Polysilicon: Take off the "double high" hat

In recent years, China's polysilicon industry has developed rapidly. In 2005, China’s total polysilicon production was 80 tons, which accounted for 0.3% of the world’s total production. In 2011, China’s total polysilicon production reached 65,000 tons, ranking second only to the United States and ranking second in the world. 50% of the domestic market demand. Compared with 2005, China's polysilicon production has expanded 800 times, and the energy consumption per unit of product has dropped by more than 50%.

Has taken off the "double high" hat In the polysilicon industry development process, the domestic enterprises in the "high energy consumption, high pollution, excess production capacity," and other unfavorable factors under pressure, continue to work hard to improve technology, self-improvement, energy efficient reduction The technology, low-temperature hydrogenation technology, exhaust gas dry recovery, and system energy conservation have made major breakthroughs, forming a polysilicon process with Chinese characteristics. Its product technology has reached the world's advanced level, with the ability to compete with the world's old polysilicon companies, providing basic raw material support for China's photovoltaic industry, so that China's photovoltaic industry stands in the world, becoming China's rare industry that can compete with the developed countries in the world.

Calculated at the current industry level, the power consumption of photovoltaic power generation starts from silica and goes into operation of a photovoltaic power generation system. The power consumption is 2.59 kWh/W. When installed under the light conditions in Beijing, it takes only one year or more to power the photovoltaic power generation. Consumption recovers, and in areas with better lighting conditions, the time to recover electricity is shorter. A battery made of polysilicon lasts for 25 or even 40 years, and it can continuously provide clean electricity. Therefore, in the long run, it is a producer of clean energy, not a scapegoat for high energy consumption.

Some media have attributed the high pollution of polysilicon to silicon tetrachloride. Some of its reports have been demonized. In fact, silicon tetrachloride is a by-product of polysilicon production, but at the same time, it is a raw material for polycrystalline silicon. The hydrogenation technology used to hydrogenate it into a trichlorosilane return system, which is the key to reducing the cost of polysilicon, and whether polysilicon companies are willing or have to Investment. For the media, it is recommended that we learn more about the facts of crystal silicon companies, report objectively, maintain their own image, and help the polysilicon industry, and do a better job of blocking foreign industries that have been blocked for decades, and do not rely on foreign media reports.

Key enterprises should support the impact of the debt crisis in Europe, European countries adjust PV subsidy policies, and seek to limit the suppression of Chinese products; the US conducts “double counter” investigations on Chinese PV products, and also to suppress Chinese-made PV power generation products and cause damage to the Chinese PV industry. Great impact. At present, domestic companies are faced with a grim situation of overstocking, oversupply, and production cuts. In order to change this situation, the best way is to accelerate the development of the domestic market, making the world's largest photovoltaic manufacturing country into the largest photovoltaic application country, for the benefit of future generations.

The energy issue is a “hard” crisis. We need to have forward-looking and continuity policies. We need specific supporting policies to address the actual difficulties in the operation process, establish a stable feed-in tariff mechanism, and implement reasonable on-grid tariffs for the entire operation cycle of photovoltaic power plants. The mature experience of the United States, Germany, Japan and other countries has accelerated the implementation of domestic photovoltaic power generation projects. Helping You Strengthen and Build a World-class Polysilicon Production Enterprise, Focusing on the high concentration of polysilicon companies, we will focus on selecting 3 to 5 companies to support and encourage key companies to expand their production capacity, upgrade their technologies, and create world-class polysilicon with real market competitiveness. manufacturer.
