Solar Cell Materials An Overview of Solar Cell Materials

Gallium Arsenide. Gallium arsenide or GaAs is a compound of two elements gallium and arsenic. Gallium is rarer than gold and is a byproduct of the smelting of other metals, particularly aluminum and zinc. Arsenic, on the other hand, is not rare, however it is poisonous.

Amorphous TiO_2 coatings stabilize Si, GaAs, and GaP

Although semiconductors such as silicon (Si), gallium arsenide (GaAs), and gallium phosphide (GaP) have band gaps that make them efficient photoanodes for solar fuel production, these materials are unstable in aqueous media. We show that TiO_2 coatings (4 to 143 nanometers thick) grown by atomic layer deposition prevent corrosion, have electronic defects that promote hole conduction, and are
