Description
Technical field
The utility model belongs to the preparing technical field of crystal silicon solar cell sheet, specifically relates to a kind of heating arrangement and sintering furnace of crystal silicon solar cell sheet sintering furnace.
Background technology
In the production technology of current crystal silicon solar cell sheet, the oven dry of slurry and sintering mainly carry out intensification heating by the mode of infrared lamp.Although the equipment de-sign of every and appearance etc. are all different, its mode of heating and method are all identical.
Sintering and the quality of drying directly affect the pulling force of solar battery sheet photoelectric transformation efficiency and electrode.And the quality of sintering and dries quantity shows primarily of going here and there the size of resistance in electrical property, and also to show on the value of thrust of electrode.The developing direction of sintering is that temperature fluctuation is the smaller the better, and current requirement is within ± 0.5 DEG C.Therefore the stability sintered and dry is a fatefulue impact, no matter how good other operations are done, as long as sintering and oven dry are not carried out, the efficiency of those final products and yield all can become quality and inefficient product because of sintering and the bad of oven dry, and this also illustrates the importance of this operation.General sintering and to dry good string resistance (Rs) be below 3.0mohm, good sintering just has good Ohmic contact, thus improves value and the open-circuit voltage (Voc) of fill factor, curve factor (FF), thus raising conversion ratio.Sintering temperature is more stable, then represent that front silver electrode reduces greatly to the chance that PN junction burns, burn more perfect simultaneously, decrease fraction defective, stabilize conversion ratio.With the alusil alloy that the sintering temperature of fashion can be formed in back surface field, improve the secondary reflection of light in silicon chip, and then improve absorption, the temperature sintered of therefore controlling well improves the good approach of conversion efficiency.
Current agglomerating plant be all equipment sintering or dry warm area directly insert fluorescent tube of heating, therefore when fluorescent tube start aging or burn out time, cannot change in time, needing stops equipment changes.Due to this reason, usually cause the instability of sintering, and then cause solar battery sheet efficiency to fluctuate to some extent and the generation of defective products and increase.Also can delay the product line quality of production capacity in production and other instability simultaneously.
Such as, Chinese patent CN103836940A discloses a kind of heater of sintering zone of solar battery sheet sintering furnace, comprises the transporting reticulation belt running through whole sintering furnace; Be provided with upper furnace above transporting reticulation belt, the upper surface fixed installation upper connecting rod of upper furnace, upper connecting rod top is fixedly connected on the framework of sintering zone; Below transporting reticulation belt with upper furnace symmetry be provided with lower hearth, lower hearth underrun fixed installation lower supporting rod, lower supporting rod bottom is fixedly connected on the framework of sintering zone; Upper lower hearth composition sintering is divided into six warm areas, separates upper furnace, separate lower hearth by lower clapboard between different warm area by upper spacer; Be provided with heating tube in upper furnace and lower hearth, heating tube two ends are fixedly mounted on the burner hearth sidewall of lower hearth; Heating tube is infrared quartz fluorescent tube, and infrared quartz fluorescent tube is shortwave single tube; Heating tube two ends arrange binding post, and binding post connects wire, and wire connects transformer and alarm lamp successively.The heating tube of this device selects shortwave single tube, and the efficiency of heating surface is high, quick heating, each heating tube connects heating tube failure alarm circuit, and operator can find the fluorescent tube of inefficacy immediately by the display of alarm lamp, instantaneously changing, ensure that sintering quality.But, this device still also exist when fluorescent tube start aging or burn out time need equipment to stop the technical problem carrying out changing, which results in the instability of sintering, cause solar battery sheet efficiency and fluctuate to some extent and the generation of defective products and increase.
