Cadnium Solar Panels

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.

Cadnium solar panels.

Cadmium telluride solar cells use low cost manufacturing technology to produce low cost cells. Cadmium telluride cdte thin films are made of cadmium which is a toxic expensive cancer causing heavy metal. Solar panels often contain lead cadmium and other toxic chemicals that cannot be removed without breaking apart the entire panel. Cadmium fumes may cause flu like symptoms and more severe respiratory problems.

This lack of weight gain occurred at low moderate and high doses. 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. One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection.

They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel. Cadmium is a heavy metal and extremely dangerous. Copper indium gallium selenide cigs. Cigs is another mainstream thin film technology.

Worse rainwater can wash many of these toxics out of the fragments of solar modules over time. The company solyndra now. Thin film solar panels and toxicity cadmium telluride. Cadmium can be rinsed into the water table during the production process.

Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems. Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants. Cdte thin film panels are made from several thin layers. 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.

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. On a lifecycle basis cdte pv has the smallest carbon footprint lowest water use and shortest energy payback time of any current photo voltai. The debate over the toxic potential of thin film solar panels based on cadmium compounds has been reignited. 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.
