Description
Technical Field
The invention relates to a trapezoid copper-based structure of a concentrating tin-coated copper strip.
Background
At present, a tin-coated copper strip for series welding of battery pieces in the solar photovoltaic industry is based on a flat copper base strip with consistent thickness and size, and tin-based solder with the thickness of 15-30 micrometers is coated on the surface of the flat copper base strip in a plating or hot dip plating process mode, so that the purpose of welding the tin-based solder with a grid line of the battery pieces is achieved. The tin-coated copper strip is in series welding on the surface of the battery piece to shield a part of light receiving area of the battery, so that the light utilization rate is reduced. Therefore, a structure with a reflection condition is arranged on the light receiving surface of the tin-coated copper strip, so that light rays can be reflected back to the glass after passing through the reflection structure surface of the tempered glass of the assembly and irradiating the surface of the welding strip, and the light rays are reflected back to the surface of the battery again through the optical total-diffusion reflection principle, and the aim of reutilizing the light rays is fulfilled.
The existing tin-coated copper strip with the surface having the reflective structure can cause the problems of cold joint and overspray in the series welding process of the battery piece due to uneven (thicker or thinner) welding surface coating, and especially the cold joint of the back surface is particularly serious. Because the reflecting structure on the surface of the tin-coated copper strip is arranged on one side of the surface of the tin-coated copper strip, the internal stress of the tin-coated copper strip is increased after the tin-coated copper strip is stretched and welded by a series welding device, and particularly, residual stress is released between the tin-coated copper strip and a battery piece without gaps after lamination, the risks of hidden cracking, fragments and the like of the laminated photovoltaic module battery piece are easily caused, and the tin-coated copper strip with the surface isomerism is only applicable to common photovoltaics in the current industry and cannot be applied to a module of a double-glass technology. There is a need for a high efficiency concentrating tin-coated copper strip product that meets the requirements of having a reflective structure on the surface, reducing the risk of chipping after lamination and lamination, and meeting the requirements of being suitable for conventional or dual-glass assembly manufacturing, and the key for preparing such a product is the copper substrate used to prepare the high efficiency concentrating tin-coated copper strip and its surface structure design.
The publication No. CN204243063U discloses a reflective solder strip and a photovoltaic module with the reflective solder strip, wherein the reflective strip is attached to the flat front surface of the flat conventional solder strip, firstly, the surface physical section (including a solder coating) of the conventional flat solder strip is in an arc shape and uneven, the problems of infirm attaching, edge tilting and curling and the like are caused when the reflective strip is attached, and in addition, complicated procedures of the product in the mass production process cause higher cost and unstable quality.
Publication number CN204441304U discloses a hot-dip reflective solder strip, only set up solder strip one side possess indentation face (reflective surface), can not maximize the light utilization that the battery absorbed, and this kind of setting is because the solder strip thermal expansion after welding draws and draws the back stress grow and can't release the risk that leads to laminate back battery piece and hidden crack simultaneously (especially after photovoltaic module reliability mechanical load loading experiment).
Publication number CN105374885B discloses a heterogeneous high-efficiency photovoltaic solder strip, publication number CN205016540U discloses a high-utilization solder strip, and has a coupling platform structure design for reflecting surface twills and reflecting surface, and the fatal disadvantage of the design is that if a hot dip plating tinning process is adopted, tin alloy solder is filled in a groove or a coupling platform arranged on the reflecting surface, finally, the reflecting surface area of reflected light is greatly reduced and can not achieve ideal optical gain, and the product is prepared by an electroplating process mode, so that a large amount of water resource pollution and consumption exist, and a large threat is generated to human health, so that the method is not suitable for popularization of mass production, and secondly, the special production cost of the electroplating process is relatively high compared with that of the dip plating process.
Publication number CN106024959a discloses a structured high-gain reflective solder strip for solar cells, whose reflective structure cannot maximize the light utilization rate of the component cell, and whose reflective surface and solder coating of the soldering surface are two solders with different melting points, which is too ideal, and the existing technology cannot solve the problem that the surface of the same material is coated with two or more tin alloys or the cost of implementation is high, and cannot realize batch preparation.
The common characteristics of the technology are that the shape of the product is rectangular, the shape structure cannot effectively maximize the utilization rate of light rays injected into the battery, and the welding surface is a smooth surface due to the fact that the surface of the copper base belt is actually an arc surface after being plated with tin through a hot dip plating process, so that uneven coating is easy to cause cold joint, and particularly the rate of fragments is increased due to the fact that residual stress is released between a tin-coated copper belt and a battery piece without gaps after lamination.
