Selenium exists in several allotropic forms. The most stable, crystalline hexagonal selenium, is metallic gray. Crystalline mono clinic selenium is a deep red color. Amorphous selenium is red in powder form and is black in vitreous form. Gray crystalline 'metallic' selenium conducts electricity better in the light than in the dark (photoconductive) and it can convert light directly into electricity (photovoltaic).
