Abstract: We report chemical vapor deposition (CVD) and photoelectrochemical properties of large-area thin films of nano-crystalline SnSe2 on conducting FTO glass. We show that densely packed, randomly oriented SnSe2 nanoflakes can be grown by reacting vapors of tin monoselenide (SnSe) and selenium at 550 °C without compromising the electrical properties of FTO. We demonstrate that SnSe2/FTO is photoelectrochemically active in visible to near-UV wavelengths (350-700 nm) and exhibits incident-photon-to-current-efficiency (IPCE) as high as 3.7% at 0 V versus the Ag/AgCl/1 M KCl reference electrode under 350 nm light illumination. © 2018 The Royal Society of Chemistry.
