It is bad.The glass cover-plate that current commercialization Thinfilm solar cell assembly is used is plate glass, although being plated on its surface
One layer of antireflective coating, the sunray for being radiated at its surface can also some loss.Light can not be adjusted for it, can only
Passively receive to be irradiated the sunshine of coming, and when sunshine dies down, generated energy can reduce even zero.
Utility model content
In view of this, the utility model provide a kind of thin-film solar cells glass cover-plate, with it is existing use it is general
Logical flat glass cover plate is compared, and improves light utilization, with good light penetration and relatively low light reflectance factor,
Its condenser performance is greatly improved.
To solve above technical problem, the technical solution of the utility model provides a kind of thin-film solar cells glass
Cover plate, it includes one piece of glass substrate, and a surface of the glass substrate is that imprinting is more on smooth flat, another surface
Spacing between individual concentric circles, two neighboring concentric circles is equal, and the contact position of adjacent two concentric circles is to glass substrate inner-concave
Circular saw groove formed by falling into, the depth of circular saw groove and angle of inclination become big successively from inside to outside.Its imprinting side
Method includes but is not limited to laser, plasma etching, chemical attack, 3D printing technique etc..
Further, the center of circle of above-mentioned concentric circles is the center of glass substrate.
Further, for the light penetration of reinforcing glass cover plate, high transmittance film is provided with the surface of above-mentioned concentric circles
Layer.
Further, in order to which the light for reducing glass cover plate surfaces reflects, high transmittance film layer is upper or surface of concentric circles

The method to set up of high transmittance film layer and antireflection film layer includes but is not limited to the technological means such as plating, PVD, CVD.
The utility model utilizes prior art device, on a surface of the glass cover-plate of existing thin-film solar cells
The multiple concentric circles of imprinting, thus glass cover plate surfaces produced one layer it is equidistant do not wait deep type Fresnel Lenses micro-structural,
On the one hand the structure is acted on the convergence of light using Fresnel Lenses so that more sunrays are accumulated the film sun
Opto-electronic conversion can be carried out on battery core part PN junction, improve generated energy；On the other hand, it can converge in sunrise and at sunset
Poly- dim light, improves luminous intensity so that cell power generation does as usual progress, can extend thin-film solar cells effective within one day
Generating dutation.We can also change the etching curvature of Fresnel Lenses micro-structural to adjust according to actual plate thickness of glass simultaneously
Its focal length is saved, so as to farthest utilize sunshine.It is one layer of Fresnel Lenses due to what is made in glass cover plate surfaces
Micro-structural, its influence to glass cover-plate intensity is negligible.
Compared with prior art, the beneficial effects of the utility model are：With the existing common plane glass cover-plate phase used
Than the utility model glass cover-plate improves light utilization, and system is reflected with good light penetration and relatively low light
Number, its condenser performance is greatly improved, and is enhanced the performance of thin-film solar cells dim light generating, is improved thin film solar
The generated energy of battery, extends effective generating dutation of the thin-film solar cells within one day.
