Zinc phosphide (Zn3P2) is an inorganic chemical compound. It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide. Zn3P2 is an II-V semiconductor with a direct bandgap of 1.5 eV and may have applications in photovoltaic cells. A second compound exists in the zinc-phosphorus system, zinc diphosphide (ZnP2).

Applications

Zinc phosphide is an ideal candidate for thin-film photovoltaic applications, for it has strong optical absorption and an almost ideal band gap (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.

Researchers at the University of Alberta were the first to successfully synthesize colloidal zinc phosphide. Before this, researchers were able to create efficient solar cells from bulk zinc phosphide, but their fabrication required temperatures greater than 850 °C or complicated vacuum deposition methods. By contrast, colloidal zinc phosphide nanoparticles, contained in a zinc phosphide “ink”, allows for inexpensive, easy large-scale production, by means of a slot-die coating or spray coating.
