Solar panels made of gallium arsenide contain a layer of gallium and arsenic that can produce a lot of energy. Because it is rarer than gold, it can be extremely expensive. Its high cost and high risk make it unsuitable for most people, but it is still the best choice for many.
At the 48th IEEE Photovoltaic Specialists Conference, researchers from the Fraunhofer Institute for Solar Energy Systems ISE recently presented how they were able to achieve a record conversion efficiency of 68.9% with a photovoltaic cell under monochromatic laser light.

Gallium Arsenide (GaAs) solar cells. Gallium arsenide (GaAs) is a mixture of two elements, gallium (Ga) and arsenic (As). Gallium is a by-product of the smelting of aluminum and zinc, and is extremely rare. A rare element is certainly not an advantage if we want to bring the energy production of GaAs solar cells to a TW level.
A simple physical model of an isolated solar cell was used to estimate the electrical power generated by 10-Ω-cm Gallium Arsenide/Germanium (GaAs/Ge) solar cells at the Martian surface. This model estimates the short circuit current J sc, the open circuit voltage V oc, and the maximum power per unit area, P m, as functions of …
