Photoelectronic properties of zinc phosphide crystals, films and heterojunctions : quarterly progress report no. 6 for the period July 1 - September 30, 1980 /

The purpose of this research program is to investigate the photoelectronic properties of zinc phosphide (Zn₃P₂ in single crystal form, in thin-film form, and in heterojunctions in which Zn₃P₂ forms one of the elements. This research will be directed toward understanding the role of crystalline defects and impurities in Zn₃P₂, the nature of the electronic charge transport in single crystal and thin-film material, and the properties of photovoltaic heterojunctions involving Zn₃P₂. The scope of the program extends from basic investigations of materials properties on single crystals to the preparation and characterization of all-thin-film heterojunction divices. One of the principal motivations behind this research program is the realization that Zn₃P₂ is a relatively uninvestigated yet ideal component for photovoltaic heterojunction use in solar energy conversion. The proposed program will concentrate on the basic materials problems involved with Zn₃P₂, providing the kind of information needed for other more developmental programs directed toward actual practical cells.

Indium seals /

The feasibility of using indium seals for large vacuum bell jars has been investigated. It is shown that such seals can be made; however, use of this type seal for repetitive operations is not recommended.
