Last year in October, Japan, Showa Shell Oil hit a copper indium selenide thin-film photovoltaic conversion efficiency of solar cells the highest world record. Area of 864 square centimeters of the conversion efficiency of 14.3%, an area of 3560 square centimeters of the conversion efficiency of 13.4%. As the company has made use of the solar cell Japan’s first 10-kilowatt solar power system, so that the practical application of solar cells a major step forward.

Copper indium selenide thin film solar cells can be realized cost-efficient, with less than the current mainstream because of its crystalline Si solar cells the cost of the Department of competitive advantage, is expected as a next-generation solar cells. In addition, copper indium selenide thin film solar cell tolerance to the cosmic rays than other batteries is high, a low-cost, light weight of the universe, solar cells, can be used as satellite power supplies.

Reduce the production cost is the Dell Latitude D430 Battery key to the promotion of solar cells. German Solar Energy Research Institute after 10 years of hard work, developed a new type of thin-film solar cell technology, the technology uses a continuous electro-deposition process, the copper foil was prepared to form thin-film solar cells with a volume, and then a special assembly packaging process into the soft solar modules. At present, this battery has reached 9.2% efficiency in laboratory and theoretical efficiency of up to 30%, and because less material consumption, simple process, the final cost is expected to be lower than 0.6 euros per watt.

Thin-film solar cells involved in the automotive industry with Dell Laptop battery

Japan’s third-largest car maker Honda Motor Co. announced last December 19, from 2007 started mass production of solar cells, the company will Kyushu Kumamoto factory cars again in the establishment of a factory specializing in the production of solar cells, Once the new plant production capacity to achieve the desired 27.5 megawatts, enough to meet 8000’s daily electricity needs of the family, then a year from the sale of solar cells to obtain 70 million U.S. dollars in revenue.

Although Honda has not publicly produced the materials used in solar cells, but industry insiders believe are using does not contain silicon, copper indium selenide (CIS) thin film, such solar cells from the early 20th century, 80 developed in polycrystalline thin-film Dell Latitude D500 Battery. CIS cell with its low-cost, high efficiency monocrystalline silicon solar cells close to the stability and strong anti-radiation of the space to become this century’s most promising solar cells is one of the many research institutions at home and abroad and industry experts hotspot. And made of silicon as the raw material compared to conventional solar cells, copper indium selenide thin films in the production process of the energy consumed is only half of the latter, but also a corresponding reduction in carbon dioxide emissions by 50%.

China’s rapid development

China’s independently developed the “copper indium selenide thin film solar cell test platform with the pilot line” project, has been of Science and Technology as a national “863″ plan a new research topic.

Nokia fires in India

According to Sony Battery Indian media reports, Nokia announced the global recall of 46 million mobile phone batteries just three days later, a Nokia N70 cell phone last night, fire incidents occurred in India, but fortunately no injuries.

At 9:25 am, India’s Punjab province, a pharmacist Swiss map Kaka (Ritu Kakar) of the N70 mobile phone at home, suddenly caught fire, Kaka’s son, Connaught Han said: “The mobile phone I was not around when the fire broke out, despite the mobile phone shell intact, but the internal distributed out of a wave Jiaohu Wei. ”

Connaught Han said he learned the news of Nokia’s battery recall has opened mobile phone to check the battery whether the recall of the column, but because the sony vgp-bps2 battery on a 26-bit identification code blurred, he had to go to Nokia service center for help However, the staff has been refused. Novo-han’s father, said: “We feel very lucky that nobody was injured, but Nokia should be held accountable.”

Beijing August 14, Nokia announced the global recall of 46 million mobile phone batteries, these models as “BL-5C” batteries from Matsushita in December 2005 to November 2006 production, in very few cases, “BL-5C” battery charging may be due to short circuit and overheat, and cause the battery to dislodge. At present the company has received 100 cases of overheating in the global report, but so far there were no injuries were reported. “BL-5C” battery is Nokia’s most widely used battery, Panasonic and other vendors for a total of three Nokia produced more than 300 million. The fire broke out in India’s N70 mobile phone also used “BL-5C” batteries.

Nokia announced a recall of batteries in the news, consumers are lining up all over India to replace the battery. In Howrah (Howrah) to a Nokia cell phone repair center, 250 line to replace the battery and dissatisfaction of consumers queuing up a lot of shopkeepers have taken place in the number of disputes, which is regarded as the situation out of control sony vgp-bps2a battery, chaos finally brought under control.

Environmental vulnerability problem in China’s battery industry

As the multinational investment in China and international market demand increasing, China’s annual growth rate of lead-acid batteries for more than 30% or more to become the world’s largest exporters of batteries. However, environmental issues continues to hamper the development of the industry.

For a variety of reasons, the battery production process of the pollution problem has not been well resolved, especially the large number of medium and small enterprises serious pollution problem in the production process, producers are numerous small scale, are more polluting, quality varies, some do not have the environmental conditions of the workshop-style factories rush into mass action, about 1 / 4 of the enterprise without the environmental approvals unauthorized site construction, pollution control facilities are not complete, the production is not strict environmental protection measures and industrial safety and health under conditions of the operator and the sony vgp-bps2b battery ecological environment hazards.

Production permit system does not strictly clean production, environmental protection facilities in compliance to this juncture. Although our country since 2005, implement the production permit system, but because of the approval and implementation, there are some problems and did not really encourage manufacturers to achieve cleaner production, many manufacturers are not compliance to legalizing, causing serious environmental problems.

Laws related to environmental protection there are still many imperfect and not wholly satisfactory. Against polluting enterprises, environmental protection and the amount of fines and other departments is limited, companies can not compare the social costs of pollution.

China is actively pursuing the circular economy, 90% of the waste batteries can be recycled, but China’s industrial policy is not to waste battery recycling a good development space, resulted in their becoming long-term problem in China’s battery development bottleneck.

At present, China is not a lead-acid sony vgp-bps2c battery recycling waste management, legal norms, the country did not establish a professional waste lead-acid battery recycling companies, non-business or a professional Secondary Lead battery recycling enterprises to establish a national network and regional recycling networks, work is scattered throughout the recovery operation and disorderly state, the recovery rate of waste lead-acid batteries is not high.

Experts suggest that to increase the proportion of new products, develop sound and resource-conserving products, focusing on the development of sealed maintenance-free lead-acid batteries, the phasing out of open-type batteries. Accelerate the technological transformation, the use of advanced process equipment and effective control of the production process of the environmental pollution problems, to achieve cleaner production. And encourages the colloidal lead-acid batteries, winding bipolar lead-acid batteries and other new types of sony VGP-BPL2 battery research and development, improve the utilization of lead.
