Cadnium Solar Panels

Cigs is another mainstream thin film technology.

Cadnium solar panels.

Solar panels often contain lead cadmium and other toxic chemicals that cannot be removed without breaking apart the entire panel. Cadmium is a heavy metal and extremely dangerous. Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems. Cadmium telluride cdte thin films are made of cadmium which is a toxic expensive cancer causing heavy metal.

The debate over the toxic potential of thin film solar panels based on cadmium compounds has been reignited. 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. They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel.

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 is the most common type of thin film solar cell in production. Copper indium gallium selenide cigs. Worse rainwater can wash many of these toxics out of the fragments of solar modules over time.

This lack of weight gain occurred at low moderate and high doses. 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. Cdte thin film panels are made from several thin layers. Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants.

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. Thin film solar panels and toxicity cadmium telluride. Cadmium can be rinsed into the water table during the production process. One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection.

The company solyndra now. Cadmium telluride ct is a highly toxic chemical that is part of solar panels. Cadmium telluride cdte is a commonly used material in thin film solar modules. Approximately 90 of most pv modules are made up of glass.
