Shanghai, People's Daily, December 11 (Reporter Jiang Hong ice), I wonder if you ever thought that one day our clothes, hats, bags can be "self-generation" to the cell phone charge at any time; covers an area of huge power stations will become history, future only need a desk the size of the machine will be able to generate electricity?
recently developed successfully aligned carbon nanotube fibers, has taken a
crucial step to the energy system developed entirely fibrous. Fiber based on
this technology to manufacture a new type of solar batteries, the humanity
anywhere dream efficient use of solar energy is expected to become a reality. Fudan
Advanced Materials Laboratory, Fudan University, Polymer Science Professor Peng Huisheng research group developed this new novel, flexible fibrous energy integrated device can be made into a root hair fine fibrous solar cell, its diameter only 60 to 100 microns (
1 mm = 1000 microns). Fibrous, which means
you can put them like ordinary chemical fiber woven into clothes, pants and
other textiles, clothes, like a large solar panel to achieve their own
"power generation". The new solar fiber battery is able to convert
sunlight into electricity at the same time, these energy saved, no external battery
or energy storage devices. Even in daylight again the photoelectric demand
greater at night, it can also be free to use sunlight energy.
This research has been published the original research of an international chemical authoritative journal in the field of "Applied Chemistry" (Angewandte Chemie International Edition, impact factor 13.5) as the cover article. The reviewer Experts Peng Huisheng research group with a very simple and low-cost method "in the world" for the first time in a fiber photoelectric conversion and energy storage, which greatly improves the efficiency of the use of solar energy, "For full fibrous energy system, a key step."
Traditional solar cell made mostly of monocrystalline silicon, not only higher costs, and its production process is a high energy consumption, high pollution industries, have a significant impact on the environment. Fudan team used carbon nanotubes fiber material may be a good solution to these problems in the future solar cells.
Carbon nanotube fiber is very light and very thin, but the specific strength and specific stiffness than the large-scale use of engineering fibrous materials such as nylon wire, DuPont Kefu La fiber materials (kevlar) strong several times, in the bullet-proof vests, a wide range of areas such as aerospace, medical and sports equipment application prospects. Its process of the solar cell is made basic pollution, high efficiency, low cost, and the production process is also relatively simple, having a large number of stable production possibilities.
