Description
Technical field
This utility model is related to a kind of manufacture of solar cells auxiliary device, specifically a kind of electrode of IBC batteries
Test device.
Background technology
As energy crisis is increasingly serious with environmental pollution, exploitation regenerative resource becomes countries in the world sustainable development energy
The strategic decision in source.In existing sustainable energy, solar energy is undoubtedly a kind of most cleaning, most universal and most potential replace
For the energy.Solaode, also referred to as photovoltaic cell, are a kind of semiconductor device that the luminous energy of the sun is converted into electric energy.
As it is Green Product, environmental pollution will not be caused, and be Renewable resource, so in current energy starved feelings
Under shape, solaode is a kind of novel energy for having broad based growth future.Extremely enrich as silicon materials have in the earth's crust
Reserves, photovoltaic power generation technology relative maturity, cost it is relatively low and, compare other types of commercial cells have it is of a relatively high
Conversion efficiency, therefore crystal-silicon solar cell is the main flow of current solar cell.
It is the current focus researched and developed that N-type cell has the advantages that LID is little, minority carrier life time is long, for N-type silicon chip exploitation
IBC batteries have been reached 25% conversion efficiency at present, and have been combined heterogeneous due to the design that front is unobstructed and the back side is excellent
Knot technology conversion efficiency is up to 25.6%, is current world record, therefore IBC batteries are a kind of very potential sun electricity
Pond industrialization technology.But the electrode of IBC batteries is overleaf, according to traditional probe contact and the side of vac sorb collocation
Formula, can cause fragment rate to raise, cost of manufacture raise, therefore improve means of testing be reduce IBC battery costs of manufacture it is effective
Approach.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of IBC batteries that effectively can reduce in test process
Fragment rate, so as to reduce the electrode testing device of the IBC batteries of production cost.
In order to solve above-mentioned technical problem, the electrode testing device of IBC batteries of the present utility model, including horizontal positioned
Battery to be tested, the upper surface of battery to be tested are pressed with high glass thoroughly, the lower surface of the battery to be tested have thin grid line and
Electrode, is provided with probe below battery to be tested, the top of probe is pressed on the electrode of battery to be tested.
The high glass thoroughly is float glass process safety glass.
The top of the probe is pressed on the thin grid line and electrode of battery to be tested.
After using above-mentioned structure, by the way of glass is covered, while test data reliability is ensured, can make
Battery only produces stress where electrode contact, greatly reduces the scope and size of battery stress, effectively prevent tradition
Fragment rate of the upper IBC batteries in test process, so as to reduce the fraction defective in test process so that the system of IBC batteries
Cause originally to be reduced；Meanwhile, be also convenient for test probe and contacted with thin grid line, so test is provided for various electrode fabrications
The guarantee of accuracy.
Description of the drawings
Use state schematic diagrams of the Fig. 1 for the electrode testing device of this utility model IBC batteries.
Specific embodiment
Below in conjunction with the accompanying drawings with specific embodiment, the electrode testing device of IBC batteries of the present utility model is made into one
Step is described in detail.
As illustrated, the electrode testing device of IBC batteries of the present utility model, including the battery to be tested 1 of horizontal positioned,
Battery specifically to be tested is supported by support frame positioning, after battery to be tested is placed, in the upper surface of battery to be tested 1
It is pressed with high glass 2 thoroughly, that is to say, that the surface of battery to be tested is pressed in using high glass thoroughly, one is connect with test electrode to battery
Tactile power；The lower section that the lower surface of battery to be tested 1 has thin grid line and electrode, battery to be tested 1 is provided with probe 3, probe 3
Top be pressed on the electrode of battery to be tested, employing test probe connect with the electrode of battery in the presence of glass is pushed
Touch good.
Further, the top of described probe 3 is pressed on the thin grid line and electrode of battery to be tested and electrode and thin
Grid line is all contacted, and as a example by using light transmittance being 93% float glass process safety glass, its intensity of illumination is 1075 W/m to high glass thoroughly2
Ensure that test is allowed in the range of test error in etalon optical power.
Inventor gives experimental data contrast in detail below, and draws to draw a conclusion.
Taking 1600PCS cell pieces carries out data statisticss, is divided into two groups, wherein 800 pcs are using routine IBC battery testings knot
Structure, 800 pcs are using this utility model IBC battery testing structures, this utility model IBC battery testing structures, using height in addition
Glass is pressed in battery surface thoroughly, and the glass adopted in checking reaches 93% float glass process safety glass for light transmittance, is computed providing light
It is 1075 W/m according to intensity2Which is made in the range of normal test error, it is ensured that glass is smooth to be covered in IBC battery surfaces, makes
Which gives battery one power contacted with test probe, and test probe is good with the electrode contact of battery in the presence of glass is pushed
It is good, compared to conventional IBC battery testing methods, this utility model IBC battery testing structures, fraction defective can be improved, fraction defective
0.5% can be reduced more conventional.
The IBC battery testings structure adopted by this utility model be can be seen that by above-mentioned case to realize reducing IBC
The fraction defective that the test of battery causes, this reduces the scope and size of battery stress, experience mainly due to this method of testing
The card present invention is a kind of reduction IBC battery testing process fraction defectives and the effective means for reducing IBC battery production costs.
