Polaris Solar Photovoltaic Network News: Recently, the "China New Energy Innovation Drive Annual Conference---China International Photovoltaic Industry Innovation Technology Application Conference" held in Beijing and the "China PV Industry Power Station Transaction and Financial Summit" held in Shanghai, the world famous Dow Corning, a leader in silicone materials, announced that it has introduced a new solar cell package solar cell solution and said it has been successfully applied.


According to Dow Corning, the performance advantages of this product compared to the current packaging materials are concentrated in long-term UV radiation resistance, a wide temperature range, corrosion resistance, ultra-transparency and electrical insulation properties. Moreover, silicone battery packaging materials can significantly reduce the overall cost of solar modules, and the cost reduction is mainly reflected in the fact that silicone can allow more light sources to enter the battery, compared with the traditional EVA laminated structure, the conceptual liquid packaging process The demand for capital and labor intensity is low, silicone has good stability under ultraviolet light, its durability is equivalent to or even exceeds the existing organic battery packaging materials, and the overall cost can be realized in the miscellaneous value chain of liquid packaging materials. Savings.






At the venue of the "China PV Industry Power Station Transaction and Financial Summit", Dow Corning demonstrated the double-glass components encapsulated in liquid silicone with their customers, which attracted great interest from the participants. The component has an excellent appearance and looks more transparent than EVA. The thin aluminum strips around it, the white reflective coating on the cell gap, and the clear cell make the entire assembly look high-end and atmospheric.


On Dow Corning's official website in China, Dow Corning believes that with silicone packaging, it can produce high-performance solar modules that can withstand harsh environments, ensuring long-term stability of photovoltaic modules in harsh environments. Dow Corning Silicone Encapsulants significantly improve the durability and corrosion resistance of solar modules while preventing delamination. Use Dow Corning Solar Encapsulant to ensure improved solar module performance.


The Dow Corning PV-6100 package series leverages the UV resistance of silicone molecules to significantly enhance the following advantages of crystalline silicon cell components: more durable and more efficient. The product uses liquid processing technology to effectively reduce the overall production cost of crystalline silicon and amorphous silicon thin film battery components: lower capital costs and lower processing costs, increasing production efficiency.


In fact, since 2009, Dow Corning has established a new solar energy solution application center in Korea, and introduced new packaging materials and processing solutions. In the same year, it established a solar energy solution application and commercial center in Newwark, California. At the SNEC exhibition in 2012, Dow Corning also introduced the advantages and technological routes of silicone packaging materials to Chinese customers in the form of pictures and videos. Dow Corning believes that silicon-based materials are very suitable for solar applications, and the company has been working on the research of silicone solar packaging materials in order to become a material base for the solar industry.


In order to realize the practical application of liquid silicone material in the production of components, BYD, a well-known enterprise in the United Nations, has jointly developed this double-glass component, which is said to be the world's first industrial production of double-glass components using liquid silicone materials. Details on how to use liquid materials for component lamination processes were not disclosed at the seminar, and the introduction documents were not provided to the conference organizers. It seems that the application of the technology is still strictly confidential. But careful netizens have found some clues from the Internet. The following image is from the information collected by the well-known PV microblogging “Fingertips PV” on its Tencent Weibo.
