Other than oxides, metal chalcogenides, especially sulfides, form a significant part of the materials which are investigated using the ALD [Riikka, 2005; George, 2010] method. ZnS is the first material that was grown using ALD by employing elemental source of Zn and S [Riikka, 2005]. However, typically H2S is considered as the most efficient reactant because of its higher volatility and chemical reactivity towards most of the metal organic precursors [Riikka, 2005; George, 2010]. To date, a variety of binary metal sulfides including copper sulfide (CuS), bismuth (III) sulfide (Bi2S3), nickel sulfide (NiS), aluminium sulfide (Al2S3), indium sulfide (In2S3), iron sulfide (FeS), SnS, and antimony trisulfide (Sb2S3) are successfully grown using ALD [Riikka, 2005; George, 2010; Neil et al., 2015; Shannon et al., 2017; Elijah et al., 2012]. Multicomponent sulfides such as ternary (copper indium disulfide (CuInS2), chalcostibite (CuSbS2)) and quaternary (copper zinc tin sulfide (Cu2ZnSnS4)) are also deposited for photo absorber materials in solar cells [Neil et al., 2015; Shannon et al., 2017; Elijah et al., 2012]. The self-limiting and complementary deposition chemistry of these materials was confirmed by in-situ quartz crystal microbalance (QCM) and Fourier transform infrared (FTIR) spectroscopy measurements [Neil et al., 2015].

SSPs 1 (M = Cu and Sb) are used to form two different phases of copper antimony sulfide: chalcostibite (CuSbS2) and tetrahedrite (Cu12Sb4S13) [147]. Thin chalcostibite and tetrahedrite films were obtained on mesoporous TiO2 layers (Figure 19(a)). In the first stage, the SSP solution was spin casted onto mesoporous TiO2 films, as a result of which the TiO2 NPs are coated with SSPs. The subsequent thermal treatment leads to metal sulfide sensitized TiO2 films (Figure 19(b–d)).
