Is selenium used in solar panels. Working with solar experts from crest durham university the university of oxford and colorado state university fiducia has revealed that selenium works by overcoming the effect of harmful atomic scale defects in cdte panels. This explains the increase of efficiency as electrons subatomic particles that carry electricity which are generated when sunlight hits the solar panel are less likely to be trapped and lost at the defects. However some of the elements used in solar panels are much more harmful. Arsenic cadmium mercury selenium yes the same as above but in higher quantities it s harmful and antimony are all commonly used in their fabrication and they are all classified as pollutants by many countries such as the usa.

Because the material has a high absorption coefficient and strongly absorbs sunlight a much thinner film is required than of other semiconductor materials. Selenium is used in solar cells and photocells in fact the first solar cell was made using selenium.

Silica solar cells. A team at the lawrence berkeley national laboratory in berkeley california embedded selenium in zinc oxide a relatively inexpensive material that could be promising for solar power conversion if. When selenium is added to iron and copper based metals it improves their machinability. The selenium bars used by adams and day and fritts s magic plate did not rely on heat to generate energy as did all other known power devices including solar motors.

It is also used as a photographic toner. Cdte panels have been found to produce electricity at lower costs than. Recently new solar panels have been created that are made from a semiconducting material called cadmium telluride cdte. A copper indium gallium selenide solar cell is a thin film solar cell used to convert sunlight into electric power.

So most dismissed them from the realm of further scientific inquiry. Selenium is used with bismuth in brasses and as an additive to stainless steel.
