In recent years, the photovoltaic industry has become the world's economy one of the hottest. Solar photovoltaic system as the core, with the climax of the rise of industrial investment, it is natural that the development ushered in the spring. According to the consultant for the latest release of "2009-2012 China Solar Photovoltaic Industry Analysis and Forecast of Investment Report" shows that more than 130 world countries into wider application of the upsurge of solar cells, of which more than 90 countries is being carried out large-scale research and development of solar cells, the active production of new products related to energy conservation. 2007 global solar cell production reached 3436MW, over 56 percent growth in 2006, 2008 global solar cell production up to 6850MW, growth rate of nearly 100%.
Solar cells based on different materials, solar cells can be divided into: silicon solar cells, multi-compounds, such as thin-film solar cells. Among them, the silicon solar cell is the most mature development, in the dominant applications. However, as in the past few years, the international spot price of polysilicon soaring, once in 2005 from the 35 U.S. dollars / kg up to 2008 of 480 U.S. dollars / kg, so the low price of thin-film batteries have been developed rapidly.
The industry has been estimated that within the next few years if the thin-film battery materials in the conversion rate and the demand for non-technical aspects of a breakthrough, it will soon be submerged in the sea of silicon cells.
Thin-film batteries for another bad news is that the international spot prices of silicon raw materials are still down, the U.S. companies such as Dow Corning has announced that the future price of polysilicon in the 40-50 dollar / kg more reasonable. Polysilicon raw materials in such a price, the price of crystalline silicon cells are close to thin-film batteries, thin film batteries, low-cost survival "trump card" no longer exists, the prospects will be extremely bleak.
It was also very optimistic about the prospects for thin-film batteries. Latest world's largest thin-film silicon solar cells photovoltaic Xinao said, "This is not to say more than 10% conversion rate on the more competitive, but in different application fields the question of who is more advantage. Thin-film and crystalline silicon applications are different, the conversion efficiency of crystalline silicon high, the use of small size, with the roof edge is. But from the perspective of customers, they are most concerned about price or system, such as the construction of large-scale power plant, the thin-film battery more There are advantages, because the area, the system price will be low. In addition, building integrated photovoltaic doing so, thin-film batteries have a better advantage. "
Leading global manufacturer of thin-film solar market trends to expand, it seems to give the industry confidence greatly. For consultants in the research department of the energy industry data show that in 2008 reached an annual production capacity of 503MW, in one fell swoop into the second position of the industry, the U.S. thin-film solar maker First Solar did not stop the pace of expansion, in 2009 the company wants to double production capacity to significantly 1GW, and this figure is expected to surpass Germany's Q-Cells, a new industry leader. First Solar's expansion was so rapid pace, with the cost advantages are inseparable. 2008 No. 4 of the First Solar-quarter average cost of production has been reduced to 0.98 U.S. dollars per watt, is the world's first production cost is lower than 1 U.S. dollars per watt of solar energy companies.
Consultant in the energy industry analyst for that the future of thin-film laptop battery, in the end is ashes in fetal life or die? Currently not final word, no one can predict the future of technology breakthroughs to what extent, it can not jump to conclusions. However, it can be predicted that the global PV market size, and not with the crystalline silicon thin-film "Game" and the growth rate slowed down to the solar photovoltaic industry to represent the future will still be the bright spot in the global investment.
