Abstract
The invention relates to a tooling equipment used in one side texturization of monocrystalline silicon solar cell. The tooling equipment is composed of a top board and a PVC thin plate. The top board is a rectangular flat plate, and the PVC thin plate is arranged below the top board and has a dimension identical to that of silicon chip. According to the invention, compared with the prior art, effect of one side texturization can be realized, providing the produced cell an effect that a right side of the cell can absorb more light and a back side thereof can form a good AL-BSF. Therefore, performances of the solar cell type are improved.
Description
Technical field
The present invention relates to solar cell and make the field, especially relate to a kind of tooling device that in the making herbs into wool of single crystal silicon solar cell single face, uses.
Background technology
Solar cell is an electric energy with solar energy converting as emerging clean reproducible energy directly because of having, and the life-span is long, it is simple to safeguard, can realize advantage such as unattended operation and get most of the attention.Solar power supply system has been obtained application more and more widely.
In the preparation process of single crystal silicon solar cell; Making herbs into wool through aqueous slkali and silicon chip surface reactions such as NaOH or KOH, utilizes the characteristics of monocrystalline silicon anisotropic as first procedure; Prepare the surface of pyramid pattern; Thereby increase the absorption of light, improve battery conversion efficiency greatly, traditional process for etching has all formed the matte of pyramid pattern on the silicon chip two sides.At cell backside,, further improve battery conversion efficiency thereby improve battery the two poles of the earth electrical potential difference through a printing sintered aluminium back of the body formation P+ district.But in the preparation process of the aluminium back of the body, silicon chip surface is smooth more can prepare the good aluminium back of the body more.
Summary of the invention
The object of the invention is exactly the tooling device that in the making herbs into wool of single crystal silicon solar cell single face, uses that provides a kind of performance that makes the battery sheet to get a promotion in order to overcome the defective that above-mentioned prior art exists.
The object of the invention can be realized through following technical scheme:
A kind of tooling device that in the making herbs into wool of single crystal silicon solar cell single face, uses is characterized in that this tooling device is made up of top board and PVC thin plate, and described top board is the flat board of rectangle, and described PVC thin plate is located at the below of top board, size and silicon chip measure-alike.
Described PVC thin plate is provided with 25, is set in parallel in the below of top board.
Described PVC gauge of sheet is 200 microns.
Compared with prior art, the present invention can reach the effect of single face making herbs into wool, makes the battery of producing both satisfy the more light of positive absorption, and the back side forms the effect of good aluminium back of the body field, and the performance of battery sheet is got a promotion.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 is that top board, 2 is the PVC thin plate among the figure.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
A kind of tooling device that in the making herbs into wool of single crystal silicon solar cell single face, uses; Its structure is as shown in Figure 1, and this tooling device is made up of top board 1 and PVC thin plate 2, and top board 1 is the flat board of rectangle; PVC thin plate 2 is provided with 25 altogether; Be set in parallel in the below of top board 1, size and silicon chip measure-alike, thickness is 200 microns.
At first use common frock to carry out silicon chip during use and go the affected layer operation.This frock is the PVC material, is made up of the groove of 25 500 μ m.Then, when process for etching, the present invention is inserted in the gaily decorated basket, silicon chip one side and solution are isolated, thereby form matte when avoiding technology overleaf.
Single face making herbs into wool battery sheet and two-sided making herbs into wool battery piece performance through this frock preparation are more as shown in table 1, and performance obtains 0.1% lifting.
