Photoelectrochemical characteristics of brush plated tin sulfide thin films

Thin films of tin sulfide find wide applications in optoelectronic devices and window materials for heterojunction solar cells. Thin films of p-SnS were brush plated onto tin oxide coated glass substrates from aqueous solution containing SnCl2 and Na2S2O3. Deposits have been characterized with XRD and SEM for structural analysis. Hot probe method showed invariably p-type nature for all the brush plated SnS films. The variation of space charge capacitance, Csc, with applied potential, V, was recorded for the PEC cell with p-SnS/Fe3+, Fe2+/Pt system. The spectral response of the PEC cell formed with SnS photoelectrode was studied and reported.
