A light switch : A nanocrystalline hybrid photoelectrode consisting of nitrogen‐modified titanium dioxide (an n‐type semiconductor) and copper(I) iodide (a p‐type semiconductor) on conducting glass shows wavelength‐controlled switching of the photocurrent in the narrow range from 410 to 420 nm (see picture).
