Abstract
The invention discloses a production process for a photovoltaic cell assembly. The production process is characterized by comprising the following steps of: testing a single bracket; welding the anode and cathode of a photovoltaic cell chip; overlapping; detecting a photovoltaic cell assembly; and laminating, curing and framing. In the production process, framing is performed along the top angle lines of the four corners of a frame, so that the framing time of a single piece is shortened, the connection is firm, the verticality of the periphery of the frame is high, great convenience is brought to the splicing of a photovoltaic cell matrix, and the working efficiency is increased by 70 percent. In a laminating process, bubbles are not generated in the melting process of EVA (Ethylene Vinyl Acetate), so that the quality of the photovoltaic cell assembly is improved, the efficiency of conversion of solar energy to electric energy is effectively ensured, and the service life of the photovoltaic cell assembly is prolonged.
Description
Technical field
The production technology of a kind of photovoltaic cell component of the present invention, what relate to is the technical field of photovoltaic cell capable of generating power, is applied to photovoltaic generation.
Background technology
At present, the technical process of the production of domestic photovoltaic cell component comprises the test of monolithic stepping, the welding of photovoltaic cell sheet positive and negative electrode, and lamination, lamination solidifies, the technical process of group frame.In the whole technical process; Stepping with the photovoltaic cell monolithic according to the electrical property stepping; The photovoltaic cell monolithic that performance is close is combined to form the photovoltaic cell group sheet of maximal efficiency through welding, for guaranteeing photovoltaic cell group sheet service life, generally sends into laminating machine laminating with the structure of TPT-EVA-photovoltaic cell group sheet-EVA-toughened glass lamination; Fusing EVA makes photovoltaic cell group sheet, TPT, bonding being integral in the seamless unoccupied place of toughened glass; Be inserted in seal washer then around the photovoltaic cell group sheet behind lamination, the frame fixation photovoltaic cell group sheet of forming with aluminium alloy synthesizes photovoltaic cell component.Because the unreasonable allocation of whole technical process as long as a slice is damaged in the photovoltaic cell group sheet, causes photovoltaic cell component normally to use; Or, cause in the photovoltaic cell group sheet behind the lamination bubble numerous because of lamination does not pass a test, and interlayer is bonding not firm, has reduced the conversion efficiency of photovoltaic cell, and is prone to aging, corrosion, and defectives such as shortening in useful life have been wasted a large amount of energy and capital fund.Also have when the group frame; The angle connector position boring of hollow frame bar side; The screw on way fixed frame of self-tapping screw, generation be connect not firm, assembling efficiency is low, the perpendicularity around the framework is poor, brings actual difficulty for assembly unit photovoltaic cell square formation.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective; Design one cover improves the quality of photovoltaic cell component; Effectively guarantee that photovoltaic cell component becomes the transformation efficiency of electric energy with conversion of solar energy, prolong the production technology of a kind of photovoltaic cell component in photovoltaic cell component useful life.It is characterized in that: its technology, comprise the test of monolithic stepping, the welding of photovoltaic cell sheet positive and negative electrode, lamination, photovoltaic cell group sheet detects, and lamination solidifies, the technical process of group frame; Described lamination solidifies, for stop up on closing before the lid vacuumize-close the lid back stop up down vacuumize-descend stop up intensification-on stop up the air inlet lamination-under stop up air inlet cooling or water flowing cooling work table top-on stop up and bleed-technical process of curing oven; On stop up vacuumize air pressure range-0.01Mpa～-0.03Mpa between; Under stop up vacuumize air pressure range-0.04Mpa～-0.07Mpa between; The temperature of stopping up intensification down is between 110 ℃～130 ℃; Curing time, the pressure of lamination was between 10Mpa～30Mpa between 15min～30min; Described group of frame adopts the angle connector and the hollow metal bar of band damping tooth to organize frame through Frame assembling machine or corner combining machine; The Frame assembling machine of group frame or the operating pressure of corner combining machine are between 5Mpa～15Mpa.Obvious advantage and the effect implemented after this technology are: overcome existing single angle and assembled the angle connector position boring from the sheth side again; The defective workmanship of screwing on the self-tapping screw fixed frame is organized frame from the corner angle staff direction of four jiaos of frameworks, has shortened the time of single-piece group frame; It is firm to connect; Perpendicularity around the framework is high, is very easy to the assembly unit of photovoltaic cell square formation, increases work efficiency 70%.Before laminating machine in lamination process heats up; Before EVA does not also melt; Air between the photovoltaic cell component lamination of lamination is taken out to the greatest extent, can not produced bubble, improved the quality of photovoltaic cell component in fusion process; Guaranteed that effectively conversion of solar energy becomes the transformation efficiency of electric energy, has prolonged the useful life of photovoltaic battery panel.
