The most used semiconductor materials are silicon, germanium, and gallium arsenide. Of the three, germanium was one of the earliest semiconductor materials used. Germanium has four valence electrons, which are electrons located on the outer shell of the atom. The number of valence electrons in a semiconductor material determines its conductivity.

Transportation costs were assumed to be $700/kg for launch to LEO and $11,50O/kg for launch to GEO (1); volume and packaging constraints were not con- sidered in the transportation costs. The AM0 effi- ciency of the silicon arrays was assumed to be 147.
