Thin-film solar cells gradually spread

Apollo Solar Energy (00566) resume trading yesterday, shares surged more than 3 percent was the highest seen 0.91 yuan, mainly because the company announced that, with mainland Chinese private clean energy companies signed a sales contract can be controlled, can sell to the Chinese total 2.55 billion U.S. dollars (about HK $ 19.8 billion) in thin-film solar module production equipment. In addition, HK $ 1.17 billion Chinese will be able to subscribe Apollo Solar Energy about 49 million shares, representing Apollo has 51.5% of the enlarged share capital. In other words, in addition to Apollo Hina major customers, will be the majority shareholder.

Apollo was formerly engaged in the toy business, RBI, in October last year 4.18 billion acquisition of a company engaged in manufacturing thin-film solar PV module production line of specialized equipment and the company's 80% interest, which involved transformation of solar energy business, its main business for PV module manufacturers to provide equipment and production lines, so can be considered in the upstream industry.

In fact, want to talk about today is the thin-film solar cells, solar power system has three types of cells, including crystalline silicon, thin film and concentrator, which is the mainstream crystalline silicon, such as silicon and polysilicon. Zengyin polysilicon shortage, the price was pushed up to 500 U.S. dollars / kg, now dropped to about 50 U.S. dollars / kg.

Although solar energy is considered clean energy, but the polysilicon refining process is energy-intensive and high pollution. Thin-film solar cells is the principle of a layer of thin film solar cells, silicon is extremely rare, or do not use silicon, so more to reduce production costs and reduce pollution.

In fact, thin-film solar cells available for some time, but because of the low photoelectric conversion efficiency than silicon, so I did not spread, but as technology advances, photovoltaic conversion efficiency has been improved over 2 years ago by 30% to 40%. According to statistics, in 2005 all the solar thin-film solar cells, battery capacity in only 5% last year, its share has more than 20%. Thin-film solar cells becoming more popular, will limit growth in demand for polysilicon.

Wang Lianbang: China's lithium battery technology and advanced technology, the main gap

Battery electric vehicles as the heart, the performance of the car plays a decisive role. Lithium-ion batteries, lead acid batteries, fuel cells ... These cells differ? Performance between them is? To this end, we specifically sought the advice of Zhejiang University Professor of Chemical Engineering and Materials Science, Dr. Wang Lianbang.

Professor Wang has 15 years of battery research qualifications, studied in Japan, the main lithium-ion batteries, fuel cells and other new power technologies. In recent years, Professor Wang has been working with leading enterprises in Zhejiang Province, the battery, such as Zhejiang and other day to have a close working group to develop lithium-ion battery and solar powered hybrid cars.

Professor Wang told reporters that the launch of the car prices of pure electric vehicles, lithium-ion batteries used mainly as a vehicle power. Currently, lithium-ion battery carbon cathode materials are generally used, but there are four kinds of cathode materials, namely lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate and ternary materials. Lithium cobalt oxide and carbon materials with a lithium-ion is mainly used in mobile phones, lithium manganese oxide and ternary materials made of carbon materials with lithium-ion batteries used in electric tools, only the lithium iron phosphate and a combination of carbon materials Lithium-ion battery was used in the car, also known as lithium-iron battery or iron battery.

As the lithium iron phosphate is expensive, plus technical and manufacturing difficulties, power lithium-ion batteries of higher prices, led to the current high price of electric vehicles. He told reporters that the lithium-ion batteries for high production requirements, it particularly sensitive to humidity, it must be with good equipment and plant conditions and high-skilled workers in order to produce qualified lithium-ion battery. China's current lithium-ion battery technology gap with the advanced foreign technology primarily lies in the quality of raw materials, equipment, the gap between the quality of skilled workers. Therefore, from this perspective, not a lot of money to invest in equipment and quality raw materials business, can not produce quality and reliable power lithium-ion battery.

Lead-acid battery is currently used in battery electric bicycle. Professor Wang as "particularly strong vitality" to describe the lead-acid batteries. He told reporters that the lead-acid batteries as early as 150 years ago, invented, and while we think it almost has to be eliminated, but thanks to the development of China's electric bicycle industry, it received a "second youth." Zhejiang Changxing is the largest producer of lead-acid batteries, accounting for more than 43% of the national production.

Lead-acid battery has the advantage of cheap, the same power of the battery, which costs only one-third of lithium-ion battery to one-fifth; can be large current discharge, "float" performance, is often used as the car battery ; there is uninterrupted power supply for the telecommunications industry or reserve power supply. Its disadvantage is pollution of manufacture large, low energy density, heavy weight, short-lived, and the battery inside the active material utilization is low, generally only about 35%.

First use of pure biofuel flight test aircraft completed

8 in Berlin - Brandenburg International Aviation and Aerospace Exhibition, the European civil aircraft manufacturer Airbus (Airbus) to complete the international coalition led by the world's first use of pure biofuel flight test.

June 8, "a new generation of Diamond DA42" aircraft with 100% of algae biofuels, took part in the flying display. This is the first demonstration of bio-fuel technologies can supply energy for the aircraft. The success of this test confirms keen to develop bio-fuel efforts of engineers, and encourage them to conduct further research to reduce aircraft adverse effects on the environment.

Airbus owner EADS (EADS), said a specific type of algae oil can be extracted with higher levels of this algae bio-fuels made from conventional jet fuel than the energy provided by a higher, but also in the more marginal lands or waters contaminated growth.

Air quality measurements showed that the traditional oil extraction compared to emissions generated by kerosene, algae biofuel emissions of hydrocarbons contained in the eight times less. Airbus also said that the algae biofuel produced by nitrogen oxides to 40% less sulfur dioxide generated even less, this is because, compared with fossil fuels, bio-materials have been included in the composition of nitrogen and sulfur content on much less.

Seaweed is now seen as the most promising source of biofuel, because compared with other biofuel sources, such as Jatropha or Camelina spp, algae need to grow up less space. In the past two years, airlines have been tested three bio-fuels, including Air New Zealand, KLM Royal Dutch Airlines and Japan Airlines, but they are in the test of these bio-fuels and jet fuel mix used .

Berlin - Brandenburg International Aviation and Aerospace Exhibition on display in Berlin, Germany, from 8 until 13.

Life, the body is said to have opened scrapped BYD F3DM low carbon version of the battery are also available. But some people used to know.

Teach you to identify good or bad charger

Market, the so-called universal fast charge, voltage 4 ~ 6V, current 0 ~ 700MA. Strong charging voltage high-current fast pace of course, but too easily lead to the battery current from the drum to shorten life, but high current will have a great heat, the temperature is too high is easy to cause the battery to explode, this is the most serious security risks. 2 years ago there have been several since the summer temperature is too high, resulting in cell phone battery explosion injured person's news, we are interested can look around, security is really not a joking matter. From this we can conclude that: charger is not charging faster, the better.

Since the explosion of the battery temperature is too high and the news, many manufacturers have made changes in power output, increased the pressure limiting current limiting resistor, this voltage and current are under control, the temperature is not high, but the voltage is too low , the battery can not be filled, with a half-day one day one charge no electricity, or now charge a high capacity battery has fully satisfied for 1-2 days, after a long time to reduce battery capacity and affect life. Recommend the use of big brand manufacturers such as chargers, through land and sea, flying hair back and so on. Recently the market has out a new universal charge, Bo Tao, Hiromi Department of brands, listening to people say that if manufacturers in Shenzhen Bognis technology, the factory in Sakata. Bo Tao of the three light charger and the charger I bought colorful tested, electrical properties are very good, in the standard range, and flying hair back, land and sea through the neck and neck and other major brands. Cattle do drop more, 1 m 5 times, completely OK, a little shell rupture, 2 meters or 5 times no big problem. Still down from the fourth floor, the shells are rotten, basically in a naked state, and Jianhui Lai power a test, actually electrical properties without any problems, carefully looked at the electronic components and solder joints, really solid material. Ordinary universal charge and do not to mention still falling, and a little spot on the fall off, the machine will not work. The only regret, Bo Tao colorful appearance actually an old-fashioned egg-shaped, very beautiful, looking forward to the future it will be more beautiful appearance. Price than the flying hair back, land and sea through cheaper, cost is very high, it is recommended to try next.
