World’s shortest laser pulse usage to develop energy efficient solar cell
Switzerland Scientist: world’s shortest laser pulse created by humans to support research and development of solar cells
Switzerland’s Scientists have succeeded in generating the world’s shortest laser pulse with a duration of only 43 attoseconds which is the shortest controlled event that has ever been created by humans.
The researchers from ETH Zurich in Switzerland was made the discovery. now, the development will allow researchers to observe in high detail how electrons move within a molecule or how chemical bonds are formed.
Laser pulse fully understands the dynamics during a chemical reaction, scientists must be able to study all movements of atoms and molecules on their basic time scale. Molecules rotate in the range of picoseconds, their atoms vibrate in the range of femtoseconds, and the electrons move in the range of attoseconds.
The Attosecond spectroscopy could contribute to the development of more efficient solar cells, as for the first time it would be possible to follow the process of excitation through sunlight up to the generation of electricity step by step.
The laser pulse can also be used to alter the course of a chemical reaction, even chemical bonds can be broken by stopping the charge shift at a certain location in the molecule
