Biggest names in the domestic photovoltaic thin-film battery prospects retrial
Since the fourth quarter of last year's strong recovery this week in Shanghai at the "Sixth China solar grade silicon and PV Power Conference" has become a successful major photovoltaic manufacturers to get rid of the financial crisis a "celebration party." At the meeting, the domestic solar photovoltaic gurus of the future full of confidence, especially for thin-film battery prospects for a re-evaluation.
Prior to the industry view was that, as polysilicon prices collapsed, thin-film battery competitiveness will decline, and even some scholars believe that the cost of thin-film batteries with silicon no advantage at all, may be between 3 to 5 years in China disappeared. In this regard, a number of photovoltaic industry yesterday to be refuted.
Ministry of Industry and Information Technology Electronics and Information Wang Bo, deputy director, said in a report yesterday, the current domestic companies more than 60 thin-film batteries, although the proportion is still high, but as a representative of the new technology, the energy conversion efficiency is gradually improved, and its production costs are lower, the proportion expected in the future will be increasingly high, and in the future to play its own advantages.
Zhejiang University, Professor Yang Deren also revealed that Japan held the "2010 NEDO Conference", the community also discussed how to thin film batteries to a more efficient and cost-direction and other issues.
Semi china analyst Song in Beijing, said countries are to increase solar energy technology development, and hope our government can be established as soon as China's own Solar Energy Research Institute, and enhancing our thin-film batteries, or other new technology research and development capabilities, accelerating the pace of solar grid parity .
"Although, with the crystalline silicon products, prices, thin film cells differentiated competitive advantage has been weakened, but the company remains devoted to its great energy, and is gradually enhance their competitiveness. The future will show a new look to all walks of life . "Zhejiang Chint Solar Energy Technology Co., Ltd. General Manager YANGLI said.
Baoding Tianwei Ma, general manager of thin-film photovoltaic thin film cells on the same literature, the future development of confidence, "thin-film battery technologies is still in its infancy, much room for technological advances, the cost can fall, we should be emerging products to give sufficient confidence. "
New GM hydrogen fuel cell system will be put into operation in 2015
March 16, General Motors, said GM is currently testing the new hydrogen fuel cell system, and the battery system will be put into operation in 2015.
GM said the new research and development of hydrogen fuel cell system is the size of the Chevrolet Equinox fuel cell vehicle equipped with half the weight of 220 pounds, only one-third of the fuel cell Equinox.
GM spokesman Alan Adler said in an interview, the new hydrogen fuel cells because the volume is small, so it can carry a variety of models, such as cars and crossover vehicles, even in the compact car can carry.
But Alan Adler did not disclose the new hydrogen fuel cell production in 2015, will be used in the Which models.
Currently, GM's Chevrolet Equinox hydrogen fuel cell vehicles are in the testing phase.
Recently, GM's global powertrain chief executive, said Charles Freese, GM will not give up hydrogen car plans.
Compound semiconductor multi-junction solar cells will be mass production
U.S. Weixun joint semiconductor (RFMicroDevices, RFMD) to use the company's 150mm GaAs compound semiconductor production line, trial out of the solar cell. RFMD said it is the conversion efficiency of more than 40% of the "compound semiconductor multi-junction solar cell to achieve commercialization milestone."
The release of RFMD and the U.S. Department of Energy's research, "National Renewable Energy Laboratory (NREL)" to jointly promote the development of compound semiconductor solar cell project's initial results. RFMD does not change the existing compound semiconductor devices that constitute the production line, but the direct use.
RFMD plans in the future through the following two stages, first in 2012, junction solar cell more than the amount of production. First, confirm that the use of NREL's IP (InterlectualProperty) solar cell production line at RFMD's manufacturing. Second, in RFMD's 150mm production line to verify that the solar cell volume production yield and manufacturing costs.
