Cadnium Teller Solar Panels

Worse rainwater can wash many of these toxics out of the fragments of solar modules over time.

Cadnium teller solar panels.

What is cdte and why should i care. They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel. Abound solar was a manufacturer of cadmium telluride modules a thin film photovoltaic technology based in the united states. Cadmium telluride while considered less dangerous in relation to acute exposure is toxic if ingested improperly handled or the dust inhaled.

First solar a us based manufacturer makes attractive pv modules that can be used in home applications. In relation to solar panels the cdte is safe while encapsulated in the module but if the panel is damaged and exposed to water the cadmium telluride could leach into the water. Cdte thin film panels are made from several thin layers. It could be the future of solar.

One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection. Cadmium telluride is a direct bandgap material with bandgap energy of about 1 45 defined ev which is well matched to the solar spectrum and nearly optimal for converting sunlight into electricity using a single junction. 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. 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.

Approximately 90 of most pv modules are made up of glass. On a lifecycle basis cdte pv has the smallest carbon footprint lowest water use and shortest energy payback time of any current photo voltai. Solar panels often contain lead cadmium and other toxic chemicals that cannot be removed without breaking apart the entire panel. 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.

In this video i will explain what cadmium telluride or cdte solar panels are all abou. 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.
