A peculiar molecule so blue in color - which "violates [a] well-established law of chemistry” - could hold secrets for boosting solar panel efficiency, reports Popular Mechanics, based on a recent research project from the Czech Republic and Sweden.
The studied the substance, called azulene, sometimes used in medicine and skin care, has long interested scientists because of its unusual fluorescent properties.
The research, led by scientists from the Institute of Organic Chemistry and Biochemistry in Prague, published its work in the Journal of the American Chemical Society in September.
In the report, the molecule team says it “violates" the Kasha rule, which relates to how certain molecules emit light in “excited states.”
The research analyzed how, after azulene reaches an unstable and excited state, it releases its pent-up energy as light (or fluorescing) in a different way from most fluorescent molecules.
In the bigger picture, improving solar power technology helps people harness free energy from the sun to make electricity more safely and without creating toxic pollution that traps heat on the planet.
