Reported are two highly efficient metal‐free perylene dyes featuring N‐annulated thienobenzoperylene (NTBP) and N ‐annulated thienocyclopentaperylene (NTCP), which are coplanar polycyclic aromatic hydrocarbons. Without the use of any coadsorbate, the metal‐free organic dye derived from the NTCP segment was used for a dye‐sensitized solar cell which attained a power conversion efficiency of 12 % under an irradiance of 100 mW cm −2 , simulated air mass global (AM1.5G) sunlight.
