Liu Hanyuan to book to answer the four questions photovoltaic industry
"Excess that" debatable
"Energy Revolution: Change the 21st Century" before publication, for "whether the excess polysilicon industry," said Liu Hanyuan, "Five years ago, China's production of polycrystalline silicon solar cells by more than 99% of imports in 2009, 50% of our own supply of polysilicon, This is a very fast and last year we said excess, and no one thought to rely on last year imported 50% or so 'surplus that' questionable this year, we have 1 / 3 of the polysilicon to rely on imports, that the year after that its good to meet you in such a premise, in the event of financial crisis, I think the intention of government regulation is mainly to remind the possibility of excess, to remind you to pay attention to investment in rhythm. is not only the PV industry, any industry need to pay attention to this problem. "
For polysilicon production of high-energy challenge, Liu Hanyuan said, "If the proper process control center itself does not consume energy, the energy is consumed to maintain the production process as part of the production process consumes energy. Why do we say it is high energy? Because manufacturing process, the polysilicon per kilogram to about 100-200 kWh consumption, high crude look, but we are now doing the result is put into an electricity production of polysilicon, and finally the formation of solar PV modules, which effective life cycle can return 15-20 kWh, up to 20-30 kWh, this unique in the history of human energy consumption. "
Environmental governance is almost zero emissions
For questioned the high pollution industry, Liu Hanyuan said, "This is the concept of the formation of the past and many years ago, people did not master the technology, basically there is no way for recycling, emissions of hydrogen chloride, silicon tetrachloride, and sometimes simply a rushed it, resulting in the pollution emissions, while the new production process, including the mainstream formal manufacturers, it is impossible to see the sky leak, the contamination of the floor, which is a modern business concepts, environmental management is almost done to zero emissions. "
Some people ask, the rise of the domestic film solar cells, polysilicon industry will bring great impact on? Liu Hanyuan confidently said, "We also note that new technologies such as thin-film solar cell research and development and use, but as long as we are a little analysis, from the 1950s satellite into space, to today's International Space Station construction and use for decades, without exception are silicon photovoltaic cells. crystalline silicon solar cell battery as an international mainstream market, especially in the world based on decades of semiconductor silicon materials and technology more sophisticated and mature, it accounted for more than 80% market share, especially grid-connected photovoltaic power generation projects, almost all the good stability, high conversion efficiency of crystalline silicon cells. combined with thin film technology in the technical, environmental impact, especially by the low conversion efficiency of the bottleneck factors, difficult to replace thin-film technology polysilicon in the foreseeable future, the PV industry, polysilicon is still the mainstream and core materials. "
"Obama's Magic" is the core energy revolution
Since 2009, "low-carbon economy" is one of the highest click rate terms. Low-carbon economy is the most important part is to find permanent sustainable development of new energy. According to the International Energy Agency predicts that oil can also be used about 40 years, natural gas can also be used about 50 years, coal can also be used about 120 years. Energy security and food safety has been a threat to human survival.
New energy to become the 21st century "savior" it? Before U.S. President Barack Obama's words in his inaugural speech, "the way we use energy ... ... threatens our planet." Straightforward point to understand the extreme importance of the new energy revolution. Data show that U.S. fiscal year 2009-2010 spending of 3.6 trillion dollars, the deficit reached an unprecedented $ 1.75 trillion. Obama announced the 2013 deficit should be reduced to $ 53.3 million, about 4 years time is to use large-scale reduction in the deficit out of $ 1.217 trillion. By the world known as "Obama's Magic" is the core of 'Energy Deal', the Americans hope that the world economy to achieve wheel drive: use the dollar bill in relying on the wheel, we must also rely on "the amount of energy," the new wheels.
China needs the U.S. to follow up the start button
Currently, the community insight that humanity is facing, "the fourth industrial revolution", and the Industrial Revolution's mission is to create a large number of new and renewable energy. The past, carbon combustion-based industrial model has come to a turning point, must be changed. U.S. energy revolution has started the button, which calls for China but also to keep up with rapidly, in order to accelerate the new energy revolution.
In fact, the Chinese government is actively taking appropriate measures. Vice Premier Li Keqiang has stressed that: "The new energy industry is pregnant with a new economic growth point, is a new round of international competition, the strategic high ground, the current international financial crisis, the energy industry for new opportunities, we should develop new energy sources as important measure to deal with the crisis. to strengthen policy guidance to support and promote wind, solar, biomass development, and promote new energy vehicles, energy efficient buildings and products, widely used to speed up with new energy and energy saving technology to transform traditional industries, as well as promoting energy the adjustment of industrial structure. "
Revitalization of China's new energy industry planning, the Government has the energy to the national strategic level, put into force the boot drive. The future of China, the new energy revolution, the first requirement is that the "new energy" to import, such as wind, hydro, solar, nuclear power and so on. In the new energy plan, the government made a major new energy arrangements will be put up to 3 trillion yuan to promote the development of new energy sources.
