Scientists investigate potential of diatomite as a raw material for solar cells

A German-Algerian research team has been investigating ways to produce silicon from diatomite, a fossil material containing amorphous silicon dioxide. The researchers said that, for potential solar cell applications, it will be crucial to extract silion with a low level of impurities. From pv magazine Germany Diatomaceous earth, also known as diatomite, has been used as a material for liquid filters since the 19th century. It is also used in the manufacture of thermal insulation materials, grinding and polishing agents, cleaning agents and insect repellents. The use of this material may be extended ...
