Cadmium Solar Panel Recycling

The solar panel recycling process.

Cadmium solar panel recycling.

This work was funded by the solar technologies program conservation and renewable energy united states department of energy under contract de aec02 76ch000016 and by a research grant provided by first solar ltd. The international renewable energy agency estimated that there were about 250 000 metric tons of solar panel waste in the world at the end of 2016 and that the figure could reach 78 million metric tons by 2050. Even though the common type of solar panel is non toxic there is a type of solar cell that can contain toxic materials. Solar panels are warrantied to perform more than 25 years and once the warranty expires panels will still produce energy albeit not at their advertised peak.

Cadmium telluride cdte photovoltaics describes a photovoltaic pv technology that is based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity. Conventional solar cells are made by cutting wafers from a block of. Pv cycle a nonprofit dedicated to solar panel take back and recycling collects several thousand tons of solar e waste across the european union each year according to director jan clyncke.

The most difficult and expensive part of recycling solar panels is breaking them down into their component parts. However an industry that is proud to promote clean energy consumption and that is proud to be a sector concerned about climate change cannot forget to dispose properly of the electronic products that exceed their lifespan. Solar panels contain lead cadmium and other toxic chemicals that cannot be removed. Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems.

Thin film solar panels and toxicity. Environmental scientists and solar industry leaders are raising the red flag about used solar panels which contain toxic heavy metals and are considered hazardous waste. With recycling expensive. A 2018 report from the institute of energy research suggests imposing a recycling fee on solar panel purchases.

Solar panel disposal and recycling isn t a huge issue right now in 2018 because there isn t a big enough volume to cause concern. Once that is done most parts are recyclable. Solar panels a big industry that must take care about recycling the solar industry growth rates keep increasing every year across the world almost exponentially.
