Photo-electrochemical water splitting system with three-layer n-type organic semiconductor film as photoanode under visible irradiation

A three-layer structure of n-type organic semiconductors （PTCDA/PTCDA：PCBM/PCBM） is successfully identified as pho- toanode for photoelectrochemical water oxidation during the overall splitting of water into hydrogen/oxygen in a nearly stoi- chiometric ratio （H2：O2 = 2：1） under visible irradiation （...

Zusammenfassung:A three-layer structure of n-type organic semiconductors （PTCDA/PTCDA：PCBM/PCBM） is successfully identified as pho- toanode for photoelectrochemical water oxidation during the overall splitting of water into hydrogen/oxygen in a nearly stoi- chiometric ratio （H2：O2 = 2：1） under visible irradiation （2 〉 420 nm）. A possible charge separation mechanism under visible light illumination was also proposed.
