The Fudan University R & D manufacturing solar fiber battery of new materials（3）

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.

In addition to the aligned carbon nanotube fibers successfully used in the manufacture of solar panel, recently, the research group of Professor Peng successfully to this fiber material as the electrode, and the development of a new type of linear micro supercapacitor and lithium-ion battery, and its achievements international materials authoritative journal in the field of advanced materials "(Advanced Materials, impact factor 13.9) also published in the form of a cover story. They use the fibrous material of carbon nanotubes to manufacture a series of high-efficiency linear dye-sensitized solar cell and a polymer solar cell and having a good flexibility and can be woven, the highest photoelectric conversion efficiency of more than 9%; also successful using the same fiber The materials to build a miniature linear super capacitor. Latest photoelectric conversion and energy storage in one fibrous solar cell R & D and linear lithium-ion battery, the relevant performance indicators have been further improved, and has laid a good foundation for the large-scale application of the linear energy devices.
