The hazards of photovoltaic cell welding

Are solar cells harmful to the environment?

Insufficient toxicity and environmental risk information currently exists. However, it is known that lead (PbI 2), tin (SnI 2), cadmium, silicon, and copper, which are major ingredients in solar cells, are harmful to the ecosystem and human health if discharged from broken products in landfills or after environmental disasters.

Is photovoltaics safe?

Photovoltaics is safe! It has far fewer risks and environmental impacts than conventional sources of energy. None-theless, there are some environmental, safety, and health (ES&H) challenges associated with making, using and disposing of solar cells. Is Today's PV Safe to Make and Use? Yes conditionally.

What are some examples of hazardous chemicals in PV cells?

Examples of these chemicals are hydrogen, hydrochloric acid, nitric acid, isopropanol, ammonia, and selenium hydride. Most of these compounds are flammable, corrosive, toxic, and carcinogenic, hence they require special handling. The emissions of these hazardous gases and chemical solvents vary with the type of PV cell materials.

Are solar cells toxic?

In other words, from an environmental point of view, insufficient toxicity and risk information exists for solar cells.

Are solar cells safe?

Risks of contamination by leachates containing harmful chemicals are linked to environmental disasters (hurricanes, hail, and landslides). However, research into the health and environmental safety of solar cells is rare, despite the fact that solar cell devices contain harmful chemicals such as Cd, Pb, Sn, Cu, and Al.

How do PV manufacturers reduce risks?

By using well-designed industrial processes and careful monitoring, PV manufacturers have minimized risks to where they are far less than those in most major industries. All of these risks fall well within the range already protected by OSHA and similar regulations.
