Abstract
The utility model discloses a kind of solar battery sheet, comprise cell piece body, cell piece body is square, cell piece body is provided with many main gate line and many thin grid lines, main gate line is vertical with thin grid line to be arranged, the width of main gate line is greater than the width of thin grid line, and the radical of thin grid line is more than the radical of main gate line, and main gate line is spun tapered head and the tail be formed by connecting by multiple.Spin by multiple the light-receiving area that main gate line that tapered head and the tail are formed by connecting can increase cell piece body, reduce silver slurry consumption, reduce production cost; Thin grid line is comparatively thin, and can increase the light-receiving area of cell piece, the radical of thin grid line is more, then the distance between thin grid line is less, and the distance of photo-generated carrier process is reduced, and the loss of resistance institute negative electrode reduces, thus adds the conversion efficiency of solar battery sheet.
Description
Technical field
The utility model belongs to helioplant field, more specifically relates to a kind of solar battery sheet.
Background technology
Solar battery sheet also claims photovoltaic cell, is a kind of semiconductor devices luminous energy of the sun being directly converted to electric energy.Because it is Green Product, can not cause environmental pollution, and be renewable resource, so under current energy starved situation, solar energy is a kind of novel energy having broad based growth future.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides the solar battery sheet that a kind of conversion efficiency is higher.
In order to reach above-mentioned technique effect, the technical solution of the utility model is as follows:
A kind of solar battery sheet, comprise cell piece body, cell piece body is square, cell piece body is provided with many main gate line and many thin grid lines, main gate line is vertical with thin grid line to be arranged, the width of main gate line is greater than the width of thin grid line, and the radical of thin grid line is more than the radical of main gate line, and main gate line is spun tapered head and the tail be formed by connecting by multiple.
In some embodiments, cell piece body is provided with 85 thin grid lines, and the width of thin grid line is 44um.
In some embodiments, the material of main gate line and thin grid line is silver slurry.
In some embodiments, main gate line is welded on the surface of solar battery sheet body, and thin grid line is welded on the surface of solar battery sheet body.
Its beneficial effect is: spin by multiple the light-receiving area that main gate line that tapered head and the tail are formed by connecting can increase cell piece body, reduce silver slurry consumption, reduce production cost; Thin grid line is comparatively thin, and can increase the light-receiving area of cell piece body, the radical of thin grid line is more, distance then between thin grid line is less, the distance of photo-generated carrier process is reduced, and the loss of resistance institute negative electrode reduces, thus adds the conversion efficiency of solar battery sheet.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is the structural representation of a kind of solar battery sheet of the utility model one embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of solar battery sheet, comprises cell piece body 1, and cell piece body 1 is square.Cell piece body 1 is provided with many main gate line 2 and many thin grid lines 3, and main gate line 2 is vertical with thin grid line 3 to be arranged.The width of main gate line 2 is greater than the width of thin grid line 3, and the radical of thin grid line 2 is more than the radical of main gate line 3.Main gate line 2 is spun tapered head and the tail be formed by connecting by multiple.Cell piece body 1 is provided with 85 thin grid lines 3, and the width of thin grid line 3 is 44um.The material of main gate line 2 and thin grid line 3 is silver slurry.Main gate line 2 is welded on the surface of solar battery sheet body 1, and thin grid line 3 is welded on the surface of solar battery sheet body 1.
Spin by multiple the light-receiving area that main gate line 2 that tapered head and the tail are formed by connecting can increase cell piece body 1, reduce silver slurry consumption, reduce production cost; Width is that the thin grid line 3 of 44um is thinner, the light-receiving area of cell piece body 1 can be increased, the radical of 85 on single battery sheet body 1 thin grid lines 3 is more, distance then between thin grid line 3 is less, the distance of photo-generated carrier process is reduced, the loss of resistance institute negative electrode reduces, thus adds the conversion efficiency of solar battery sheet.
Above-described is only the preferred embodiment of a kind of solar battery sheet of the utility model; it should be pointed out that for those of ordinary skill in the art, under the prerequisite not paying creative work; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
