Zinc Phosphide Applications

Zinc Phosphide (CAS 1314-84-7) is an ideal candidate for thin-film photovoltaic applications, for it has strong optical absorption and an almost ideal bandgap (1.5eV). In addition to this, both zinc and phosphorus are found abundantly in the earth’s crust, meaning that material extraction cost is low compared with that of other thin-film photovoltaics. Both zinc and phosphorus are also nontoxic, which is not the case for other common commercial thin-film photovoltaics, like cadmium telluride.

Metal phosphides have been used as rodenticides. A mixture of food and zinc phosphide is left where the rodents can eat it. Zinc Phosphide is typically added to rodent baits in the amount of around 0.75-2%. Such baits have a strong, pungent garlic-like odor characteristic of phosphine liberated by hydrolysis.
