Improve the efficiency of solar cell conversion is imminent

In recent years, China's solar photovoltaic industry has grown at a rapid rate, and it has become the world's largest solar cell producer. However, compared with countries with more mature solar energy application markets, such as Germany and the United States, China's solar energy application market is lagging behind. Over 90% of China's PV modules are exported abroad. Affecting the promotion and application of solar cells in addition to policy reasons, but also because of its high cost, once the cost of photovoltaic power generation can compete with conventional energy (coal, oil, natural gas), or even lower than wind energy, then the domestic market will Large-scale startup. Therefore, further reducing the manufacturing cost is the key to the large-scale application of solar cells. According to industry sources, improving solar cell conversion efficiency is one of the effective ways to reduce costs. It is understood that the conversion efficiency will increase by 1% and the cost will decrease by 7%.

Recently, Linuo Photovoltaic Group and IBM announced in Jinan, Shandong, that they would cooperate in crystalline silicon cell technology and improve solar cell conversion efficiency through technological innovation. Li Shengmao, a senior research fellow at China Investment Consulting Co., Ltd., said: “The photoelectric conversion rate is one of the two core technical indicators of solar photovoltaic cells. At present, the average photoelectric conversion efficiency of domestic monocrystalline silicon cells is about 18%. As companies face greater and greater The pressure of cost and the increase in the profitability of the industry in the future will depend on breakthroughs in related technologies."

In fact, improving the efficiency of battery conversion and reducing manufacturing costs has always been the goal of the industry's manufacturers. At present, all photovoltaic manufacturers in China have taken actions. Suntech Power's large-scale production of pluto Pluto high-efficiency solar cells has broken the bottleneck of conventional solar cell manufacturing, breaking the world record of crystalline silicon solar cell conversion efficiency, with an efficiency of 17.5 (polysilicon) and 19.5% (monocrystalline silicon); Yingli The use of "panda" technology for the production of high-efficiency single crystal components refreshed the previous efficiency record, the current conversion efficiency has reached 19.89%. Linuo Photovoltaic and IBM technology cooperation also focus on the improvement of conversion efficiency of crystalline silicon cells. Under the application of new technologies, it is expected that the photoelectric conversion efficiency of Linuo photovoltaic cells will be greatly increased on an existing basis.

It is understood that Linuo Solar has also established a talent exchange platform with IBM to learn from each other. At present, the domestic photovoltaic industry faces the problem of scarcity of high-end talents. Almost all PV companies lack a strong R&D team. There are a lot of technical difficulties in the entire PV industry chain that need to be tackled, such as how to make silicon wafers more successful. Thin, more high-purity silicon materials, how to make the conversion efficiency of the battery more than 20%, how to make the life of the components further improve, etc., which all need high-end leader talents. Gao Yuankun, president of Linuo Group, believes: “The development of the photovoltaic industry has entered a stage of scouring the waves. The survival of the fittest will speed up the industry's new round of reshuffling, and the improvement of battery conversion rate will undoubtedly become a magic weapon for enterprises to win. The key to the ultimate survival and development of enterprises is still It is technology, and talent is the first element for achieving technological upgrading and breakthrough, and only by continuously building a world-class technical talent team and R&D team in the photovoltaic field can we truly take the path of an expert.We believe that by working with IBM, Linuo It will quickly grow from an industry chaser to a leader in the industry."

In recent years, based on the steady growth of the Sunshine Economy and Health Industry, Linuo Group seeks a globalized layout by promoting the "fourth five-year" strategy, enhances the position of China's new energy companies in the international arena, and will use MEMC's raw material basis and channel advantages. Through cooperation with IBM to improve its operations management and technological innovation capabilities, it will enable China's solar energy industry to gain more say and promote the success of Chinese manufacturing to China.
