Abstract
The invention discloses a kind of methods for distinguishing polycrystalline cell piece color colour system, include the following steps, step 1, it will normally produce, the good polycrystalline cell piece of printing-sintering gets out a collection of sample, quantity can try sample after running, it can be deduced that cloud atlas of this batch of sample in Lab color model between 1600-3200 piece on visual analysis instrument；Step 2 carries out the setting of classification to instrument according to cloud atlas of the sample in Lab color model, and category classification is set as standard with datum mark.The method of the differentiation polycrystalline cell piece color colour system reduces the color difference in each color classification of solar battery sheet between monolithic, and guarantees the colour consistency of subsequent components lamination.
Description
Technical field:
The present invention relates to area of solar cell, are especially a kind of method for distinguishing polycrystalline cell piece color colour system.
Background technique:
At present multicrystalline solar cells color appearance sort, mainly according to shade distinguish three colors, for it is dark blue,
It is blue, light blue.It is found in so practical control, the difference of mass colour and light tone is also had in each color, such as blue, is led
Change colour after causing component lamination, forms color difference.Reason is analyzed, first is that PECVD efficiency in order to better improve at present, for duplicature
The application of technology, the relative instability of duplicature front and back film refractive index, causes cell piece colour system to generate certain difference；Second is that
At present during diamond wire polycrystalline battery slice etching, using flocking additive, battery can be effectively controlled in making herbs into wool process control
The height of piece reflectivity, reflectivity plays deciding factor for the color after PECVD.
Summary of the invention:
The technical problem to be solved by the invention is to provide between monolithic in a kind of each color classification of diminution solar battery sheet
Color difference, and guarantee subsequent components lamination colour consistency differentiation polycrystalline cell piece color colour system method.
The technical solution of the invention is as follows, provides a kind of method for distinguishing polycrystalline cell piece color colour system, including following
Step,
Step 1 will be produced normally, and the good polycrystalline cell piece of printing-sintering gets out a collection of sample, and quantity can be in 1600-
Between 3200, sample is tried on visual analysis instrument after running, it can be deduced that cloud of this batch of sample in Lab color model
Figure；
Step 2 carries out the setting of classification to instrument according to cloud atlas of the sample in Lab color model, category classification with
Datum mark is set as standard；
Step 3 under fixed ambient brightness, images simultaneously polycrystalline cell piece using high color digit camera
Computer is stored, and color analysis is carried out to every cell piece by software, so that cell piece be divided according to shade.
Preferably, 3-4 datum mark of setting.
Using after above scheme compared with prior art, the invention has the following advantages that improving polycrystalline cell piece color
The accuracy of sorting, by the analysis to cell piece color model parameter, every cell piece has a Lab color coordinates, then
Each color classification is come out by automation equipment.
Detailed description of the invention:
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Specific embodiment:
With regard to specific embodiment, the invention will be further described with reference to the accompanying drawing:
As shown in Figure 1, a kind of method for distinguishing polycrystalline cell piece color colour system, includes the following steps,
Step 1 will be produced normally, and the good polycrystalline cell piece of printing-sintering gets out a collection of sample, and quantity can be in 1600-
Between 3200, sample is tried on visual analysis instrument after running, it can be deduced that cloud of this batch of sample in Lab color model
Figure；
Step 2 carries out the setting of classification to instrument according to cloud atlas of the sample in Lab color model, category classification with
Datum mark is set as standard；
Step 3 under fixed ambient brightness, images simultaneously polycrystalline cell piece using high color digit camera
Computer is stored, and color analysis is carried out to every cell piece by software, so that cell piece be divided according to shade.
Preferably, 3-4 datum mark of setting.Datum mark setting number with the shade for coming out whole hundred cell piece be
Subject to no enough consistency.
The setting of datum mark: in multicrystalline solar cells in the Lab color model of instrument, L value is generally lain in 20-
Between 40.As shown in Figure 1, being provided with three datum marks, the navy blue L value in the first area Ge Dian①② is set as 26, and second point is 3.
4. the L value of area's blue is set as 29, the area third Ge Dian⑤⑥ L value azury is set as 32.Multicrystalline solar cells test L value number
Word is bigger, and color is more shallow, and number is smaller, and color is deeper.The setting of a, b value will be in multicrystalline solar cells survey as far as possible
Attempt the Y-axis middle position of case, in this way far from a, b value is too many and all can be selected out far from the too many cell piece of L value, it
Color can show different abnormal colors.
B value: finding the smaller cell piece of b value in test, color is more bright-coloured；B value is bigger, and color is more blackish green.And pass through b value
Division, can as far as possible by both show color-separated.Example blue region as shown in figure 1, we are by b value greater than 100
Cell piece divides 3. area's (above dotted line) into, and cell piece of the b value less than 100 divides 4. area into.B value is greater than 103 or b value less than 96 again
Pick out, it is excessive or too small can all show different abnormal colors.
The accuracy for improving polycrystalline cell piece colour sorting as a result, by the analysis to cell piece color model parameter,
Every cell piece has a Lab color coordinates, then is come out each color classification by automation equipment.
Only the preferred embodiment of the present invention has been described above, but is not to be construed as limiting the scope of the invention.It is all
The equivalent structure or equivalent flow shift done using description of the invention, be included in scope of patent protection of the invention it
It is interior.
