Description
Technical field
The utility model relates to area of solar cell, is specifically related to a kind of sheet resistance testing arrangement for solar battery sheet.
Background technology
Conventional fossil fuel approach exhaustion day by day, in all sustainable energies, solar energy is undoubtedly the most clean, the most general and most potential alternative energy source of one.Photovoltaic generation is one of generation technology of most sustainable development desired characteristics.At present, in all solar cells, silicon solar cell is one of solar cell obtaining business promotion on a large scale, this is because silicon materials have very abundant reserves in the earth's crust, the solar cell of other types compared by silicon solar cell simultaneously, has excellent electric property and mechanical performance.In the development of following photovoltaic technology, along with the further raising of silicon solar cell photoelectric properties, the further reduction of silicon materials price, silicon solar cell will occupy consequence at photovoltaic art.
Solar battery sheet is the core of solar module.And the PN junction of solar battery sheet is the basis of photovoltaic generation, and square resistance is the key index judging PN junction quality.Prior art is tested the square resistance in interface.But the test of sheet resistance needs to carry out in darkroom, is unfavorable for the accurate location of test position, especially for selective emitting electrode structure, the measuring accuracy of differently doped regions requires higher.In addition, existing method first determines test position, then close light source and carry out sheet resistance test, makes test process complicated, not easy to operate.On the other hand, existing test probe is fixing, therefore when the sheet resistance of test battery sheet diverse location, is realized by continuous mobile silicon chip, also makes test process complicated.In addition, the pressure of the test probe pressing silicon chip of existing equipment is uncontrollable, which substantially increases pollution and the fragment rate of silicon chip.
Summary of the invention
The purpose of this utility model is to provide a kind of sheet resistance testing arrangement for solar battery sheet.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of sheet resistance testing arrangement for solar battery sheet, comprises support, mechanism for testing and objective table;
Described support is provided with guide rail, makes mechanism for testing have the freedom of motion in X-Y-Z tri-directions;
Described mechanism for testing comprises test probe, around test probe 2 ~ 4 mm region in be provided with light source;
Described mechanism for testing also comprises the pressure adjustment knob coordinated with test probe.
Above, described support is provided with guide rail, makes mechanism for testing have the freedom of motion in X-Y-Z tri-directions, thus makes any adjusting position of mechanism for testing, achieves the test of sample optional position.
Described pressure adjustment knob is for adjusting the contact of probe and silicon chip, and when reaching maximum pressure, pressure adjustment knob starts to slide, and avoids the excessive or uneven fragment problems caused of pressure of pressure.
In technique scheme, described support is provided with the guide rail in X-Y-Z tri-directions, makes mechanism for testing have the freedom of motion in X-Y-Z tri-directions.
In technique scheme, described objective table is provided with light control switch.
Preferably, described light source is LED light source.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model devises a kind of sheet resistance testing arrangement for solar battery sheet, adopts the mechanism for testing that can move freely, achieves the test of sample optional position, to avoid in test process constantly contact sample and the dirty and fragment problems brought;
2. the utility model is provided with LED light source around test probe, and solving when testing in darkroom cannot pinpoint problem, simplifies operating procedure;
3. the utility model is provided with the pressure adjustment knob knob of adjustable pressure, avoids electric probe in prior art in the excessive or uneven situation of decline procedural test pressure, effectively reduces the damage of sample, reduce fragment rate;
4. structure of the present utility model is simple, and be easy to preparation, cost is lower, is suitable for applying.
