(International) U.S. solar photovoltaic conversion rate hit a new record

December 6 Xinhua released by the U.S. Department of Energy on the 6th that the United States an organization to produce solar cells created a photoelectric conversion efficiency of 40.7% of the new record.

Such solar cells by the Boeing - Spectroscopy Laboratory of manufacture, its solar panels using different semiconductor materials, the interface of various materials have formed a special thin layer. Such a structure will enable solar panels “inclusive” in a larger spectral range. Compared with ordinary solar cells, the new battery can “seize” the sun for more kinds of wavelength photons, so that photoelectric conversion rate of 40.7%, and the present widespread use of solar photovoltaic conversion rate was only 13% to 22%.

U.S. Department of Energy believes that the outcome of the research and development has taken an important step, as a basis is expected to eventually developed the ideal solar cells. It is estimated that a 1-watt installation cost of this battery is only 3 U.S. dollars, generating cost of 8-10 cents per kWh. This solar cell will be extremely competitive.

U.S. media said the fuel cell vehicles significantly more environmentally friendly, auto show debut

Beijing held a grand Motor Show. In this exhibition, a total of from more than 20 different countries participated in hundreds of new models on display, including several of the latest fuel cell concept car. The concept of environment protection and energy has already begun at this Beijing auto show further demonstrated.

Energy and environmental protection is an international automotive technology is currently the biggest problem. In this context, hydrogen fuel cell technology has become the focus of the major auto giants compete. In addition, as a transitional technology, hybrid, bio-energy powered vehicles have also been displayed on the Beijing auto show. Chevrolet Sequel hydrogen fuel cell vehicles has been described as General Motors of the most cutting-edge technology, but also the world’s most advanced technology. According to president of General Motors said the company will launch 100 units in 2008 car Sequel. Because it can not be considered a true sense of mass production, so this model run and did not give the actual pricing. But once you start a large-scale mass production stage, this fuel cell vehicles in the price will remain a considerable competitive advantage situation.

Wang Chuanfu: 37-year-old riches legend

Was originally a penniless farm children, 26-year-old when they become a senior engineer, associate professor; in just seven years, nickel-cadmium battery production and sales will be the world’s first, second nickel-metal hydride batteries, lithium batteries ranked third, 37-year-old has become well known around the world, “king of mobile phone batteries”, sitting on 338 million U.S. dollars of wealth; in 2003, he spent a lot triumph and the automotive industry, vowing to become the auto magnate … … he is the Chairman of the Board BYD Company Limited Chief Executive Officer Wang Chuanfu. What is the success of the myth of his youth entrepreneurship has become the business Wizards it? Many people think the answer is wisdom, refined and sweat, and he himself believed that “the most crucial thing is to have spirit of adventure.”

Craziness: Battery king-made cars

If we say that it alone in terms of entrepreneurship is the first time for Wang Chuanfu adventure, then the decision to manufacture car is undoubtedly his adventure craziness. January 23, 2003, BYD announced that the price at 2.7 billion acquisition of Xian Qin Chuan Auto Co., Ltd. 77% of the shares. Geely, BYD, after becoming the country’s second privately-owned car manufacturers.

August 2003, in Shaanxi and Guangdong to promote trade and economic cooperation conference, Wang Chuanfu Zaibao surprise move, BYD and Xi’an High-tech Industry Development Zone, Shaanxi Provincial Investment Group signed a joint venture contract BYD electric vehicle production line, the project investment of 2 billion yuan.

Wang Chuanfu idea is that by battery production areas of core technology strengths, build electric vehicles in China and the world’s No. 1 brand, “Battery king” will build cars with their combination of long items. Wang Chuanfu self-confidence comes from BYD in battery production’s success. He wanted to copy such a success, he spotted a huge car for the city of Chang Wang Chuanfu BYD made cars to find a good reason. First of all, three years later, the battery manufacturer BYD will reach its peak, the need to find other industries to expand. Second, relative to state-owned enterprises, the BYD has institutional advantages. Domestic private car market, more than 60% annual growth in the great room will be full of temptations.

“I do a car on the rest of my life.” Wang Chuanfu said.

In January 2004, Shenzhen has 200 BYD-made lithium-ion electric cars into rental operations, became the first electric car demonstration area, truly zero-emission exhaust. This electric vehicles on a single charge after driving 350 km, the cost price in 10 million to 12 million the retail price of 14 million. Have finished the necessary improvements, will fully enter the Beijing market, and in Shanghai, Guangzhou, Xi’an and other cities listed.

In 2006, BYD electric cars to be officially began commercial operations. And in Wang Chuanfu the “plate” also have such a plan ready: BYD Holdings Qinchuan The main purpose of the acquisition of a small car enterprises, to develop electric vehicle batteries, want an electric car as a stake in the domestic manufacturing, and The company has developed electric vehicles with rechargeable batteries. It is reported that BYD Auto R & D departments are Qingli design and planning, 1.3 to 3.0 displacement displacement of Eight series of car development program. BYD Auto to build in the main plant is located in Xi’an Hi-tech Development Zone, combined with the existing car production lines to reform. At the same time, BYD was established in Shanghai, “BYD Auto R & D center.” Soon, BYD Auto will reach an annual output capacity of 300,000 cars, becoming another major car production base in China.

While planning for Wang Chuanfu interlocking looks, but many believe that the charge is far from the car industry, the difficulty of the current technical condition can imagine, Wang Chuanfu the repairer is a crazy dream is no doubt a dangerous move. In this connection, with a background in engineering master’s mind should have a spectrum Wang Chuanfu.
