Photovoltaic welding ribbon<\/a>The performance parameters of the ribbon are important in their own right. The type of copper and its purity determine the conductivity of the material and the maximum degree of flexibility that can be achieved with the ribbon.<\/p>\n

1. Raytron<\/a>Innovation of new energy photovoltaic ribbon substrate<\/p>\n

Raytron<\/a>The original use of CCA instead of copper as the base material of photovoltaic ribbon has great cost advantages. If you do not require high efficiency of light conversion, CCA photovoltaic ribbon will be a good choice.<\/p>\n

Because CCA is much lighter than copper, the price per meter of CCA tape is at least 30% lower than that of copper. In addition, except for the light conversion efficiency, there are no major problems in other performance aspects.<\/p>\n

Let\u2019s take Sharp Innovation Energy\u2019s MBB ribbon as an example.<\/p>\n

Copper vs. CCA<\/p>\n

Copper (C10200) HTCCA (40HT tensile strength minimum 340Mpa minimum 340Mpa elongation minimum 1% minimum 1% conductivity 100%IACS 63%-80%IACSD density 8.9 (g\/cm3) 3.5-5.7 (g\/cm3) stretchability minimum 0.01mm0.05mm2.<\/p>\n

2. Innovation in the mechanical properties of photovoltaic ribbons<\/p>\n

High elongation of the wire is important to prevent failure of the solder joints between the bus ribbon and the interconnect bar. This failure may be caused bySolar Cells<\/a>The elongation\/tension caused by the temperature fluctuations during the operation of the panel occurs. During the service life of the solar panel, the continuous and sometimes extremely strong temperature fluctuations every day put the solder joints to the test during the service life of the solar panel (an average of 25 years).<\/p>\n

For most ribbon wire manufacturers, two parameters are critical: curvature and yield strength.Photovoltaic Ribbon Manufacturer<\/a>It has been found that it is difficult to obtain a high level of ribbon softness while maintaining straightness. Achieving adequate softness and low curvature can mean the difference between winning and losing a supply contract. As a result, manufacturers must work to improve their rolling, annealing, tinning and material handling techniques to meet the ever-increasing product performance specifications.<\/p>\n

3. Light reflective tape<\/p>\n

Because the part of the solar cell covered by the photovoltaic welding ribbon cannot absorb sunlight. In order to improve the efficiency of light utilization. Raytron has launched a light reflection ribbon. Its front side is silver-plated and has a longitudinal groove structure pressed into it. This structure reflects the light incident on the ribbon to the inner surface of the glass layer of the module at a certain angle and projects it to the surface of the cell after complete reflection at the glass-air interface. The captured light enables the module to generate additional increased power. In theory, it can increase the efficiency of the module by about 2%.<\/p>\n

4. Industry barriers for photovoltaic ribbons<\/p>\n

There are three main obstacles to the production line, namely capital, difficulty in cost control and high R&D requirements.<\/p>\n

(1) Capital barriers: The raw materials for photovoltaic welding strips are metals such as copper and tin alloys, which require a large amount of working capital investment, forming a certain capital threshold.<\/p>\n

(2) Cost control barriers: It is difficult for new entrants to achieve effective cost control. They may have insufficient yield in the production process and find it difficult to achieve the same product quality as mainstream companies.<\/p>\n

(3) R&D capability barriers: The new iteration of photovoltaic welding ribbons requires welding ribbon manufacturers to have corresponding R&D capabilities and R&D investment. New entrants are at great risk of being eliminated by the market if they do not have a complete R&D system and core technical capabilities.<\/p>\n

Under the screening mechanism of survival of the fittest, industry concentration will further increase.<\/p>\n

Photovoltaic Industry<\/a>Structural upgrades are an inevitable trend, and the performance improvement of photovoltaic ribbons has become a future development demand. With the continuous development of the photovoltaic ribbon industry, companies with insufficient financial strength, weak cost control capabilities, and backward product research and development technology will be eliminated from the market.<\/p>\n

Companies with relative advantages, such as AAC Technologies, can, on the one hand, consolidate the quality of their products through technological process optimization. On the other hand, they have the financial capacity to actively develop new products with better performance to cope with the price change trend in the product market. Ultimately, they will gain more market share. It is expected that the market share of leading companies will remain stable or increase in the future, and the competitive landscape will tend to be positive.<\/p>","protected":false},"excerpt":{"rendered":"
