Research conducted by British and American scientists has found that allowing electrons in organic solar cells to “spin†in a specific way is expected to substantially increase the photoelectric conversion efficiency of organic solar cells. This latest technology can also be used to develop higher performance organic light-emitting diodes. Organic solar cells mimic the photosynthesis of plants. They are thin, lightweight, and flexible. They can also be printed like newspapers. Compared with silicon-based solar cells, which are widely used today, the manufacturing process is faster and the cost is lower. However, its highest photoelectric conversion rate is only 12%, and it is not comparable to silicon-based solar cells with conversion efficiencies as high as 20% to 25% and thus more commercial advantages. Now, studies conducted by scientists from Cambridge University and the University of Washington have found that manipulating the spin modes of electrons in organic solar cells can significantly improve their performance and help scientists develop inexpensive and high-performance organic solar energy. battery. Previously, scientists were puzzled by the different performance of the electrons in organic solar cells. They hoped to clarify why some electronic performances would be unexpectedly good, while other electronic ones performed poorly. To this end, scientists at the Cavendish Laboratory at Cambridge University have developed a sensitive laser technology to track the behavior and interaction of electrons in organic solar cells. They were surprised to find that the "culprit" is the quantum property of electron-owned spin. Spin is a property owned by a particle that is related to its angular momentum. Electrons have two ways of spinning: up or down. Through a process called "recombination," the electrons in a solar cell lose their energy and enter a completely empty state called "hole." Researchers have discovered that allowing electrons to "spin" in a specific way can prevent energy loss and increase solar cell currents. The leader of the study, Akshay Raoao, a researcher at Cavendish Laboratories, said: "Thanks to this exciting study, we can use spin physics to improve the performance of solar cells. Previously, we It is thought that this cannot happen. New materials and solar cells developed using this method may soon be available." The researchers believe that this design concept helps scientists to reduce the difference in conversion efficiency between organic solar cells and silicon-based solar cells, and it is also expected to be used to manufacture higher-performance organic light-emitting diodes. Organic light-emitting diodes are an emerging display technology for making more efficient displays used in mobile phones and televisions. Here are all MAKITA power tools and the designated carbon brushes,motor brushes, electric brushes, motor brushes, electric motor brushes or simply brushes.

For each power tool, there are usually two carbon brushes to choose from: With automatic stop and without automatic stop. Carbon brushes with automatic stop have a spring through the length of the carbon brush. When the carbon brush wears out, the spring gets released, the current to the carbon brush gets interrupted and your power tools switches off at once. The advantage: No additional wear and tear to your power tool. Carbon brushes without automatic stop do not stop functioning at once, but performance of your power tool will detoriate rapidly. Although handy as a warning sign, this usually isn't very beneficial to your power tool.
