Cadmium Telluraide Film Solar Panels

Companies involved in cdte solar panel production a key thin film panel technology.

Cadmium telluraide film solar panels.

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. Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems. The company solyndra now. This type of substrate is the most used with manufacturing thin film solar panels and holds 50 percent of market share.

This structure is similar to the heterojunction in cigs cells. One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection. Cigs is another mainstream thin film technology. 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 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. 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 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.

Of known sellers power range wp advanced solar power. As with most thin film solar technologies carrier collection is accomplished by drift or field assisted. 25 cdte panel manufacturers are listed below. Cadmium fumes may cause flu like symptoms and more severe respiratory problems.

The debate over the toxic potential of thin film solar panels based on cadmium compounds has been reignited. Company name region no. Cadmium telluride solar cells use low cost manufacturing technology to produce low cost cells. Copper indium gallium selenide cigs.

Cadmium is a heavy metal and extremely dangerous. Thin film solar panels and toxicity cadmium telluride. 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. Cdte thin film panels are made from several thin layers.
