Description
Technical field
The invention belongs to technical field of solar batteries, be specifically related to a kind of method of testing for solar cell properties.
Background technology
Crystal silicon solar energy battery is the core component of solar power system, the stability of battery performance is directly connected to stability and the generated energy size of whole generating system, in daily use, have the decline that some factors cause battery performance, photo attenuation is one of them.As far back as (the Fischer and W. Pschunder seventies in last century, Proceedings of the 10th IEEE Photovoltaic Specialists Conference, Palo Alto, CA, IEEE, New York, 1973, p. 404), people just find that silicon solar cell its efficient after illumination a period of time has certain decline, be referred to as photo attenuation (Photo induced deterioration, PID) phenomenon.1997, Schmidt etc. found that the interior boron oxygen that exists of photo attenuation phenomenon and wafer bulk is compound to relevant (J. Schmidt, A. G. Aberle, and R. Hezel, Proceedings
Of the 26th IEEE Photovoltaic Specialists Conference, Anaheim, CA, IEEE, New York, 1997, p. 13).Under short time illumination, it is compound right to mix the inner meeting generation of B silicon chip B-O, forms the charge carrier recombination center, and minority carrier life time descends, thereby causes the decline of battery short circuit electric current and open-circuit voltage.The but compound right formation of this B-O and to dissociate be reversible, lucifuge annealing can be dissociated gradually under 200 celsius temperatures, and photo attenuation is recovered.Simultaneously, some impurity in the silicon chip also can cause the photo attenuation aggravation (H. Savin, M. Yli-Koski, and A. Haarahiltunen, Appl. Phys. Lett. 95,152111,2009) of battery as the existence of Cu, Fe etc.Except silicon chip sole mass factor, battery sheet manufacture craft also can cause photo attenuation generation, particularly passivation on double surfaces high-efficiency battery blade technolgy, and the quality of the stability of passivation technology and silicon chip quality directly has influence on battery photo attenuation degree.
Photo attenuation gently then causes the impaired generated energy of the final power of battery to reduce, if seriously can cause the serious mismatch of assembly battery sheet electric current, assembly property descends greatly, thus each big producer all with photo attenuation as one of direction of daily monitoring.Cell decay when at present generally only monitoring irradiance and being 5000W.h, but do not see for the monitoring of the long-term illumination decay of battery and to deliver that therefore above-mentioned influence factor is also never learnt the influence of the long-term electrical property of battery sheet.Main cause is that long-time illumination meeting causes the grid line oxidation of battery sheet so that test distortion, the easy fragmentation of battery process multi-pass operations etc., therefore be difficult to obtain the data and curves of the long-term illumination decay of battery sheet, thereby be difficult to conclude the reason place that really causes photo attenuation.
Chinese patent ZL201010105090.2 discloses a kind of battery sheet photoinduced attenuation testing system and method for testing thereof, this Design of Test System has seal box, can realize battery illumination decay under the vacuum, thereby having avoided the influence to battery sheet surface such as air, moisture, is a kind of test battery efficient ways that decays for a long time.But the drawback of this method is can not outdoor photoenvironment that is virtually reality like reality, because the vacuum requirement is arranged, the size of control box limits to some extent, is unfavorable for the operation of battery sheet in enormous quantities simultaneously.

Welding described in the step (2) and battery sheet both positive and negative polarity main grid coupling, described welding is identical with the product line or customize voluntarily according to battery types; The long-pending cross-sectional area that should be not less than used welding of described bus bar cross section.
Light source described in the step (6) is solar simulator or outdoor sunshine; During illumination, can monoblock battery directly under open loop state, shine, monolithic battery series connection and short circuit that also can each is packaged, simulation power station real work environment shines.
Initial irradiation is 0.1-20kwh in step (7) and (8), and follow-up irradiation irradiation at interval is 0.5-50kwh, should treat after illumination finishes that battery is cooled to room temperature and carries out efficiency measurement again.
Compare with existing method of testing, the present invention has following advantage:
(1) method of testing simple and feasible provided by the invention does not need to increase extra equipment, can effectively avoid in the existing test pattern grid line oxidation after the illumination of battery sheet to cause the problem of test result distortion.
(2) method of testing provided by the invention is directly applied for the monitoring of the photo attenuation of monolithic battery sheet, light decay variation tendency that can more real reaction cell itself.In the solar components factory, the big block assembly (60 or 72 batteries) of tradition also can carry out the photo attenuation experiment, if but the decay of polylith battery sheet is inconsistent, and the current/voltage matching degree is bad, is difficult to obtain battery sheet self light decay situation accurately.
