Description
Technical field
The utility model is related to the detection device of solar battery sheet, is specifically that one kind is used to detect cell piece surface oxidation
The detection means of film hydrophilicity.
Background technology
Due under action of high voltage, there is leakage current between glass and encapsulating material, leading in solar photovoltaic assembly for a long time
Cause a large amount of accumulations on cell piece surface, deteriorate the passivation effect on cell piece surface, cause FF, Isc, Voc reduction, make group
Part performance is reduced, and this is referred to as PID phenomenons.Therefore in order to solve the above problems, in cell piece during being made, ozone is utilized
Oxidized silicon chip surface, in one layer of silicon chip surface formation very thin SiO2 layers, increases battery stop sodium ion using SiO2 layers
Penetrating power, so that the generation of PID phenomenons is reduced, and the good and bad of plated film degree is then surveyed using hydrophily after detection plated film
Examination.Common test relies solely on artificial progress, and complete with range estimation to the grasp of dropper height and diffusance in test, test operation is deposited
In very big subjectivity, test result error is big.
The content of the invention
It is to solve the problem of prior art is present that the utility model, which is exactly, and is devised a kind of for detecting cell piece surface
The detection means of oxide-film hydrophilicity, it is rational in infrastructure simple, examination criteria is quantified, a variety of water droplet diffusion marks can be set
Directrix quantifies to test degree, and testing result contrast is obvious, verification is convenient, improves the quality and efficiency of detection.
The technical solution of the utility model is：A kind of detection dress for being used to detect cell piece surface film oxide hydrophilicity
Put, include the upper plate and the lower plate of carrying solar battery sheet, the center of the upper plate and the surrounding around center of fixed dropper
Provided with multiple dropper fixing holes, dropper is vertically fixed in the dropper fixing hole；The upper plate is transparent panel, its upper surface mark
There is measurement graticule；The measurement graticule is the circle with dropper fixing hole concentric.
The lower plate upper surface is provided with smooth glassy layer, and glassy layer is provided with passage.
The passage is connected by being arranged on the tracheae of lower intralamellar part, and the tracheae is circumscribed with vacuum negative pressure device.
The surrounding dropper fixing hole around center is provided with four, respectively positioned at four corners of mesuring battary piece
Place.
Regulating bolt provided with regulation bearing height between the upper plate and lower plate.
The upper plate is the acrylic board of water white transparency.
The beneficial effects of the utility model can be drawn by such scheme：Due to the clear upper panel by setting and fixed drop
Fill, the height of dropper can be stablized so that the water droplet of drippage is consistent.Can be clear by the measurement graticule set on transparent upper plate
The diffusion of water droplet below paired observation.Between upper plate and lower plate by regulating bolt connect can for adjust dropper height
Degree, and suitable height can be set to facilitate fetching battery piece, the passage connection vacuum negative pressure device that lower plate is set can put
Put after cell piece and cell piece is fixed, and destruction will not be produced to cell piece, fixed form is simple, pick and place conveniently.It is logical
Device to test is crossed, height will be artificially measured and diffusion embodies, quantified, the mistake of the different human users of reduction different time
Difference, is intuitively measured plated film quality.
As can be seen here, the utility model has substantive distinguishing features and progress compared with prior art, its beneficial effect implemented
Fruit is also obvious.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the cross section structure schematic diagram of lower plate；
Wherein, 1 is upper plate, and 2 be lower plate, and 3 be regulating bolt, and 4 be dropper, and 5 be measurement graticule, and 6 be mesuring battary piece, 7
It is passage for outer tube, 8,9 be tracheae.
Embodiment
In order to more fully understand the utility model, embodiment of the present utility model is explained in detail below in conjunction with the accompanying drawings.
Embodiment：As shown in figure 1, a kind of detection dress for being used to detect cell piece surface film oxide hydrophilicity
Put, include the upper plate 1 and the lower plate 2 of carrying solar battery sheet of fixed dropper 4, provided with regulation between the upper plate 1 and lower plate 2
The regulating bolt 3 of bearing height.The center of the upper plate 1 is provided with dropper fixing hole.Surrounding around center is provided with four drops
Pipe fixing hole, dropper fixing hole is located at four edges of mesuring battary piece 6 respectively.It is vertically fixed in the dropper fixing hole
Dropper 4；The upper plate 1 is the acrylic board of water white transparency, and the upper surface of upper plate 1 indicates measurement graticule 5；The measurement graticule 5
For the circle with dropper fixing hole concentric.As shown in Fig. 2 the upper surface of lower plate 2 is provided with smooth glassy layer, glass
Layer is provided with passage 8.The passage 8 is connected by being arranged on the tracheae 9 inside lower plate 2, and the tracheae 9 passes through outer tube 7
It is circumscribed with vavuum pump.
In use, mesuring battary piece 6 is put into the lower plate 2 of test device, opens vavuum pump and adsorbed in lower plate 2
On, prevent it from being slided in testing.Take dropper 4 to fill pure water, dropper 4 is fixed on above the position for needing to test.Drip water
On mesuring battary piece 6, the circle for measuring graticule 5 by hole periphery observes diffusion of the water droplet on cell piece surface, in rule
The diameter of sign is can spread in fixing time, then calculates plated film well, other positions test repeats this step.By device to test,
Height will artificially be measured and diffusion embodies, quantified, the error of the different human users of reduction different time is good and bad to plated film
Intuitively measured.
Described above is not that, to limitation of the present utility model, the utility model is also not limited to the example above, this skill
The variations, modifications, additions or substitutions that the those of ordinary skill in art field is made in essential scope of the present utility model, also should
Belong to protection domain of the present utility model.
