Abstract

Iodide redox (3I -/I 3 -), polysulfide redox (S 2-/S x 2-), organic redox [TMTU/TMFDS 2+: tetramethylthiourea/tetramethylformaminium- bis(trifluoromethanesulfonyl)imide], ferrocene redox (Fc/Fc +), nickel redox [Ni(ii)/Ni(iii)], and cobalt redox [Co(ii)/Co(iii)] hole conducting electrolytes were systematically investigated to determine their suitability for use in Sb 2S 3-sensitized photoelectrochemical solar cells. A long-term stability test and UV-visible spectral analyses revealed that Sb 2S 3-sensitized photoelectrochemical solar cells worked stably with Co(ii)(o-phen) 3(TFSI) 2/Co(iii)(o-phen) 3(TFSI) 3 [TFSI: bis(trifluoromethanesulfonyl)imide] as the redox mediator.
