A curious study by scientists at Queen Mary University of London and Imperial College London has found that the music that inspires so many of us may exercise too also makes solar panels work better.
The high frequencies and pitch found in pop and rock music cause vibrations that enhanced energy generation in solar cells containing a cluster of 'nanorods', leading to a 40 per cent increase in efficiency of the solar cells.
Let’s not forget that we have been told before to sing or talk to plants, maybe future advice for the maintenance of solar panels is to do the same.
Sounds as low as road-side traffic could improve the efficiency of solar cells, according to the study.
"We thought the sound waves, which produce random fluctuations, would cancel each other out and so didn't expect to see any significant overall effect on the power output," said James Durrant, Professor of Photochemistry at Imperial College London, who co-led the study.
The study’s results are as much a surprise to him then it is incredible to us.
"We tried playing music instead of dull flat sounds, as this helped us explore the effect of different pitches. The biggest difference we found was when we played pop music rather than classical, which we now realize is because our acoustic solar cells respond best to the higher pitched sounds present in pop music," he concluded.
