(OilPrice) A group of scientists from the Queen Mary University of London and the Imperial College London have made quite an amazing discovery: solar cells like pop and rock music, but they're not too keen on classical.
Obviously I am not talking about actual conscious preferences, but rather that by playing high pitched sounds, often found in pop and rock songs, the performance of the solar cells increased remarkably.
In their experiments the researchers grew tiny zinc oxide nanorods and then covered them with an active polymer that created a photovoltaic device to turn the suns light into electricity. The high frequencies and pitches in the songs played caused vibrations in the nanorods which increased the efficiency of the solar cells by 40%.
