Tin(II) sulfide, by contrast, is formed from cheap, earth abundant elements, and is nontoxic. This material also has a high optical absorption coefficient, p-type conductivity, and a mid range direct band gap of 1.3-1.4 eV, required electronic properties for this type of absorber layer. [ 12 ]
Tin sulfide can refer to either of these chemical compounds: Tin(II) sulfide, SnS; Tin(IV) sulfide, SnS 2 This page was last edited on 2 December ...
Tin(II) sulfide: SnS: 1.3/1.0 [23] direct/indirect: Tin sulfide (SnS) is a semiconductor with direct optical band gap of 1.3 eV and absorption coefficient above 10 4 cm −1 for photon energies above 1.3 eV. It is a p-type semiconductor whose electrical properties can be tailored by doping and structural modification and has emerged as one of ...
ITC supported the price of tin during periods of low prices by buying tin for its buffer stockpile and was able to restrain the price during periods of high prices by selling from the stockpile. This was an anti-free-market approach, designed to assure a sufficient flow of tin to consumer countries and a profit for producer countries.

It also reduces copper(II) to copper(I). Solutions of tin(II) chloride can also serve simply as a source of Sn 2+ ions, which can form other tin(II) compounds via precipitation reactions. For example, reaction with sodium sulfide produces the brown/black tin(II) sulfide: SnCl 2 (aq) + Na 2 S (aq) → SnS (s) + 2 NaCl (aq)
