Characteristics of photovoltaic welding ribbon<\/p>\n<p>Photovoltaic welding ribbon is mainly made of copper and tin alloy, and is the bridge for current transmission between photovoltaic cells. Its characteristics are mainly reflected in the following aspects:<\/p>\n<p>High conductivity: Copper and tin are both excellent conductive materials, so photovoltaic ribbons can transmit electrical energy efficiently.<\/p>\n<p>High temperature stability: In high temperature environment, photovoltaic welding ribbon can still maintain good conductivity and structural stability.<\/p>\n<p>Corrosion resistance: Photovoltaic welding ribbons must be able to remain stable in various harsh environments without oxidation, falling off, etc.<\/p>\n<p>Good weldability and processability: PV ribbons should be easy to weld and also easy to process into various shapes and sizes.<\/p>\n<figure id=\"attachment_8362\" aria-describedby=\"caption-attachment-8362\" style=\"width: 450px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-8362 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/09\/2023092115451197.jpg\" alt=\"Photovoltaic ribbons connect the main components of photovoltaic cells\" width=\"450\" height=\"300\" \/><figcaption id=\"caption-attachment-8362\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"size-full wp-image-8362 lazyload\" src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/09\/2023092115451197.jpg\" alt=\"Photovoltaic ribbons connect the main components of photovoltaic cells\" width=\"450\" height=\"300\" srcset=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/09\/2023092115451197.jpg 450w, https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/09\/2023092115451197-300x200.jpg 300w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><\/noscript> Photovoltaic ribbons connect the main components of photovoltaic cells<\/figcaption><\/figure>\n<p>2. Application of photovoltaic welding ribbon<\/p>\n<p>Photovoltaic ribbons are widely used in various types of photovoltaic modules, such as conventional photovoltaic modules, multi-grid modules, micro inverters, etc. In these modules, photovoltaic ribbons play an important role in connecting cells and transmitting current.<\/p>\n<p>Taking conventional photovoltaic modules as an example, photovoltaic ribbons are used to connect the positive and negative electrodes of the cells to form a series circuit. At the same time, they also play the role of heat dissipation and mechanical support to ensure that the cells will not fall off or be damaged when subjected to external forces.<\/p>\n<p>3. Manufacturing requirements for photovoltaic welding ribbons<\/p>\n<p>The manufacturing of photovoltaic ribbons needs to follow strict quality control standards. The following are several major manufacturing requirements:<\/p>\n<p>Raw material control: The quality of copper and tin alloys directly affects the performance of photovoltaic ribbons. Therefore, strict quality inspection and control of raw materials are required during the manufacturing process.<\/p>\n<p>Production process control: During the production process, it is necessary to precisely control process parameters such as heating, melting, extrusion, and stretching to ensure the dimensional accuracy and mechanical properties of the photovoltaic welding ribbon.<\/p>\n<p>Surface treatment: In order to improve the solderability and corrosion resistance of photovoltaic ribbons, surface treatment is required. The process and materials of surface treatment must comply with relevant standards and regulations.<\/p>\n<p>Quality inspection: Strict quality inspection is required during the manufacturing process, including size, appearance, conductivity, weldability and other inspection items. Only photovoltaic ribbons that meet quality standards can be used in photovoltaic module manufacturing.<\/p>","protected":false},"excerpt":{"rendered":"<p>In photovoltaic modules, photovoltaic ribbon is a vital component.
