Got a light? The importance of the relationship between the charge recombination and charge transfer during photocurrent generation through DNA films is described. The photocurrent efficiency for DNA films, in which the charge‐transfer and recombination rates were modulated by changing the sequence, was investigated by using the photoelectrochemical measurements on an Au electrode.
