Scientists may have made a breakthrough in their quest to produce limitless energy. according to New study Published in the magazine American Chemical SocietyScientists are looking deeper into a molecule known as azulene, a molecule that emits blue light and appears to violate the basic rules of photochemistry.
The hope is that understanding how azulene and other molecules like it convert energy through fluorescence will allow us to build our own molecules to more efficiently convert photons from the sun into usable electricity, thus creating cleaner energy.
The whole idea is part of the natural progression of trying to make solar cells more efficient. If we look at the history of these electricity-generating cells, the first solar cell in 1883 was able to convert less than one percent of the sun’s photons into usable electricity. This was just the first small step towards creating limitless energy.
Now, solar cells have seen some significant upgrades and changes. Although we haven’t reached the point of being able to generate unlimited energy yet, we have solar cells that can convert approximately 50% of the sun’s photons into electricity, and even solar panels that generate electricity in the dark.
Some researchers hope to understand how a molecule like azulene interferes with the idea of photochemistry that we know as the Cacha rule. This rule basically helps explain how molecules emit light when they are in different states. Unlike other molecules, azulene does not appear to follow the Kasha rule.
“It depends on the aromaticity and antiaromaticity of this molecule in different excited states,” said lead author of the study, Thomas Slanina, It was shared in a press release. “We can think of aromaticity as a kind of internal stability of that molecule. When that molecule is aromatic, it’s happy and stable. When it’s antiaromatic, it tries its best to escape from that state somehow.”
As for azulene, it is stable in its ground state, but unstable (antiaromatic) in its first excited state. It’s an interesting discovery that could help lead scientists to make major advances in the search for limitless energy. However, what this unlimited energy will look like is still unclear. For now, at least we have a string to pull.
