China Drying Internet News wonders if you ever thought that the clothes worn on your body, hats worn on your head, and bags in your hands can “self-generate†to charge your “moribund†mobile phone. Can you imagine that the large-scale power station now will only need a table-sized machine to generate electricity in the future? With the advent of a new energy device oriented carbon nanotube fiber, all this will become possible.
News from the press conference recently held at Fudan University: The research team of Prof. Peng Huisheng of the Advanced Materials Laboratory and Polymer Science of the university recently successfully developed a new type of energy device, oriented carbon nanotube fiber, based on this technology. The new type of solar fiber battery makes it possible for human beings to use solar energy efficiently anytime and anywhere.
The new, flexible fibrous energy integrated device newly developed by Professor Peng Huisheng's team can produce a fibrous solar cell that is as thin as a hair filament, and its diameter is only 60 to 100 microns. Fibrous means that they can be woven into clothes, trousers and other textiles as ordinary chemical fibers, as a whole piece of large solar cells can be worn on the body, and to achieve their own power generation.
Miraculously, unlike existing solar cells, this new type of solar fiber cell converts sunlight into electricity while also storing it, without the need for external batteries or energy storage devices. In this way, even at night, people can use the solar energy stored during the day as they wish.
It is reported that the relevant research results have been published as the cover article in the latest edition of the authoritative journal "Applied Chemistry" in the field of international chemical originality research. Reviewers believe that Peng Huisheng’s research group uses a “very simple and low-cost method†to “achieve photoelectric conversion and energy storage on a single fiber for the first time†worldwide, which greatly improves the efficiency of solar energy utilization.†A key step has been taken for a full-fibre energy system."
Traditional solar cells are mostly made of single crystal silicon, which not only has a high cost but also has a high energy consumption and high pollution in the production process, which has a great impact on the environment. The carbon nanotube fibers used by the Fudan team may well solve these problems in future solar cells.
Carbon nanotube fibers have a diameter comparable to that of hair and can be up to several hundred meters in length. The biggest feature is lightness and strength. A ballpoint pen can be easily lifted using a carbon nanotube fiber with a diameter of only 20-30 microns. "If the diameter is 5mm, it can lift a 2-ton car." The staff said that carbon nanotube fibers have already shown important application prospects in a wide range of fields such as body armor, aerospace, medical and sports equipment. The process of making carbon nanofibers into solar cells is basically non-polluting, has high efficiency, low cost, relatively simple manufacturing process, and has a large number of stable production possibilities.
Professor Peng said that they completed the source research work in the laboratory and may have opened up new directions, but the development of applied research and process preparation techniques for these new concepts and new technologies requires the cooperation of a large number of researchers. Perhaps we can imagine that one day in the future, super-solar generators and super batteries made from new fibers will become indispensable partners for ordinary people's lives, providing a steady flow of clean electricity to human society.
