Silicon thin film battery supply crisis led to investment
Since the amorphous silicon thin film was developed, as the laptop battery conversion efficiency is only half of the polysilicon has not been universal. In recent years increasingly favor the photovoltaic industry, triggered a crisis in the supply of silicon materials. Silicon raw material prices, making cell membrane surface again. In 2007, the world’s thin film solar cell output to reach 400MW, over 181MW of 2006 increased 120% market share in 2006 from 8.2% to 12%.
Accordingly, the following components of solar heat, heat polycrystalline silicon, thin film photovoltaic cells and become a new investment hot spot in the field. In June 2008 the German Photovoltaic Exhibition, 2008 with an annual output of Taiwan can only 30MW of green energy, to be signed orders amounted to 200MW, is an annual output of 2008 to 6 times; Yutong energy production yet, have also made orders 60MW. Tianwei change security plans to invest 3.2 billion for the amorphous silicon thin film solar cell projects; Zevi announced in Nanchang, Jiangxi building the world’s most technologically advanced and largest thin film solar cell projects; in July 2008, Johnson & Johnson non-25MW photovoltaic Crystalline silicon thin film solar cell production line officially put into operation Sony battery ; Jiangxi be able to announce the formation of joint stock companies, the goal of building capacity for 50MW of amorphous silicon thin film photovoltaic cell production line. Suntech added, Vosges stake in the new extension to that variety, such as shares of the company have also announced to enter the field of thin film batteries, resulting in the domestic film pa3384u-1brs battery investment.
