In the multitude of semiconductors today, there are only a few which stand out due to their unique properties. Gallium arsenide (GaAs) is one. It is a compound III-V semiconductor made up of gallium (a group V element with an orthorhombic crystal structure) and arsenic (a group III element with a trigonal crystal structure). The unique property that gallium arsenide has is its ability to turn electricity into light. This property allows the semiconductor to be used in an array of applications, ranging from integrated circuits to photovoltaic applications. In this paper, the application of GaAs to solar cell panels is detailed by the author.
