form the ejaculation light of the Gaussian distribution with approximate desired.And then light diffusion element 14 preferably disposes the tectosome of countless relief patterns randomly, by thering is random characteristic, also there is the effect that the diffraction light of high-order is cancelled out each other.In addition, this light diffusion element 14 preferably bear hot ability strong, can at the temperature of 500 ℃ of left and right, move.
Light diffusion element 14 can move by not shown axial moving mechanism on optical axis direction, thus, and can be by the distance d between light diffusion element 14 and integrator element 15
1variable control.In the case, the position of mechanicalness dim light filter 13 and integrator element 15 is fixed.By making, apart from d1 variation, (this also makes the distance d of mechanicalness dim light filter 13 and light diffusion element 14
2change), to the light quantity minor variations of integrator element 15 incidents, result, can carry out the fine setting of light extinction rate.
The actual distance d that makes 15 of light diffusion element 14 and integrator elements
1change, measured the illumination of shadow surface 18.The apparatus structure example that Fig. 4 explanation is used in this experiment.As shown in the drawing, in the light source side of light diffusion element 14, do not configure mechanicalness dim light filter, be provided with wavelength conversion filter 21.This experiment is to confirm that light extinction rate is with respect to apart from d
1relation, so mechanicalness dim light filter omits.In addition, between integrator element 15 and light diffusion element 14, dispose shutter 22.
First, make light diffusion element 14 with respect to the distance d of integrator element 15
1for d
1=29mm, measures light extinction rate, obtains 35%.Light diffusion element 14 is moved and make light diffusion element 14 ' with respect to the distance d of integrator element 15
1for d
1=40mm, measures light extinction rate, obtains 40%.
Therefore known, if make light diffusion element 14 near integrator element 15, light extinction rate diminishes, if away from integrator element 15, it is large that light extinction rate becomes.That is, if apart from d
1change about 10mm, light extinction rate changes 5%.
Collimation lens 17 be for incident light is carried out alignment at the known optical element of this technical field.
The action of the solar simulator of present embodiment then, is described.
From the light of light source 10 radiation, directly or by light source reflector 11 reflect again by the 1st plane mirror 12 reflections and to mechanicalness dim light filter 13 incidents of irradiating light amount control device.Incide light in mechanicalness dim light filter 13 by seeing through a plurality of less through hole 13b, its part is truncated and by dim light, to light diffusion element 14 incidents.The ejaculation light of mechanicalness dim light filter 13, by these light diffusion element 14 diffusions, carries out equably dim light on its full spectral domain.And then, even there is diffraction light phenomenon near the edge part of the through hole 13b of mechanicalness dim light filter 13, also owing to carrying out blocking of high order diffraction light in this light diffusion element 14, so penetrate in light chromatic aberration does not occur at it.The ejaculation light of light diffusion element 14 is to 15 incidents of integrator element, by its fly's-eye lens, many light sources are next overlapping as staggered positions, thereby form uniform light, distributes.In the face forming like this, the light of even and uniform spatial distribution is after by the 2nd plane mirror 16 reflections, is transformed to completely after directional light in collimation lens 17, is irradiated to the shadow surface 18 as solar battery cell surface.
Fig. 5 explanation is as the general movement concept of 1 lens of the integrator element 15 of fly's-eye lens.
In uniform irradiation optical system, maximum object is the light beam of light source 10 (luminous flux) to be taken out to greatest extent and the picture of light source 10 (for example picture of lamp electrode) is removed, and therefore conventionally uses light source reflector 11 and the integrator element 15 with oval or parabolic shaft section.In the situation that do not use integrator element 15, will only by the light beam after light source reflector 11 optically focused, utilize collimation lens 17 to be transformed to collimated light beam and irradiate, on shadow surface, occurring the picture of lamp electrode.Thereby, for such picture is removed, need to use integrator element 15.In order effectively to use such integrator element 15, with respect to the incidence angle θ from light source reflector 11
iN, make angle of emergence θ
oUTfor same angle, not only can suppress thus the light loss of integrator element 15 inside, can also carry out the design of integrator element 15, not form picture by making the picture of lamp electrode be imaged on the inside of integrator element 15 at emitting side.
In Fig. 5, if establish O
1for the centre of sphere of the light incident side sphere 15a of 1 lens of integrator element 15, establish O
2for the centre of sphere of emitting side sphere 15b, the focal length f of light incident side
1for f
1=O
1* 2, the focal length f of emitting side
2for O
2* 2.According to the 1/a+1/b=1/f of the formula as lens, in the situation that the object distance of emitting side is a<f (shorter than focal length), the image distance of emitting side is b (-), so penetrate light at outgoing plane 15b optically focused not, and be diffused ejaculation, will never optically focused.
Fig. 6 explanation is in the situation that be inserted in mechanicalness dim light filter 13 nearby the effect of the integrator element 15 of (light source side) in the solar simulator of present embodiment.
In the situation of light source 10 sides of the integrator element 15 designing under these conditions, the mechanicalness dim light filter 13 that the dim light of take is formed by punched holes type dim light filter as object disposes, at integrator element 15 nearby, as 2 secondary light sources, produce the picture of the through hole 13b of mechanicalness dim light filter 13.
In the case, as shown in Figure 6, according to the rule of refraction, the incidence angle θ that P is ordered
iNfor θ
iN=θ
1+ α, incident in the medium from P point from air to refractive index N1, so its refraction angle is θ
1-γ.On the other hand, the incidence angle θ of outgoing plane 15b
2+ γ represents, from the refraction angle θ of outgoing plane 15b
2+ β represents.In the case, angle from from the picture of the through hole 13b of mechanicalness dim light filter 13 to 15 incidents of integrator element is varied, in the situation that incidence angle is larger, inciding the light that P orders is refracted the medium refraction (from air to quartz) of rate N1 and is not imaged onto optical axis, and be imaged onto on outgoing plane 15b, refraction (from quartz to air) again, imaging outside outgoing plane 15b.This phenomenon is according to optical profile type 1/a+1/b=1/f, thinks that the in the situation that object distance being ∞ or 0,1/b=1/f sets up on outgoing plane 15b, thereby the image distance of outgoing plane side is (+), in the imaging of the right side of outgoing plane 15b.
In order to confirm this phenomenon, carried out following experiment.

Measurement result while representing not insert the non-dim light of mechanicalness dim light filter 13 and light diffusion element 14 in Fig. 8.When non-dim light (1SUN), in position, 1,5 and 16 have all obtained roughly the same spectral intensity distribution.Measurement result while on the other hand, representing to have inserted the dim light of the mechanicalness dim light filter 13 being formed by punched holes type dim light filter in Fig. 9.When this dim light, with respect to the spectral intensity of the position 1 of non-dim light (1SUN), distribute, the 5 and 16 spectral intensities distributions that change for certain degree in position.With respect to this, the measurement result while representing to have inserted the dim light of the mechanicalness dim light filter 13 being formed by punched holes type dim light filter and the light diffusion element 14 being formed by quartzy light diffusion element in Figure 10.Even during dim light, by inserting light diffusion element 14, the spectral intensity that position 5 and 16 spectral intensity distribute also for the position 1 with non-dim light (1SUN) the approximate characteristic that distributes, by the light diffusion element 14 that insertion is formed by quartzy light diffusion element below at mechanicalness dim light filter 13, spectral intensity distributes and is significantly improved, and in each position, mutually changes hardly.
In addition, about the consistent degree of spectrum also as shown in figure 11, obtained same result.In addition, in Figure 11, transverse axis represents wavelength (nm), and the longitudinal axis represents that spectrum unanimously spends.According to JIS standard, the higher limit of the consistent degree of spectrum is set to 1.25, and lower limit is set to 0.75.When not inserting the non-dim light of mechanicalness dim light filter 13 and light diffusion element 14 (1SUN), in position 1,5 and 16, the consistent degree of spectrum is all good.When having inserted the dim light of the mechanicalness dim light filter 13 being formed by punched holes type dim light filter, known in position 5 and 16 spectrum unanimously spend deterioration, there is variation in spatial distribution.In the situation that inserted the mechanicalness dim light filter 13 being formed by punched holes type dim light filter and the light diffusion element 14 being formed by quartzy light diffusion element, the consistent degree of known spectrum significantly improves, and is similar to the spectral characteristic of the spectral intensity distribution (1SUN) of position 1.
Like this, confirmed by experiment, by using the light diffusion element 14 formed by quartzy light diffusion element, the deterioration distributing in the face being brought by dim light relevant with the uniformity in face improves.On the other hand, about spectral intensity, distribute, also by using the light diffusion element 14 being formed by quartzy light diffusion element, the consistent degree of spectrum significantly improves.That is, confirmed by experiment, by using as in the present embodiment light diffusion element 14, realized the improvement of the improvement of distribution in face and the uneven color of part.
