A sensitive matter : New sensitizers based on cyclometallated iridium (III) complexes have been studied. Despite poor absorption properties, efficiencies up to 2.5 % were observed. It was seen that poor light‐harvesting properties of the dyes are the main reasons for those efficiencies, which may be improved with better light‐absorbing ligands. Electron‐dynamic investigations show that very fast processes are taking place.
