Photosensitivity of the structures based on quinary solid solutions of the isoelectronic series of germanium

The temperature dependence of resistivity and the spectrum of optical absorption are investigated for (Cu2GaSe3)0.6(3GaAs)0.4 single crystals. Photosensitive structures of several types (Schottky barriers, welded structures, and photoelectrochemical cells) have been developed. The rectification and the photovoltaic effect are observed for the structures obtained. The revealed specific features of photosensitivity in structures and possibilities for their practical application as photoconverters are also discussed.
