| Abstract: | 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. |
