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, arequired electronic properties for this type of absorber layer. [ 12 ]

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.
The name change was unpopular with both the public and employees, and the company was renamed Royal Mail Group plc the following year. [31] Telecom Éireann became eircom in 1999. [32] US West, one of the original 7 Regional Bell Operating Companies, was acquired by Qwest in 2000. [citation needed]
