Extensive IMEC improve transformation efficiency solar batteries
IMEC using high-quality large area substrate (70cm2) epitaxial solar batteries have gotten 16.3% conversion efficiency. Previously, low-grade basement area of the battery has received 14.7% conversion efficiency. IMEC has successfully doped in the high degree of quality and low cost base, senior metallurgical grade silicon substrates, obtained only 20 microns thick, high-quality epitaxial silicon stack.
"In the high-quality substrate gained 16.3% of the efficiency and cost efficiency of 14.7% of the basement show that the efficiency of industrial-grade can be achieved through existing technology." IMEC solar energy project director,Jef Poortmans said, "through the use of copper-based access to programs, we can further improve the conversion efficiency, make the low-cost chip-type thin film epitaxial growth of silicon solar batteryies to become a concern of industrial technology. "
P +-type back surface field (BSF), p-type substrate and n-type emitter front formed by the chemical vapor deposition. Battery Light-harvesting methods in the epitaxial / substrate site of the former structure and the internal surface of porous silicon ion Bragg reflector combination has reached the light-harvesting purposes. In the high-quality solar cells used on the copper substrate contact with the program.
Low-quality base metal of solar battery technology using screen printing technology, the diffusion step is the formation of pre-form field and plated silicon nitride antireflection coating manufacturing process after the last step. The epitaxial growth of the equivalent chip substrate can be fully used in the standard industrial solar battery production process.
Sailing: batteries become a major source of income
Sailing share semi-annual report in 2010 commented:
Investment Highlights:
Company realized that the operating income is 1.668 billion yuan, up to 36.43 percent, to achieve operating profit 33.327 million yuan, net profit attributable to shareholders of listed companies is 27.065 million yuan, respectively, an increase are 174.78 percent and 219.74 percent. Company in the first half basic earnings per share is 0.06 yuan, up 200%.
Faster revenue growth, gross profit margin fell slightly
Company in the first half operating income is 1.668 billion yuan, up 36.43 percent, car battery production and sales volume reached 4.83 million, respectively, and 4.94 million, but operating costs increased by 39.17%, slightly higher than revenue, the company's consolidated gross margin was slightly down 0.85 percentage points to 11.37%, of which the battery product gross margin 11.69%, down 1 percentage point. We believe that growth in the first half year performance of the main beneficiaries of substantial growth in car sales, car sales in China were completed during the first half 8,927,300 and 9,016,100, respectively, an increase of 48.84% and 47.67%, but the car is worth noting that in recent months chain sales declined year on year growth rate started to slow down in the second half growth may slow down performance.
Taiwan formed Photovoltaic Innovation Integration Alliance
The "innovation and integration of the photovoltaic industry to promote the Union" was established on the 26th which is promoted by the Taiwan "Ministry of Economic Affairs Industrial Development Bureau and the institute the new green energy , it was understood that the PV industry promotes innovation and integration of the composition of alliance which will integrate " BIPV integration of the League "," CIGS Industry Alliance "," silicon solar battery industry alliance "," DSSC (dye sensitized solar cells) industrial integration of the League "and other industry alliance to construct the PV industry innovation and integration platform upgrade Taiwan's industrial competitiveness.
It is understood that the main reason is to consider, the alliance to Taiwan PV industry still has space vertical integration, in particular, it is lack of integration of solar energy, further integration through the Association of 4 main Unions, in order to enhance Taiwan's industry international competitiveness,it looks forward to using industry alliance platform to assist in the PV industry development needs, mainly to the development of key processes, equipment, materials, components and new applications technologies to establish production cooperation, strategic partnerships, global market position in cooperation such as platform.
Lithium battery stocks fell 1.95%
Lithium stocks is weakness today, after opening all the way down, as of midday close, it downs 1.95%. Stocks are commonly fell, Jiangsu Cathay Pacific fell 5.11%, down 4.96% power sources, in August rose 119% of the integrated CAC rose 4.10%.
Constrained by the market share of foreign patent,the lithium keeps hidden behind the blitz
Lithium companies are hot , because its battery in the new energy vehicles have broad application prospects. However, pure electric car industry has just started in the context of blind speculation, "Lithium" concept does not seem wise. In the industry view, the concept of these lithium-listed companies generally have two shortcomings: first, a considerable number of companies have not mastered the core technology of processing. second, the lithium battery business performance of listed companies on the part of the contribution is very limited.
Chery and Taiwan enterprises to jointly exploit new energy battery market
