Cadnium Solar Panels

Cadmium telluride cdte is the most common type of thin film solar cell in production.

Cadnium 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. This lack of weight gain occurred at low moderate and high doses. Cdte thin film panels are made from several thin layers. Copper indium gallium selenide cigs.

Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems. Cigs is another mainstream thin film technology. Cadmium telluride ct is a highly toxic chemical that is part of solar panels. On a lifecycle basis cdte pv has the smallest carbon footprint lowest water use and shortest energy payback time of any current photo voltai.

Production 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. They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel. The debate over the toxic potential of thin film solar panels based on cadmium compounds has been reignited. Cadmium telluride cdte is a commonly used material in thin film solar modules.

Cadmium fumes may cause flu like symptoms and more severe respiratory problems. Cadmium telluride solar cells use low cost manufacturing technology to produce low cost cells. Thin film solar panels and toxicity cadmium telluride. One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection.

The company solyndra now. Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants. 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. In the journal progress in photovoltaics it reported that male and female rats that received ct through ingestion did not gain weight as they normally should have.

Cadmium telluride cdte thin films are made of cadmium which is a toxic expensive cancer causing heavy metal. Cadmium is a heavy metal and extremely dangerous. Worse rainwater can wash many of these toxics out of the fragments of solar modules over time. As the second most common photovoltaic technology on the market behind traditional crystalline silicon cadmium telluride cdte panels are already a viable thin film solar panel solution.
