A fast, cheap and reliable deposition method was proposed for the one-step preparation of Cu2 - xS layers on F-doped SnO2 within 30 min through an ink-based technique. The electrodes prepared with our method were tested with iodine/iodide electrolyte, Co(II)/(III) bipyridine redox shuttle and Fe(II)/(III) ferrocene-based liquid electrolyte. The Cu2 - xS layers showed high efficiency and stability with the ferrocene/ferrocenium redox couple, showing a fast charge recombination kinetic, low charge transfer resistance (Rct = 0.73 Ω cm2), reasonably high limiting current (11.8 mA cm- 2) and high stability in propylene carbonate.22-28engCopper sulphideCounter-electrodesDye solar cellsFerroceneSemiconductorsSolar energyArtigo10.1016/j.tsf.2016.05.033Acesso aberto2-s2.0-849745751912-s2.0-84974575191.pdf
