Suitably designed symmetric dyes can be used in dye‐sensitized solar cells to reduce the charge recombination rate by two to three orders of magnitude. If the electron coupling between the electrode and the dye is mediated by a conjugated linker, it is possible to design dyes for which the HOMO of the dye is not coupled to the semiconductor.
