Detailed Description

Tellurium’s primary use is for manufacturing films essential to photovoltaic solar cells. When alloyed with other elements— such as cadmium—tellurium forms a compound that exhibits enhanced electrical conductivity. Therefore, a thin film can efficiently absorb sunlight and convert it into electricity. Tellurium is one of the least common elements on Earth. Most rocks contain an average of about 3 parts per billion tellurium, making it rarer than the rare earth elements and eight times less abundant than gold. Image credit: USGS.
