In this article, we are reporting the effect of different substrates on the growth of nanostructured bismuth selenide (Bi 2 Se 3 ) thin films for photoelectrochemical (PEC) application. Three different substrates are used such as glass, indium doped tin oxide (ITO) and fluorine doped tin oxide (FTO) for the deposition of Bi 2 Se 3 thin film using arrested precipitation technique at room temperature (300 K). The optical, structural, morphological, compositional and PEC properties of Bi 2 Se 3 thin films were studied by using various characterization techniques such as UV–Vis–NIR, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy and PEC as a function of different substrates. Finally, the PEC performance of deposited thin films shows highest conversion efficiency 0.14 % for Bi 2 Se 3 thin films deposited on FTO coated substrate surface.
