摘要： The hybrid junctions were fabricated on the ITO glass by combining the hydrothermal method grown zinc oxide nanorods (ZnO NRs) with spin coated P3HT (poly-3-hexyl-thiophene) films. Surface photovoltage technique using Kelvin probe and lock-in amplifier was utilized to study the photo-generated charges at surface and interface of as-grown inorganic-organic hybrid junctions. The results illustrated that the SPS (surface photovoltage spectroscopy) response intensity was significantly enhanced and response range was expanded due to the incorporation of P3HT in ZnO NRs/P3HT hybrid junctions. Moreover, it was inferred that the P3HT could reduce the surface photo-generated charges and shorten the relaxation time of recombination process in the ZnO NRs/P3HT structure, which would be favorable for the photovoltaic applications of ZnO NRs/P3HT bulk hybrid junctions.
