BYD Longgang iron battery production project
Concerns of the industry projects BYD iron battery production in the Longgang District! Reporter recently learned, BYD Company Limited to be in Longgang Baolong Industrial Zone to build a large iron battery project, which brought at least 6.0 billion of annual output value ; settled in the project, while Baolong Industrial Zone, BYD will Baolong Industrial Zone in the construction of a landmark Baolong.
Head of Longgang District, said recently in an investigation, the original iron battery production base in Huizhou BYD small-scale production, "but given the global interest in customer-iron battery, so the decision on BYD Baolong Industrial Zone, Shenzhen mass production, this is more conducive to international markets. "
Recently, Longgang District secretary Jiang Zunyu to BYD Company Limited research, preparing for BYD Company Limited Baolong Industrial Zone, construction of large projects welcomed iron battery, and as soon as possible promote the settlement of land issues, "Longgang scarce land resources have been very, very rare, but large-scale iron battery for BYD's high-tech projects such we very much support. Meanwhile, we hope iron battery project must be of high standard, high quality and enhance the image of the Baolong Industrial Zone . related public facilities, built according to the planning needs of the Government to implement as soon as possible and solve the industrial area staff dining, leisure and consumption demand. the construction of industrial zones, should the standards to build a new city. "
According to reports, BYD to 100% for 3 consecutive years of high growth to become a cutting-edge national attention at home and abroad own car brands. BYD iron battery Baolong Industrial Zone project in production, the next step will be a strategic project for electric vehicles and energy storage power station --- basis.
Ultimate solar cell (3): full use of a wide range of wavelengths of light
To be able to handle a wide range of wavelengths and multi-junction thin-film phase composition, the industry has begun to be used as electrodes for the development of transparent conductive film can handle a wide range of wavelengths of the material. The main advantage of the existing thin film solar cells visible light (400 ~ 700nm), but in order to improve efficiency, while also using infrared light region. At this time, if the use of existing ITO (Indium Tin Oxide, ITO), light transmittance infrared region will be reduced, and to improve the transmission rate, resistance will rise. Therefore, the need to develop in the 2000nm long wavelength side also has a high transmittance and low resistance of the new transparent conductive film.
As a wide range of wavelengths with high transmission rates, low resistance materials, and is optimistic about the Fuji Electric Holdings began developing graphene (Graphene). Characterized by the migration rate of 10,000 5000cm2/Vs, than the ITO of 20 ~ 50cm2/Vs high three digits. Thus, even if the surface resistance is set to the same with the ITO 10Ω/sq, can also be formed on a wide range of wavelengths with a high transmittance of the film.
Fuji Electric Holdings to form a coating method using graphene film. Graphite coated with material from the low-cost manufacturing. Will be made of layered graphite oxide and graphite oxide after the formation of methanol in the graphene strip. And, by extracting only a single layer coating liquid graphene oxide, and restore to 1000 °C, can form a fine overlapping graphene graphene film.
To control the light through the photonic crystal
In the light control of solar cells, photonic crystals experts also gave a great concern. Noda, Kyoto University research team into the photonic crystals by a variety of methods on the application in solar cells was studied. For example, wild Tianjie Shao, using three-dimensional photonic crystal, "Preparation of solar cells by carrier recombination can not exist when the light generated by the crystal, can prevent the carrier recombination."
Three-dimensional structure formed before the method is more complicated and can Noda developed a simple method of forming the structure. The method used in the thickness direction on the opening hole aluminum ramp mask, etching of silicon. Because the mask can be tilted to form an ion along the track, and therefore can be inclined holes on the silicon etching. Mask rotated by 180 degrees and then etching, was well able to form a stripe-shaped accumulation of three-dimensional photonic crystal structure. Has been successfully processed to 0.8µm pitch out of the deepest reaches of the diamond structure of silicon to 2.2 cycles of stripes structure. The research team said that if we can shorten the interval to 2 / 3, will prevent the solar cells in the carrier recombination.
