On October 18th, 2017, Heraeus Photovoltaic, the world's leading supplier of metallization pastes for the photovoltaic industry, launched a new type of conductive specifically developed for diamond-cut polycrystalline silicon photovoltaic cells at PV Taiwan. Silver paste. This SOL9651D series of positive silver paste is developed for the growing market demand for diamond-cut polycrystalline silicon cells, and has excellent adaptability to such special textured surface batteries. Industry analysts expect that by the end of 2018, the market share of King Kong wire-cut batteries will reach 80%. Dr. Zhang Weiming, senior vice president and chief technology officer of Heraeus Photovoltaic, pointed out that Heraeus has accelerated the development and production of SOL9651D slurry to meet the technical requirements of diamond-cut wafers and achieve superior product performance. He said: "With the emergence of technologies such as diamond cutting and the technology of choice for battery manufacturers in the photovoltaic industry, it is crucial to develop and supply the right slurry in a timely manner. With Heraeus SOL9651D slurry, battery manufacturing Businesses will be able to move forward on the road to innovation.†The introduction of the SOL9651D paste marks another milestone for Heraeus to help PV cell manufacturers improve conversion efficiency, reduce production costs and maintain technological leadership. For companies that use diamond wire to cut batteries, the specially developed SOL9651D paste offers a wide range of performance and benefits, including: · Improved conversion efficiency of diamond wire cut batteries (>0.1%) · Greatly improved main grid line Adhesion and reliability of the surface of the diamond-cut battery of the additive/MCCE/RIE texturing process. · Perfectly compatible with the ultra-fine line printing process, which can further improve the conversion efficiency of the diamond-cutting battery using the special texturing process. While improving, ensure a perfect balance between the contact performance of the metallized paste and the open circuit voltage. Suitable for single-shot, two-print and non-mesh screen printing processes. SOL9651D paste is newly developed by Heraeus. Glass chemistry with excellent adhesion helps customers optimize the design of the main grid to improve electrical performance and reduce production costs, especially for diamond-cut batteries and black silicon cells with special texturing processes. This is the case. In addition, the paste has a wide sintering process window and is particularly suitable for PERC (back passivation) photovoltaic cells. It also has excellent adhesion and is perfectly compatible with single crystal and polycrystalline silicon. According to customer feedback, the SOL9651D series of silver pastes have the ability to reduce the negative effects of carrier spontaneous emission lifetime and thus have excellent LID (photoinduced attenuation) performance.
By using the mechanical and thermal properties of glass ceramics block such as high temperature resistance, thermal shock resistance, thermal expansion and other mechanical properties, it is possible to manufacture a variety of materials that meet the mechanical requirements. Using mica's machinability and orientation, it is possible to produce high-strength and machinable glass ceramics. As a mechanical mechanics material, glass ceramics can be widely used in pistons, rotating blades and cookware, and can also be used as structural materials for aircraft, rockets, and artificial satellites.
