Scientists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) are currently working on a joint research project to generate more electricity from solar cells. The scientists also plan to conduct further research on the singlet fission process along with the Argonne-Northwestern Solar Energy Research (ANSER) Center situated United States. Together with Prof. Michael Wasielewski from the ANSER Center, the researchers from FAU have now managed to clarify some extraordinarily significant aspects of Singlet Fission Process.
More Information about the Project
Singlet fission process is actually considered to boost the efficiency of solar cells. This is certainly possible thanks to the latest ongoing research, thus taking it one step closer to achieving such efficiency. The findings have been published in the scientific journal Chem.
With a rise in global energy consumption, the upward trend is set to continue during the upcoming years. In a bid to meet demand while protecting the environment, electricity from the sun’s incident energy, wind, water, and biomass sources is gaining in importance. Speaking about solar cells, they mostly are extremely inefficient at converting solar energy to electricity. In order to improve the efficiency, a way out in the form of implementation of specific physical-chemical processes has been found out. And singlet fission certainly is the method that needs to be learnt and utilized on a large-scale basis. Scientists at FAU and the ANSER Center have been exploring a promising approach as part of their joint research project regarding this method, wherein a single photon excites two electrons.
The working process of the method begins when a photon from sunlight meets and is absorbed by a molecule. This causes the energy level of one of the electrons in the molecule to rise. This is followed by an organic molecule absorbing a photon, consequently giving rise to a state of higher energy. Electricity can then be generated within solar cells from this energy, which is stored temporarily within the molecule.
