Light down a wire for solar power
Image via Wikipedia
Solar power could be produced cheaply in specially designed optical fibres, say researchers.
The work, published in the journal Angewandte Chemie, makes use of nanometre-scale wires built around optical fibres like bristles.
Those wires give the light much more surface area to interact with, leading to higher overall efficiencies.
However, only the ends of the fibres [...]
