Description
Technical field
The utility model relates to a kind of performance testing device for the double-sided solar battery sheet, is the auxiliary test unit that detects the battery sheet, belongs to field of solar energy.
Background technology
Conventional fossil fuel is approach exhaustion day by day, and in existing sustainable energy, sun power is undoubtedly a kind of cleaning, general and the most potential substitute energy.At present, in all solar cells, crystal silicon solar energy battery is one of solar cell that obtains business promotion on a large scale, this is because silicon materials have very abundant reserves in the earth's crust, silicon solar cell is compared the solar cell of other types simultaneously, and excellent electric property and mechanical property are arranged.Therefore, crystal-silicon solar cell in the photovoltaic field in occupation of consequence.
Because the generated output (especially output voltage) of monolithic crystal silicon solar cell sheet is lower, therefore for solar module, usually some battery sheets need be cascaded, thereby obtain higher generated output (comprising higher output voltage and electric current).The performance that is encapsulated in each monolithic battery sheet in the same assembly is more approaching, and the person can not have a negative impact to the overall performance of assembly.Therefore, before encapsulation, must carry out performance test to the monolithic battery sheet, so that according to the battery performance stepping, the cell package of same gear be become assembly.
The performance testing device of conventional solar battery sheet mainly comprises solar simulator 1, mechanism for testing and computer testing control and disposal system three parts referring to shown in the accompanying drawing 1; Wherein, mechanism for testing mainly comprises support platform 2, test probe 3 and test circuit.Solar simulator mainly provides testing light source, the solar spectrum of the spectrum of this light source during close to air quality AM1.5, irradiation intensity 1000W/m
2Mechanism for testing is to test the I-V characteristic of solar battery sheet when being subjected to light irradiation.During test, solar battery sheet 5 is placed on the support platform, the sensitive surface of battery sheet is upward to solar simulator (being light source), and two groups of test probes up and down of mechanism for testing contact with the both positive and negative polarity of battery sheet respectively, the performance of battery sheet when being used for the test light irradiation.This performance testing device is fit to the conventional batteries sheet that test has aluminium back of the body field.
On the other hand, along with going deep into of research and development, the two-sided light type solar module that is subjected to has obtained everybody approval and exploitation, and the two-sided front and back of light type battery sheet that is subjected to can be subjected to light simultaneously, therefore can utilize luminous energy more fully, realize higher opto-electronic conversion performance.Same, this class battery component also needs the battery sheet is carried out performance test.Yet, also be not specifically designed at present the performance testing device of double-sided solar battery sheet, if adopt the proving installation of above-mentioned routine, then can there are the following problems: for the two-sided light type battery component that is subjected to, from the light of battery sheet front surface incident by solar battery sheet the time, a part is absorbed and is converted into electric energy, some light generation transmission; Because the another side of double-sided solar battery assembly also can be subjected to light, namely transmitted light can enter solar battery sheet again and the secondary absorption process takes place after being reflected by backboard, thereby is electric energy with this part transform light energy; And if during the testing two-sided solar battery sheet of the proving installation that adopts above-mentioned routine, because its support platform is generally black or dark metal platform, the transmitted light that sees through the battery sheet can't form reflection, and can be absorbed by metal platform, thereby its test result can not complete reaction goes out the performance of battery sheet, so its test result is inaccurate.
Summary of the invention
The utility model purpose provides a kind of performance testing device for the double-sided solar battery sheet.
For achieving the above object, the technical solution adopted in the utility model is: a kind of performance testing device for the double-sided solar battery sheet comprises solar simulator, mechanism for testing and computer testing control and disposal system; Described mechanism for testing comprises support platform, test probe and test circuit; The upper surface of described support platform is provided with reflector layer.
The effect of described reflector layer is the transmitted light of reflecting ﹠ transmitting battery sheet, makes it to enter again the battery sheet, produces the secondary absorption process, and is converted into electric energy thus; Namely imitate out as much as possible the two-sided course of work that is subjected to light type solar module, make battery sheet to be measured have the quite good detecting result.
Described reflector layer has higher reflectivity to the light of 300 ~ 1100 nm wavelength.Further, the light for 700 ~ 1100 nm wavelength has higher reflectivity.
In the technique scheme, described support platform and reflector layer are structure as a whole.Two kinds of implementations are arranged here: (1) support platform all adopts identical reflectorized material to make with the reflection horizon; Employed back veneer material or the reflectorized material that approaches of reflecting properties with it when this reflectorized material can adopt component package; (2) upper surface of support platform carries out polishing, to obtain reflecting effect.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1, the utility model design has obtained a kind of new performance testing device that is used for the double-sided solar battery sheet, by the improvement to support platform, make it have reflection function, thereby can reflect seeing through the two-sided transmitted light of light type solar cell piece that is subjected to, make it to reenter the battery sheet and produce the secondary absorption, and be converted to electric energy, thereby can characterize the performance of double-sided solar battery sheet more exactly.
2. the utlity model has good compatible type, can directly be used for testing conventional single face battery sheet and the two-sided light type solar battery sheet that is subjected to.
3, the utility model is simple in structure, is convenient to preparation, and has good operability, practicality, is suitable for applying.
