Cadmium Telluraide Film Solar Panels

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.

Cadmium telluraide film solar panels.

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

Cadmium is a heavy metal and extremely dangerous. First solar is an american company that works in the cadmium telluride solar panel manufacturing space. Cigs is another mainstream thin film technology. Thin film solar panels and toxicity cadmium telluride.

The debate over the toxic potential of thin film solar panels based on cadmium compounds has been reignited. Company name region no. One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection. This structure is similar to the heterojunction in cigs cells.

Cadmium telluride solar cells use low cost manufacturing technology to produce low cost cells. Companies involved in cdte solar panel production a key thin film panel technology. The most common cdte solar cells consist of a simple p n heterojunction structure containing a p doped cdte layer matched with an n doped cadmium sulfide cds layer which acts as a window layer. Copper indium gallium selenide cigs.

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. The company solyndra now. Cadmium telluride cdte is the most common type of thin film solar cell in production. Cadmium telluride cdte is a stable crystalline compound formed from cadmium and tellurium which is used for manufacturing cdte thin film solar panels in whole lifespan cdte pv has the smallest carbon footprint lowest water use and shortest energy payback time then conventional solar technologies the usage of rare materials may become a limiting factor to the industrial scalability of cdte technology in the mid term future.

Of known sellers power range wp advanced solar power. Cdte thin film panels are made from several thin layers. This type of substrate is the most used with manufacturing thin film solar panels and holds 50 percent of market share. 25 cdte panel manufacturers are listed below.
