CdTe cells: First Solar’s CdTe thin-film batteries for the world’s leading conversion efficiency of about 10% of its battery production, driven by thin-film cell production in 2007 reached 400MW, the growth rate of 120%. In 2007, the company’s cost of batteries was 1.23 U.S. dollars / watt than the compaq laptop battery industry average is 50% below the price at about 2.4 U.S. dollars / watt. Plans by the end of 2009 production capacity can reach 1000MW. In 2008 a quarter, the company’s main revenue grew 194.1 percent and gross margins of 53%. As the Cd as toxic metals, CdTe cell facing the problem of waste recycling, its large-scale affected to some degree, their future is bound to influence the pattern of PV industry is limited.
CIS cells: copper, indium, tin compounds produced by a thin-film battery, conversion efficiency of 11% or so (the most recent U.S. Department of Energy’s laboratory CIS cell conversion efficiency of up to 19.9%). Because of the different accessories, there is CIGS, CISCuT different categories. As the CIS both high optical efficiency and low cost of materials has two advantages, we are optimistic about their future long-term growth potential. The indium (In) are rare, and will be binding factor in the overall size of the industry. armada m700 battery , evo n400c battery.
The thin-film batteries they use a glass substrate, installation and transportation costs are relatively high. To include GlobalSolar, Nanosolar, Odersun and other companies are now able to produce metal-based substrates collapsible flexible CIS cells, in terms of cost, product efficacy, all aspects of capacity are currently at a relatively leading trend. In particular, Nanosolar has been to reduce the cost to 0.99 U.S. dollars / watt, or about the current average price of 3.74 U.S. dollars thin-film battery module / W 1 / 4. Nanosolar and other companies to expand thin-film batteries will have a huge impact on the price. evo n410c battery , evo n600c battery.
