In photovoltaic cell packaging, photovoltaic welding ribbon plays a vital role, and its quality is directly related to the transmission efficiency and reliability of photovoltaic modules.<\/p>\n<p>The main function of photovoltaic ribbon is to lead out the electric energy converted from light energy on silicon wafers and transmit it to electrical equipment, playing an important role in conducting electricity. Photovoltaic cells connected by photovoltaic ribbons are packaged with EVA film, photovoltaic glass, back film, frame and other materials to form photovoltaic modules. Photovoltaic modules are directly used in the construction of photovoltaic power generation systems.<\/p>\n<p>The performance indicators of photovoltaic welding ribbons, such as appearance, size, mechanical properties, surface structure, resistivity, etc., are important factors affecting the efficiency of photovoltaic power generation. High-quality, high-tech photovoltaic welding ribbons can not only greatly improve the power generation efficiency, but also reduce the fragmentation rate of photovoltaic cells, ensure the long-term stable operation of photovoltaic modules, and are an important way for downstream photovoltaic power generation companies to reduce costs and increase efficiency.<\/p>\n<p>The manufacturing of photovoltaic modules using photovoltaic ribbons as raw materials is in the middle of the industry chain. The photovoltaic industry chain mainly includes five major links: silicon materials, silicon wafers, solar cells, photovoltaic modules and photovoltaic application systems. In the entire photovoltaic industry chain, the manufacturing of photovoltaic modules using photovoltaic ribbons as raw materials is in the middle of the industry chain.<\/p>\n<figure id=\"attachment_8359\" aria-describedby=\"caption-attachment-8359\" style=\"width: 450px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-8359 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/09\/2023092115200228.jpg\" alt=\"Photovoltaic ribbon production equipment\" width=\"450\" height=\"300\" \/><figcaption id=\"caption-attachment-8359\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"size-full wp-image-8359 lazyload\" src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/09\/2023092115200228.jpg\" alt=\"Photovoltaic ribbon production equipment\" width=\"450\" height=\"300\" srcset=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/09\/2023092115200228.jpg 450w, https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/09\/2023092115200228-300x200.jpg 300w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><\/noscript> Photovoltaic ribbon production equipment<\/figcaption><\/figure>\n<p>The upstream of the photovoltaic welding ribbon industry is mainly suppliers of raw materials such as copper, tin alloys and flux, and the downstream customers are photovoltaic module manufacturers. Since the performance of photovoltaic welding ribbons is closely related to the tin content, the supply situation of upstream raw material suppliers has a greater impact on downstream photovoltaic module manufacturers.<\/p>\n<p>Photovoltaic welding ribbon products are rich and varied to meet different characteristics. According to the product application direction, it can be divided into interconnection welding ribbon and busbar welding ribbon. Interconnection welding ribbon is a tin-coated welding ribbon used to connect photovoltaic cells and collect and transmit the current of photovoltaic cells. It is connected to the front and back grid lines of the cell, connecting the positive and negative poles of adjacent cells to form a series circuit, transmitting the electrical energy on the cell to the electrical equipment, and at the same time playing the role of heat dissipation and mechanical manufacturing. Busbar welding ribbon is a tin-coated welding ribbon used to connect photovoltaic cell strings and junction boxes, and transmit the current of photovoltaic cell strings. It connects many cell strings to achieve a complete current path.<\/p>\n<p>For conventional photovoltaic modules, the consumption ratio of the interconnection ribbon and the bus ribbon is about 4:1; for multi-grid modules, the consumption ratio of the interconnection ribbon and the bus ribbon is about 5:1.<\/p>\n<p>According to the performance and applicable fields of photovoltaic welding ribbons, interconnection welding ribbons mainly include conventional interconnection welding ribbons, MBB welding ribbons, low-temperature welding ribbons, low-resistance welding ribbons, etc.; busbar welding ribbons mainly include conventional busbar welding ribbons, punching welding ribbons, black welding ribbons, bent welding ribbons, etc. Different types of photovoltaic welding ribbons have different characteristics and application scenarios, so when choosing, you need to combine your own needs and actual needs to make a choice.<\/p>\n<p>In general, photovoltaic ribbons, as an important component of photovoltaic modules, play an important role in improving the efficiency and reliability of photovoltaic power generation. With the continuous advancement of technology and the continuous expansion of the market, the photovoltaic ribbon industry will face more opportunities and challenges in the future. Therefore, strengthening technological research and development and innovation, and improving product quality and reliability will be an important direction for the development of the photovoltaic ribbon industry in the future.<\/p>","protected":false},"excerpt":{"rendered":"<p>Photovoltaic ribbon, also known as tinned copper ribbon or tin-coated copper ribbon, is an important component of photovoltaic modules, mainly used to connect photovoltaic cells, transmit electrical energy and form electrical devices.
