Researchers have succeeded in demonstrating superabsorption in a device – a possible cornerstone for quantum batteries.
can be set . Its functionality is based on the process of supe absorption, the ability of a molecule to absorb light.
This process has so far only been successful in theory and still had to be demonstrated on a correspondingly large scale in order to build quantum batteries. As New Atlas reports , scientists have now put this quantum mechanical principle into practice and as part of a study in a proof of Concept Device
detected.
“Superabsorption is a collective quantum effect in which transitions between the states of the molecules interfere constructively”, explained James Quach
, Corresponding Author the study. “Constructive interference occurs in all types of waves (light, sound, waves on water) and occurs when add different waves to achieve a greater effect than each wave alone combined molecules can absorb light more efficiently than if each molecule were acting individually.”
The more energy-storing molecules there are, the more efficiently they can absorb that energy, ergo the
the battery is, the more quickly it will be charged.Function and construction
For the test device, the researchers used a dye called Lumogen-F Orange
, acting as an active layer of light-absorbing molecules, in a microcavity between 2 mirrors. According to Quach, they were produced using a standard method for making high-quality mirrors. “This involves alternating layers of dielectric materials – silicon dioxide and niobium pentoxide – used to specify a so-called “distributed Bragg Reflector“. This creates mirrors that reflect much more light than a typical metal or Glass mirror. This is important so that the light stays in the cavity as long as possible.
Transient absorption spectroscopy was then used to measure how the dye molecules store the energy and how quickly it does so entire device is charged.The result proved the super-absorption because as the size of the microcavity and the number of molecules increased, the charging time decreased.
A Great Beginning
“The idea is a proof of principle for having a ve “The greater absorption of light is possible in such a device,” Quach explained. “But the biggest challenge is bridging the gap between proving principle for a small device and exploiting the same ideas in larger, usable devices.” This research is still at the beginning , however, this success could be a cornerstone for the use of quantum batteries.
These could be faster-charging electric vehicles or energy storage systems in the future A reality that can handle energy peaks from renewable sources. “The next steps are to explore how this can be combined with other energy storage and transmission options to create a device that is practically usable,” said Quach.
