Abstract From November 24 to 26, 2016, the 12th China Solar Grade Silicon and Photovoltaic Power Generation Seminar (referred to as 12th CSPV) was held in Jiaxing, Zhejiang. China Energy Saving Solar Technology (Zhenjiang) Co., Ltd. (hereinafter referred to as: China Energy Saving Solar Zhenjiang Company)...
From November 24 to 26, 2016, the 12th China Solar Grade Silicon and Photovoltaic Power Generation Conference (referred to as 12th CSPV) was held in Jiaxing, Zhejiang. China Energy-saving Solar Technology (Zhenjiang) Co., Ltd. (hereinafter referred to as: China Energy-saving Solar Zhenjiang Company) was invited to participate in the conference and made a special technical report on the research results of “Nano-micro-composite suede on diamond-cut polysilicon wafersâ€. It caused a lot of attention and heated discussion among the participants. 
Dr. Zhou Su, on behalf of the company, shared the report on the application of nano-composite suede on diamond-cut polycrystalline silicon wafers.
"Black Silicon Technology" is a method of preparing nano-composite structure suede on the surface of polycrystalline silicon by metal catalysis or reactive ion etching, and applying it to polycrystalline silicon solar cells to reduce the reflectance of the suede and improve the efficiency of the cell. The technology, because its surface is slightly black, is called black silicon. Now, the industry is paying more and more attention to black silicon technology and its application on diamond wire cutting silicon wafers. This technology can improve the efficiency of polycrystalline solar cells and reduce the cost. It is the competitiveness of polycrystalline solar cells. One of the effective solutions for improvement is likely to become the standard technology for polycrystalline solar cells in the future.
The energy-saving solar energy Zhenjiang company Jinang line + black silicon technology has broken through mass production, not only the product efficiency is higher, but also taking into account the cost advantage, and breaking through the technical difficulties of mass production, this technology will be to achieve polycrystalline high efficiency battery And the technological development trend of polycrystalline high-efficiency components. The energy-saving solar energy Zhenjiang Company adopts the method of diamond-cut silicon wafer combined with high-efficiency black silicon technology. On the one hand, it solves the problem of difficulty in veiling of diamond-cut silicon wafer and high reflectivity; on the other hand, optimizes the light absorption of the battery, polycrystalline The average efficiency of the battery can be increased by more than 0.6%. At the same time, through the stable process and strict control, it solves the low yield and high rework problems that have plagued the RIE technology in the industry for many years, and provides the “last mile†solution for the large-scale application of diamond wire cutting silicon wafer combined with high efficiency black silicon technology. . This technology breakthrough is at the leading level in the industry, leading the rapid development of photovoltaic efficient products.
The 12th CSPV continues the theme of the previous six conferences, and adds 13 featured topics: crystalline silicon technology and equipment, single crystal technology and applications, black silicon technology and applications, double-sided battery technology and materials, Towards25%p- Typeindustrialsiliconsolarcells, double glass module technology and application, high efficiency crystalline silicon battery and component manufacturing technology, PERC high efficiency battery and test technology, 1500V system, double-sided battery application, photovoltaic quality foundation support leader, China Zhengyin technology development, KPK backplane Special topic. The conference received high attention and attention from the photovoltaic industry. The number of people attending the opening ceremony was nearly 800. It is one of the most important academic conferences in the field of silicon materials and photovoltaic power generation in China, and it is also one of the far-reaching PV industry conferences in China and even in the world.
At such an influential CSPV meeting, China Energy Conservation Solar Zhenjiang Company demonstrated the research results of “Black Silicon Technology†in 2015 after the “Black Silicon Technology†research results were presented to the industry in 2015. It not only reflects the strong scientific research strength of China Energy Conservation Solar Energy Zhenjiang Company, but also reflects the ability to rapidly transform and apply scientific research results. It constantly refreshes the brand image, industry reputation and influence of China Energy Conservation Solar Energy, and has laid a solid brand for the company's sustainable development. Competitive strength.
