Japan has developed the world's highest conversion rate of the next generation of solar cells

Science University of Tokyo, Japan, Arakawa-yu and Laptop Battery UK is a professor at a research team led the successful development of a few days ago had been referred to as "dye-sensitized type" next-generation solar cells, this thinkpad battery to power the light efficiency as high as 11% of the world the highest level.

"Japanese Economic News" published an article on the 29th, said "-type dye-sensitized" solar cells are used in materials and titanium dioxide pigment. To enhance the photoelectric conversion efficiency, the researchers will be to control the size of titanium dioxide nano-scale, so that pigment can absorb light more effectively. Although the test products, only 5 mm in length and width, but will strive to achieve large-scale, reaching 10 cm.

Science University of Tokyo Arakawa, Professor Yu said: "If you change the type of pigment, there may be a higher conversion efficiency." Solar cells with silicon, the new solar cell is expected to lower the price.

Lead-acid battery industry in China to implement the production permit system

In order to effectively curb the blind lead-acid battery industry to develop and standardize the market competition, promoting the healthy development of enterprises and improve industry-wide management and product quality, lead-acid battery industry in China to implement the production permit system. Those with inadequate facilities, backward technology, polluting enterprises are not eligible to obtain production licenses, and their products are not allowed to enter the market.

Lead-acid ThinkPad R50 Battery, ThinkPad R50e Battery industry in China after 50 years of construction and development, has been basically formed a combination of small, medium and large enterprises with certain scale manufacturing system, the last century since the 80's reform and opening-up, lead-acid battery industry has been the rapid development of products and grade and level markedly improved for the national economic development has contributed to the power demand to achieve a home-made batteries, saving a large amount of foreign exchange. Entered the "Ninth Five-Year Plan", as China's reform and opening up further to develop in depth, energy, transportation and communications industries, such as the rapid development of the lead-acid battery industry has brought about tremendous opportunities for development, the demand for lead-acid batteries in China every year 15% ~ 40% of the rate of growth in output for more than 30 million years KW.H more rapidly on the rise. At the same time, due to profit-driven and local protection reasons, the expansion of a battery development company, from dozens of the original development of the current 2,000. The production of lead-acid battery is a hazardous operation, necessary in the strict environmental protection measures and industrial safety and hygiene conditions of production, or the operator and the ecological environment will cause harm. Lead-acid battery industry as a result of barriers to entry relatively low, relatively simple processes and technology, resulting in the current range battery manufacturers, smaller, more polluting, the situation of uneven quality. In view of this, ready to implement the production permit system.

Lead-acid battery production, said the permit system is a simple production license, without a permit does not allow the production and marketing of products. Battery industry production licenses in accordance with the State Administration of Quality Supervision, Inspection and Quarantine Order No. 19 "industrial products production license management practices" carried out.

Bid process for the production license, an application submitted at the same time a copy of enterprise business license, the application of self-report battery type. Following a review in line with the battery information on the permit conditions and complete declaration, the admissibility of a notice issued, after the Group of Experts on-site examination arrangements and on-site sampling, on-site review and testing all the standard battery, after the approval of the permit are authorized to award production.

Site review focused on the hardware facilities of the ThinkPad R51 Battery, ThinkPad R52 Battery production, environmental protection facilities, means testing, battery testing is in accordance with national standards or industry standards for testing of batteries.
