Abstract
The utility model discloses a solar single-crystal cell piece with the high light availability, belongs to the technical field of solar cells and aims to provide the solar single-crystal cell piece capable of effectively improving absorbing capacity of the sun and the light availability of the cell piece. The solar single-crystal cell piece is characterized by comprising a silicon chip substrate provided with a plurality of sine-wave-shaped lines, and grid lines and thin grid lines are arranged on the sine-wave-shaped lines and mutually perpendicular.
Description
Technical field
The utility model discloses a kind of solar energy single crystal cell piece, specifically, is the solar energy single crystal cell piece that a kind of smooth availability is high, belongs to technical field of solar batteries.
Background technology
Solar power generation is due to its environmental protection and reproducible performance, and the parent who more and more is subject to people looks at.The principle of solar cell power generation is based on semi-conductive photovoltaic effect, and solar radiation is converted into to electric energy.The solar energy single crystal cell piece that light availability in the market is high comprises silicon chip and is etched in main grid line, the grid line on silicon chip that its main grid line, a grid line are crossing straight line, and the main grid line is thicker.Solar radiation is radiated at the electric charge that produces on silicon chip by a grid line enrichment of metal, then is transferred on the main grid line, and generation current, generated electricity.But the high solar energy single crystal cell piece of light availability in the market, because the silicon chip intensity of light reflection is larger, causes most of sunlight to be reflected, so the high solar energy single crystal cell piece generating efficiency of light availability in the market is low.Make it to improve generating efficiency, the problem that the utility model people will solve just.
The utility model content
For the problems referred to above, the utility model discloses a kind of uptake of effective raising sun and the solar energy single crystal cell piece of cell piece light availability.
The technical solution of the utility model is such: the solar energy single crystal cell piece that a kind of smooth availability is high, comprise the silicon chip matrix, described silicon chip matrix is provided with many sinusoidal wave shape lines, is provided with grid line and thin grid line above the sinusoidal wave shape line, and grid line is mutually vertical with thin grid line.
The solar energy single crystal cell piece that above-mentioned light availability is high, the bearing of trend of described sinusoidal wave shape line is consistent with the bearing of trend of grid line; Described many sinusoidal wave shape lines are arranged parallel to each other.
Further, the solar energy single crystal cell piece that above-mentioned light availability is high, the wave height of described sinusoidal wave shape line is 0. 1-0.3mm.
Compared with prior art, the solar energy single crystal cell piece that the light availability that the utility model provides is high effectively improves uptake and the cell piece light availability of the sun, and the efficiency of the solar energy single crystal cell piece that the light availability is high has been improved more than 2%, and stable performance.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model principle schematic;
Wherein: silicon chip matrix 1, sinusoidal wave shape line 2, grid line 3, thin grid line 4.
Embodiment
Below in conjunction with embodiment and accompanying drawing explanation, the technical solution of the utility model is described in further detail, but does not form any limitation of the invention.
Consult Fig. 1, the high solar energy single crystal cell piece of a kind of smooth availability of the present utility model, comprise silicon chip matrix 1, and described silicon chip matrix is provided with many sinusoidal wave shape lines 2, be provided with grid line 3 and thin grid line 4 above sinusoidal wave shape line 2, grid line 3 is mutually vertical with thin grid line 4.The wave height of sinusoidal wave shape line 3 is 0. 1-0.3mm, and best wave height is 0.2mm, and described many sinusoidal wave shape lines 3 are arranged parallel to each other, and are conducive to the absorption of sunlight.Reflectance coating 2 is provided with grid line 3 and the thin grid line 4 of collected current, and grid line 3 is mutually vertical with thin grid line 4, and the bearing of trend of described sinusoidal wave shape line 3 is consistent with the bearing of trend of grid line 3.During illumination.Consult Fig. 2, due to the novel reflectance coating 2 that increased of this practicality, after being subject to the corrugated reflection while making solar light irradiation, refraction is absorbed on adjacent corrugated, has increased the availability of light, and especially, when sunlight is insufficient, its efficiency obviously improves.During manufacture, grid line 3 and thin grid line 4 cell panel manufacture method routinely, burn on cell piece main body 1 through silk screen printing, oven dry, knot, at 700 ℃ of sintering, forms.
