Cadmium telluraide film solar panels.

One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection. Cadmium telluride cdte is the most common type of thin film solar cell in production. On a lifecycle basis cdte pv has the smallest carbon footprint lowest water use and shortest energy payback time of any current photo voltai. 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.

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. Company name region no. An issue with using thin film panels with a cdte is that they contain a large amount of cadmium which is a toxic element. First solar is an american company that works in the cadmium telluride solar panel manufacturing space.

Cigs is another mainstream thin film technology. Copper indium gallium selenide cigs. This structure is similar to the heterojunction in cigs cells. Cadmium is a heavy metal and extremely dangerous.

Thin film solar panels and toxicity cadmium telluride. 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 telluride solar cells use low cost manufacturing technology to produce low cost cells. Cadmium telluride cdte is a commonly used material in thin film solar modules.

As with most thin film solar technologies carrier collection is accomplished by drift or field assisted. This type of substrate is the most used with manufacturing thin film solar panels and holds 50 percent of market share. 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. Cdte thin film panels are made from several thin layers.

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. Companies involved in cdte solar panel production a key thin film panel technology. The debate over the toxic potential of thin film solar panels based on cadmium compounds has been reignited. 25 cdte panel manufacturers are listed below.
