Indium and gallium are elements of the periodic table while arsenic is a element. Alloys made of these chemical groups are referred to as "III-V" compounds.

Indium gallium arsenideWikipedia

Gallium arsenide (GaAs) is an important semiconductor material for high-cost, high-efficiency solar cells and is used for single-crystalline thin film solar cells and for multi-junction solar cells. The first known operational use of GaAs solar cells in space was for the Venera 3 mission, launched in 1965.
