Description
Technical field
The invention provides a kind of optical microstructures curtain, and particularly providing one kind can either resist external environmental light to disturb,
And can enough absorbs the positive throwing optical microstructures curtain based on thin-film solar cells that luminous energy is converted into electric energy simultaneously, belongs to optics
Field of material technology.
Background technology
Projection screen is under daylight or light influence, and contrast, the saturation degree of institute's projected image are greatly reduced, and color is also
Originality is undesirable, therefore projection screen is used under high-brightness environment, solves interference of the ambient light to drop shadow effect and just seems outstanding
To be important.
In existing optics curtain, U.S. patent Nos US6842282B2 is combined using soot layer and grating layer
Structure, absorb component environment light using the traceability reflex characteristic of glass microballoon, and with the blacking side wall of grating, improve throwing
The contrast of shadow image, but due to glass microballoon trace to the source characteristic it is intrinsic the characteristics of make it that part reflection light offset direction is excessive,
Projected image brightness drastically declines, and picture brightness loss is serious.Chengdu Fscreen Science ＆ Technology Co., Ltd.'s patent of invention
CN104062839A uses the structure that metal medium minute surface reflective membrane and microprism array structure layer and diffusing reflection layer are combined,
Absorbed layer is added in a side wall of microprism array structure layer to absorb ambient light, metal medium minute surface reflective membrane is by high
Specular reflectivity, for improving picture gain so that projected picture has good contrast, but light used in this invention
It is more low to absorb layer material extinction efficiency, under the outdoor environment of high brightness, ambient light influences still more tight on projected picture
Weight, picture contrast, color rendition degree are all a greater impact, and the light reflected from metal medium minute surface reflective membrane can not
Diffusing reflection layer is all introduced into, this causes some light to lose, and has large effect to drop shadow effect.
The content of the invention
The invention provides a kind of positive throwing optical microstructures curtain based on thin-film solar cells, solves prior art
In deficiency, the curtain can be greatly enhanced the absorbability to environmental disturbances light so that curtain can be with bright light environments
The reduction institute projected picture of high-contrast high saturation；The luminous energy absorbed can also be converted into after electric energy by light-absorption layer simultaneously
Projecting apparatus is powered again, energy-conserving and environment-protective.
Technical scheme is used by realizing above-mentioned purpose of the present invention：
A kind of positive throwing optical microstructures curtain based on thin-film solar cells, including at least PET base layer, the PET
The triangular shape thin-film solar cells being distributed in microarray, adjacent two triangular shape thin film solar electricity are provided with basalis
Spacing between pond is not more than the 1/2 of projected image pixel；The longitudinal section of the triangular shape thin-film solar cells is triangular in shape
Structure, the angle in the triangular structure between ramp and PET base layer is 30~90 degree, lower inclined plane and PET base layer
Between angle be 30~65 degree；The thin-film solar cells is made up of each level stacked on top of one another, wherein positioned at bottommost
Level be metal back electrode, the level positioned at top is tco layer, the equal triangular shape in longitudinal section of each level, and each three
It is angular to have a common summit；One layer of glass substrate is provided with the tco layer, the upper top surface of the glass substrate is cambered surface
Shape, for gathering the external environmental light come from oblique upper irradiation, and transmitted after ambient light is gathered to thin-film solar cells, it is thin
Film solar cell is by the light absorption and is converted into electric energy；The light that the metal back electrode will can come from obliquely downward irradiation
Line is reflected.
Angle between the ramp and PET base layer is 35 degree, and the angle between lower inclined plane and PET base layer is 55
Degree.
Described thin-film solar cells is amorphous silicon thin-film solar cell, cadmium telluride diaphragm solar battery, dyestuff
It is sensitized thin-film solar cells, gallium arsenide film solar cell or copper-indium-galliun-selenium film solar cell.
Compared with prior art, the present invention has advantages below：1st, the present invention is in the environment of high brightness, and ambient light is from each
When above individual angular illumination to glass substrate, because the upper top surface of glass substrate is cambered surface, therefore it can gather and be shone from oblique upper
The external environmental light come is penetrated, and is transmitted after ambient light is gathered to thin-film solar cells, thin-film solar cells is by the light
Line absorption.And when the light that projector projects go out is projected on curtain from obliquely downward, light is projected on lower inclined plane, and oblique
Face and can is enough to be reflected the light come from obliquely downward irradiation, therefore the light that projecting apparatus is projected enters people after reflection
Eye.So the positive throwing optical microstructures curtain provided by the present invention based on thin-film solar cells in the environment of high brightness still
The high-contrast and color rendition degree of institute's projected picture can so be kept.2nd, thin-film solar cells is gone back after extraneous light absorbs
The luminous energy absorbed further can be converted into electric energy, certain electric power support, energy-conserving and environment-protective can be provided for projecting apparatus again.
Brief description of the drawings
Fig. 1 is the vertical section structure figure of optical microstructures curtain provided by the invention；
In figure：1-PET basalises, 2-TCO layers, 3- metal back electrodes, 4- glass substrates.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment does detailed specific description to the present invention, but protection scope of the present invention
It is not limited to following examples.
The structure of positive throwing optical microstructures curtain provided by the present invention based on thin-film solar cells as shown in figure 1,
The triangular shape thin-film solar cells being distributed in microarray, adjacent two triangular shape films are provided with the PET base layer 1
Spacing between solar cell is not more than the 1/2 of projected image pixel.The longitudinal section of the triangular shape thin-film solar cells
Structure triangular in shape, the angle in the triangular structure between ramp and PET base layer is 30~90 degree, lower inclined plane with
Angle between PET base layer is 30~65 degree；In the present embodiment preferably, between the ramp and PET base layer
Angle is 35 degree, and the angle between lower inclined plane and PET base layer is 55 degree.
The thin-film solar cells is made up of each level stacked on top of one another, wherein the level positioned at bottommost is carried on the back for metal
Electrode 3, the level positioned at top are tco layer 2.The equal triangular shape in longitudinal section of each level above, and each triangle has one
Individual common summit；One layer of glass substrate 4 is provided with the tco layer, the upper top surface of the glass substrate is arc surfaced, is used for
Gather the external environmental light come from oblique upper irradiation, and transmitted after ambient light is gathered to thin-film solar cells, the film sun
Energy battery by the light absorption and is converted into electric energy；The metal back electrode can be carried out the light come from obliquely downward irradiation
Reflection.
In the present embodiment, described thin-film solar cells be amorphous silicon thin-film solar cell, Cadimium telluride thin film too
