AB  - Charge transfer is important for the performance of a photoelectrochemical cell. 
      Understanding photogenerated charge accumulation and separation is mandatory for 
      the design and optimisation of photoelectrochemical cells. Unique stacked and 
      embedded heterostructure of Sb2S3/TiO2 nanotube arrays (NTAs) was fabricated 
      through anodic oxidation with the hydrothermal method. Surface photovoltage 
      spectroscopy, phase spectra and photoluminescence measurements were performed to 
      explore the mechanism by which the inorganic hole transport material CuI affects 
      the charge transfer and photoelectrochemical properties of Sb2S3/TiO2 
      heterostructure NTAs. The interfacial separation and transport of photoinduced 
      charge carriers were also examined by applying current-voltage characteristics 
      (J-V), incident-photon-to-current conversion efficiency (IPCE) and Mott-Schottky 
      techniques. Results show that CuI acts not only as a hole-conducting and 
      electron-blocking material but also as a light-absorbing material in the 
      ultraviolet range. Efficient charge transfer processes exist in CuI/Sb2S3/TiO2 
      heterostructure NTAs. The photoelectrochemical performance of CuI/Sb2S3/TiO2 
      heterostructure NTAs is dramatically improved. Under AM 1.5G illumination at 
      100mW/cm(2), the short-circuit current density and open-circuit voltage are 
      3.51mA/cm(2) and 0.87V, respectively. The photoelectric conversion efficiency of 
      CuI/Sb2S3/TiO2 heterostructure NTAs (0.95%) is 36% higher than that of Sb2S3/TiO2 
      heterostructure NTAs (0.66%).
