, scientists are looking deeper at a molecule known as azulene, which is a blue-light emitting molecule that seems to flout the fundamental rules of photochemistry.Privacy Notice.
The idea is all part of the normal progression to try to make solar cells more efficient. Looking back at the history of these electricity-generating cells, the first solar cell in 1883 could convert less than one percent of the Sun’s photons to usable electricity. That was just the first baby step towards creating limitless energy, though.Now, solar cells have seen some significant upgrades and changes.
“It’s based on the aromaticity and the antiaromaticity of that molecule in different excited states,” lead author of the study, Tomáš Slanina,. “We can think of aromaticity as a kind of internal stabilization of that molecule. When that molecule is aromatic, it’s happy, it’s stable. When it’s antiaromatic, it’s trying its best to escape that state somehow.”
