About Tin
Tin is a metal with atomic number 50 that commonly forms compounds in the +2 and +4 oxidation states. Tin metal is used in solders and protective coatings, while tin dioxide contributes to gas sensors and electronic ceramics. Tin(II) sulfide is a semiconductor investigated as a light absorbing layer in thin film solar cells, where crystal structure, film quality and interfaces influence photovoltaic performance.
