Description
Technical field
The present invention provides a kind of optical microstructures curtains, and particularly providing one kind can either resist external environmental light to interfere,
The positive throwing optical microstructures curtain using perovskite thin film solar cell that luminous energy is converted into electric energy can be absorbed again simultaneously, is belonged to
In optical material technical field.
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, and solve ambient light just seems outstanding to the interference of drop shadow effect
It is important.
In existing optics curtain, U.S. patent Nos US6842282B2 is combined using soot layer and grating layer
Structure be used in combination the blacking side wall of grating to absorb component environment light using the traceability reflex characteristic of glass microballoon, improve throwing
The contrast of shadow image, but since the glass microballoon intrinsic feature of characteristic of tracing to the source makes part reflection light offset direction 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 on 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 the invention
It is more low to absorb layer material extinction efficiency, under the outdoor environment of high brightness, ambient light influences projected picture still more tight
Weight, picture contrast, color rendition degree are all a greater impact, and the light reflected from metal medium minute surface reflective membrane cannot
It is all introduced into diffusing reflection layer, this makes some light lose, and has large effect to drop shadow effect.
The sunray slatterned will should be reflected using solar cell to be used to that energy can be improved for screen power generation
Utilization ratio while improve screen saturation degree and image reduction degree.
Invention content
The present invention provides a kind of positive throwing optical microstructures curtain using perovskite thin film solar cell, solve existing
There is the deficiency in technology, which can greatly improve the absorbability to environmental disturbances light so that curtain is in bright light environments
It down can be with the reduction institute projected picture of high contrast high saturation；Light-absorption layer can also convert the luminous energy absorbed to electricity simultaneously
It can power again to projecting apparatus later, energy conservation and environmental protection.
Technical solution is used by realizing above-mentioned purpose of the present invention：
A kind of positive throwing optical microstructures curtain using perovskite thin film solar cell includes at least PET base layer, institute
The top for stating PET base layer is printed with one layer of UV light oil reservoir by way of intaglio printing, and the longitudinal section of the UV light oil reservoirs is in
Zigzag, the serrated crosssection are made of ramp and lower inclined plane, and ramp, lower inclined plane and PET base layer collectively constitute one
A triangular structure, and lower inclined plane is located at the lower section of ramp；In the triangular structure between ramp and PET base layer
Angle be 30~90 degree, depth is 100~400 microns, in the triangular structure between lower inclined plane and PET base layer
Angle be 30~65 degree；
Perovskite thin film solar cell is attached on the ramp, the perovskite thin film solar cell is under
It is supreme to be made of successively transparent substrates, FTO layers, electron transfer layer, perovskite photosensitive layer, hole transmission layer and metal electrode layer,
Transparent substrates stickup is fixed on ramp, and metal electrode layer is located at the top, when extraneous ambient light is irradiated from all angles
It is absorbed when to perovskite thin film solar cell, perovskite thin film solar cell converts the solar energy absorbed to electricity
Energy.
The depth of the ramp is 230 microns.
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.
Compared with prior art, the present invention has the following advantages：1, for the present invention in the environment of high brightness, ambient light is from each
When in a angular illumination to perovskite thin film solar cell, light is absorbed by battery.And the light gone out when projector projects from
When obliquely downward is projected on curtain, light projects on lower inclined plane, and the UV light oil reservoirs that lower inclined plane is high reflectance, and described
Angle between lower inclined plane and PET base layer is 30~65 degree, therefore the light that projecting apparatus is projected enters people after reflection
Eye.So ring of the positive throwing optical microstructures curtain provided by the present invention using perovskite thin film solar cell in high brightness
Still the high contrast and color rendition degree of institute's projected picture can be kept in border.2, perovskite thin film solar cell will be extraneous
After light absorption, further it can also convert the luminous energy absorbed to electric energy, and certain electric power branch can be provided for projecting apparatus
Support, energy conservation and environmental protection.
