Abstract
The utility model discloses a kind of back contact solar cell testboard, belong to back contact solar cell technical field, it comprises testboard body, testboard body is provided with test probe and suction hole, testboard body is provided with at least one closed fence higher than test probe and suction hole, suction hole is all positioned at the region that fence crosses, and during test, tested battery lid makes each fence area all become enclosure space on fence.The utility model structure is simple, easy to use, can improve the absorption affinity of testboard to cell panel, prevent the tested probe of solar panel from backing down, be particularly useful for generating electricity on two sides back contact battery, very practical.
Description
Technical field
The utility model relates to back contact solar cell technical field.
Background technology
Solar cell is a kind of semiconductor device, and it can be electric energy light energy conversion, and the polycrystalline solar cell of monolithic 6 cun can produce the electric current of about 8 to 9 amperes, the operating voltage of 0.5V, the power of 4W.Usually will detect for solar battery product, existing testboard mainly comprises testboard body, test probe and flat.The electrode contact of test probe and solar battery sheet during test, can produce touch voltage during contact, and the size of this touch voltage and stability all can affect the certainty of measurement of cell piece conversion efficiency.
At present, the solar panel testboard that prior art provides is when measuring positive and negative electrode full back contact solar cell all overleaf, all test probes all must be placed on below cell piece, and with glass, cell piece is pressed on probe, then make sunlight from passing glass, thus impinge upon the upper surface of cell piece.The shortcoming done like this is: glass can reflect away a part of sunlight, and the actual light intensity arriving cell piece surface does not reach the numerical value preset, and this just have impact on the accuracy of measurement.
Also have a kind of negative-pressure adsorption-type testboard, this testboard forms negative pressure by suction hole air-breathing, thus is inhaled on testboard by solar panel.But, the backplate of generating electricity on two sides back contact battery is open electrode structure, there is the difference in height of at least tens microns in electrode zone and non-electrode region, the part in non-electrode region can not fit tightly with testing stand, produce " gas leakage " phenomenon, cause the negative pressure between testing stand and solar cell not enough, the Mechanical Contact power that probe produces can not be offset completely, cause probe generation reliable electrical contact before by solar cell top from testing stand, affect solar cell electric parameters testing result.
Application number be 201320550381.1 Chinese patent disclose a kind of full back contact solar cell testboard, this patent overcomes the problems referred to above, but there is baroque defect.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of back contact solar cell testboard is provided, it has added fence on testboard body, improve the air-tightness of binding domain, improve absorption affinity, the problem that can prevent the tested probe of solar panel from backing down, especially solves generating electricity on two sides back contact battery absorption problem loosely.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of back contact solar cell testboard, it comprises testboard body, testboard body is provided with test probe and suction hole, in addition, testboard body is also provided with at least one closed fence higher than test probe and suction hole, suction hole is all positioned at the region that fence crosses, and during test, tested battery lid makes each fence area all become enclosure space on fence.
As preferably, fence is rubber ring.
As preferably, fence is the bulge-structure on testboard body, and namely fence is a part for testboard body.
As preferably, fence has three.
The beneficial effect adopting technique scheme to produce is: the utility model structure is simple, easy to use, it has added fence on the basis of existing negative-pressure adsorption-type testboard, improve the air-tightness of binding domain, thus improve absorption affinity, can prevent the tested probe of solar panel from backing down, be particularly useful for generating electricity on two sides back contact battery, very practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model in embodiment 1;
Fig. 2 is structural representation of the present utility model in embodiment 2.
In figure: 1, testboard body; 2, suction hole; 3, test probe; 4, fence.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, a kind of back contact solar cell testboard, it comprises testboard body 1, testboard body 1 is provided with test probe 3 and suction hole 2, testboard body 1 is also provided with closed fence 4, fence 4 is higher than test probe 3 and suction hole 2, and fence 4 is the bulge-structures on testboard body 1, it is a part for testboard body 1, and test probe 3 and suction hole 2 are all positioned at the region that fence 4 crosses.
Be placed on fence 4 by tested cell panel during test, tested cell panel makes fence area become an enclosure space, therefore, it is possible to improve the air-tightness of fence area, thus improves absorption affinity, prevents the tested probe of solar panel from backing down.
Embodiment 2:
As shown in Figure 2, a kind of back contact solar cell testboard, it comprises testboard body 1, testboard body 1 is provided with test probe 3 and suction hole 2, testboard body 1 is also provided with three closed fences 4 higher than test probe 3 and suction hole 2, fence 4 is rubber ring, and test probe 3 is positioned at outside fence area, and suction hole 2 is positioned at fence area.
Be placed on fence 4 by tested cell panel during test, rubber ring fence 4 can improve the air-tightness of binding domain, thus improves absorption affinity, prevents the tested probe of solar panel from backing down.
The utility model structure is simple, easy to use, can improve the absorption affinity of testboard to cell panel, prevent the tested probe of solar panel from backing down, be particularly useful for generating electricity on two sides back contact battery, very practical.
