The first piece 15 inches graphene transparent electrodes were successfully

    "The difficulty is equivalent to a standard football capped with a thin layer of plastic wrap, to do it completely smooth and intact, requires a high degree of scientific and precise process control level" in the interpretation of high quality to be prepared uniform single-layer graphene, and successfully complete transfer to the difficulty of flexible PET substrate and the other flat on the substrate surface, the deputy director of the Chinese Academy of Sciences, Chongqing Institute of Micro-Nano manufacturing and  grid tie inverter system integration Research Center Shihao Fei metaphor.

    It is understood that, so far prepared graphene main micro mechanical peeling method, SiC pyrolysis epitaxial growth method, chemical vapor deposition (CVD), chemical oxidation-reduction method and the like. Which, the most promising is the CVD method, the method requires first graphene catalyzed the growth of the metal surface, and then transferred to a different substrate, but at 1000 ℃, and therefore not suitable for large-scale chemical production applications, nor conducive to energy conservation and environmental protection.

    Shi Haofei introduced the hospital "graphene transparent electrodes key technology" research, by expanding traditional CVD graphene methods, the proposed industrial raw materials economy and easy access as an effective carbon source, such as plastic (PMMA and polystyrene) and liquid benzene achieve the graphene growth of high quality at a low temperature of 300 degrees Celsius, and controllable growth of the graphene layers can be achieved to some extent. Hospital graphene prepared with respect to the current market leading the transparent conductive film ITO transparent electrode transmittance higher and reached 97.1%, large area, the defect is small, the use of smooth, lower power consumption, more stable performance, the overall thinner and lighter, the cost is much lower than the ITO, is expected to lead the touch screen, flexible displays, solar panel and other related fields revolution.

Anhui electricity accepting the first distributed photovoltaic electricity 

January 24, Hefei power supply company received the first distributed PV power grid projects. Hefei is the process and time frame of 13 "the first batch of concentrated photovoltaic power inverter  generation demonstration zone", Anhui Electric Power Company active service distributed photovoltaic power grid, has opened a "green channel", a clear grid. Implementation of business process "a foreign" by the large client manager tracking service, to provide project owners and network for the process description, the scene, access solutions, and network acceptance Progress query set of services.
