Sony announced in November 2010, developed a module area of 4cm × 5cm (area of the openings 17.11cm2), conversion efficiency of 9.9% of the dye-sensitized solar cells (DSC). March 2008 a single module conversion efficiency of 7.5% in April 2009 was 8.4% in May 2010 was 9.5%, this was 10%. Earlier reports had said that if the dye-sensitized solar cell is less than a few mm square area of “small unit “, can reach 12.3% conversion efficiency, but a few cm square module conversion efficiency reached 9.9%, anywhere in the world Top level. Sony’s small units conversion efficiency of 11.0%.

As the key to improved performance, Sony cited the independent development of the “synergy effect ” technology. The technology used in combination with the wavelength of light absorption and the absorption rate of 2 different colors. Aims to improve the light absorption efficiency, expand the range of wavelengths available.

The battery with the use of different colors to form solar cells in series structure is the difference between the two pigments mixed use. Although other research groups had also tried, but “will occur in the electronic exchange between pigment, does not help to improve efficiency”(Sony, Environment and Energy Division developed the core components of business development power system components, including Minister of Development, Kazuhiro Noda). Sony said, by improving the color combination of the molecular structure of titanium dioxide (TiO2) part, addresses this issue.

Sony previously said, “The goal is to block the practical efficiency of 10%. ” Basically, the 9.9% reached this goal. In addition, Sony also developed that can enhance the durability of the gel electrolyte, and can replace the high cost of platinum (Pt) electrode carbon electrode. Can be said that Sony from achieving “power window ” target home appliances and power generation is a step closer.

It is understood that the battery manufacturers in China, Guangdong accounted for 70% market share, BYD as a new energy vehicles and battery manufacturer, has become the first breakthrough in the industry, enterprise, together with Guangzhou Honda, FAW-Volkswagen and other auto makers, Guangdong in the development of new energy automotive industry, the doubt can be a demonstration of the specimens.

For the new energy automotive industry, most industry insiders believe the current battery, motor, electric control and the vehicle is the most critical aspects of business, but often overlooked after the battery end of life how to handle the problem. In fact, the only real solution to the problem after the battery end of life, new energy vehicles in order to achieve real and industrial chain.

Bump Nickel Cobalt Technology Co., Ltd. Foshan Nanhai is a local company specializing in waste battery recycling business, the company director Yu Haijun told reporters that the current production of an electric vehicle, batteries accounted for half the cost. Directed cycle split of used batteries, not only solve the problem of environmental pollution, but also to achieve the reuse of resources, and promote the sustainable development of the industry.

It is reported that the country, including mobile phone batteries, laptop batteries and other small battery production value of about 100 billion stars of these small cells per 200 grams; and new energy vehicles in the battery weight is generally 200 kg to 400 kg, according to this ratio terms, the new energy vehicles in the real market-oriented operation, the battery recycling industry will reach 3,000 billion per year to 500 billion yuan of output value.

Huge market cake, with used batteries in the new energy automotive industry chain, the importance of making more and more attention began to be betting that this is not known industry.

At the recent meeting of high pay, Party Secretary Wang Yang Bump circulation technology used in cell cycle power demonstration center to stay for 10 minutes. “It was very unexpected find, secretary Wang Yang, Guangdong Province, have made the original battery recycling waste recycling business.” Yu Haijun, said Wang Yang, secretary at that time encouraged the enterprises, hoping to become the Pearl River Delta and the whole Bump Guangdong Province, supporting the electric vehicle industry enterprise, Bump technology cycle have this foundation, it has the expertise.

Recently, the State officially announced in the next five years will invest 10 trillion yuan or 1.5 trillion dollars, the development of strategic new industries, new energy vehicles, including a seat on its feet.

In recent years, become a global pursuit of new energy vehicles, the development of the “new darling.” In this circumstance, the associated batteries, charging stations, motors, electronic control and other industries, has become the most investment potential of the industry. However, the most closely watched in the battery industry, but there is a lot of environmental problems: the new energy gradually fiery electric vehicles, will generate a lot of battery, after reaching the retirement period, these batteries do?

In fact, battery scrap and if it did not get a reasonable decomposition, will be serious environmental pollution problems, such as can be qualitatively decomposition cycle, you can achieve energy recycling. How environmentally friendly processing of waste batteries, as well as recycling, energy will undoubtedly become a new electric car industry supply chain can not be the missing link.
