Cadmium rise solar panel.

Thin film solar panels and toxicity. Cadmium fumes may cause flu like symptoms and more severe respiratory problems. Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems. They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel.

Even though the common type of solar panel is non toxic there is a type of solar cell that can contain toxic materials. 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. Cadmium telluride cdte is a commonly used material in thin film solar modules. 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.

The picture is not all rosy but if the recent past is any. Cadmium is a heavy metal and extremely dangerous. 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.

Solar panels often contain lead cadmium and other toxic chemicals that cannot be removed without breaking apart the entire panel. Worse rainwater can wash many of these toxics out of the fragments of solar modules over time. 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 fact that cadmium can be washed out of solar modules by rainwater is increasingly a concern for local environmentalists like the concerned citizens of fawn lake in virginia where a 6 350 acre solar farm to partly power microsoft data centers is being proposed.

It could be the future of solar. Cadmium is a particular toxic waste problem. What is cdte and why should i care. The debate over the toxic potential of thin film solar panels based on cadmium compounds has been reignited.

In this video i will explain what cadmium telluride or cdte solar panels are all abou. One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection. Approximately 90 of most pv modules are made up of glass. You can see the evidence on rooftops and in the desert where utility scale solar plants are popping up.
