Description
Technical field
The present invention relates to a kind of production equipment of solar battery sheet, especially a kind of solar battery sheet attenuating device that can improve the crystal silicon solar cell sheet light induced attenuation characteristic.
Background technology
Crystal silicon solar cell sheet is the main product in present photovoltaic market.Yet, owing to introduced impurity in the crystal growing process, cause dopant wherein to form complex centres to the initial stage illumination meeting of battery sheet, thereby the minority carrier life time of silicon chip is reduced with impurity such as oxygen, iron, cause the reduction of battery conversion efficiency, the generation photo attenuation.It has been generally acknowledged that and to adopt following method to solve the photo attenuation problem: 1, adopt the magnetic field Czochralski method that can reduce and control the monocrystalline oxygen content; 2, utilize the process drawing monocrystalline of zone melting single-crystal; 3, replace the crystal pulling method of boron with gallium or phosphide element as P type dopant; 4, adopt the crystal pulling method of phosphorus as N type dopant.Common cognition to these four kinds of methods is: though the oxygen content in the monocrystalline can controlled and reduce to method 1, need dispose magnetic field means at that time and its excitation power supply is provided, and will inevitably increase cost.Method 2 also can avoid in the vertical pulling technology a large amount of oxygen to get into the inherent shortcoming of silicon crystal, but cost is higher, is mainly used in the silicon chip manufacturing of IC, and just reduce cost must be to the technology transformation of being correlated with.And in the third method because the segregation coefficient problem of gallium and indium, make monocrystalline along cephalocaudal axis to change in resistance too big, influenced the monocrystalline quality, be unfavorable for suitability for industrialized production.Use the N type monocrystalline of phosphorus doping, certainly will change battery sheet production technology on a large scale, cost is also very big.
Summary of the invention
The technical problem that the present invention will solve is: propose a kind of solar battery sheet attenuating device that improves the crystal silicon solar cell sheet light induced attenuation characteristic.
The technical scheme that the present invention adopted is: a kind of solar battery sheet attenuating device; Comprise the decay casing; Described casing lower end has battery sheet conveyer belt therefrom to pass; Conveyer belt top in the described casing is provided with a plurality of illumination lamps and air jet pipe, and the below of described conveyer belt is provided with heater, and the upper end of described casing is provided with fan.
Further say, the uniformity when decaying in order to increase, illumination lamp of the present invention and air jet pipe are evenly distributed on the top of conveyer belt, and described heater is evenly distributed on the below of conveyer belt.
Further say again, have a plurality of apertures on the tube wall of air jet pipe of the present invention; Described illumination lamp is infrared lamp or metal halid lamp; Described heater is infrared pipe or the resistance wire of waiting.
The invention has the beneficial effects as follows that solved the defective that exists in the background technology, the present invention is simple in structure, easy operating is convenient to the battery slice assembly line and is used.
