Thin films of lead tin sulphide PbSnS2 were deposited on glass substrates at 100 °C at vacuum pressure of 3×10–6 mbar using a thermal evaporation method. Scanning electron microscopy (SEM) and X‐ray characterization revealed that thin films were monophase and polycrystalline. The average particle size was approximately 28 nm. Absorption coefficient of PbSnS2 thin films (∼105 cm–1) was found from transmission optical spectroscopy measurements. Its fundamental absorption edge is shown to be 1.65 eV with direct allowed transition recommended for photovoltaic application. Thermoelectric measurements showed the materials to be p‐type in nature. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…[19] Born and Hellner were the first to determine the crystal structure of boulangerite. [20] Taking into account weak reflections already mentioned by Berry, [15] they concluded that the b and c lattice ARTICLE parameters should be doubled and proposed a = 8.07 Å, b = 42.28 Å, c = 23.46 Å with the tentative space group Cmc2 1 . The primitive setting of this lattice is equivalent to the monoclinic one reported by Robinson (see above).…”

Abstract. In the literature, many seemingly contradictory structure models of boulangerite, ideally Pb 5 Sb 4 S 11 , and the related mineral falkmanite have been reported. These can be explained by a phase transition between a low-temperature (LT) modification (P2 1 /c, a ≈ 8.07 Å, b ≈ 23.5 Å, c ≈ 21.6 Å, β ≈ 100.7°) and a disordered hightemperature (HT) modification [Pnma, a = 23.530(2) Å; b = 4.0385(8) Å and c = 21.273(2) Å, R 1 (obs) = 0.039] that occurs above ca. 350-400°C. The almost completely ordered distribution of lead and antimony cations in the LT modification involves a superstructure; the corresponding reflections are obvious in electron and X-ray diffraction patterns. Partial ordering may render them more or less diffuse. They vanish upon heating above the transition temperature, also for originally ordered natural boulangerite (from Trepča, Kosovo), and appear again after annealing below the phase transition temperature (e.g. at 330°C). The HT phase is characterized by pronounced cation disorder. Cation ordering can be described by group-subgroup relationships which may also serve for a unified description of various structure models from literature. Starting from the orthorhombic HT phase, a

“…The SnSb 4 S 7 compound, being one of semiconducting materials in the sulfosalt family, does not have these disadvantages. It consists of elements, which are abundant in nature [7] low-cost non-toxic materials. SnSb 4 S 7 can be used as an absorbing material in solar cells [8].…”
