Cadmium Telluraide Film Solar Panels

Thin film solar panels and toxicity cadmium telluride.

Cadmium telluraide film solar panels. Cadmium fumes may cause flu like symptoms and more severe respiratory problems. This structure is similar to the heterojunction in cigs cells. An issue with using thin film panels with a cdte is that they contain a large amount of cadmium which is a toxic element. As with most thin film solar technologies carrier collection is accomplished by drift or field assisted.

One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection. Copper indium gallium selenide cigs. Cadmium telluride solar cells use low cost manufacturing technology to produce low cost cells. Of known sellers power range wp advanced solar power.

Cadmium telluride photovoltaics describes a photovoltaic technology that is based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity. The company solyndra now. First solar is an american company that works in the cadmium telluride solar panel manufacturing space. Cdte thin film panels are made from several thin layers.

Solar photovoltaic technology that is based on cadmium is considered as a thin film technology due to its active layers which are just a few microns thick or about a 10 diameter of human hair. Cadmium telluride cdte photovoltaics or also called cadmium telluride solar cell is a kind of photovoltaic pv technology that can produce electricity from sunlight using a thin film of compound cadmium telluride to absorb and convert sunlight into electricity. The debate over the toxic potential of thin film solar panels based on cadmium compounds has been reignited. Cadmium is a heavy metal and extremely dangerous.

Cadmium telluride cdte is the most common type of thin film solar cell in production. Cadmium telluride cdte is a commonly used material in thin film solar modules. Company name region no. Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems.

Companies involved in cdte solar panel production a key thin film panel technology. 25 cdte panel manufacturers are listed below. Cigs is another mainstream thin film technology. On a lifecycle basis cdte pv has the smallest carbon footprint lowest water use and shortest energy payback time of any current photo voltai.
