Abstract

In₂S₃ is a promising electron transporting material for solar cells. In this paper, In₂S₃ nanosheet arrays are grown on TiO₂ films by a facile molecular precursor solution method for the first time. The composition, morphology and chemical valance states of the In₂S₃ nanosheet arrays are investigated by XRD, SEM, TEM and XPS techniques. Upon the in situ growth of CuInS₂ nanoparticles into the In₂S₃ nanosheet arrays, the novel CuInS₂ bulk heterojunction solar cells are obtained with a peak power conversion efficiency of 2.58% depending on the In₂S₃ nanosheet array height.
