Abstract: In this paper, we successfully fabricated a novel heterojunction composite film composed of 1,4-bis(ferrocene)thiophene and SnO2 nanoparticles. The morphology and microstructure have been investigated by AFM and XRD. Their Optical and photovoltage properties were also studied using UV-Vis spectra and surface photovoltage spectra (SPS). The results indicate that the novel heterojunction composite film has a higher photovoltage response in a wider region of 300～550 nm than the single film.

Key words: Surface photovoltage spectra (SPS), Heterojunction, 1,4-bis(ferrocene)thiophene, SnO2 nanoparticles
