Semiconductors convert energy from photons into an electron current. However, some photons carry too much energy for the material to absorb. These photons produce 'hot electrons', and the excess energy of these electrons is converted into heat. Materials scientists have been looking for ways to harvest this excess energy. Scientists have now shown that this may be easier than expected.
