Solar panels are made with PV (photovoltaic) cells of silicon semiconductors that absorb sunlight and create an electric current. 95% of all photovoltaic cells are made entirely of Silicon, an element so common that it makes up 27.7% of the entire Earth’s crust and is the second-most abundant element we have (second only to Oxygen).
Arsenic, gallium, germanium and hexavalent chromium, for example, have been listed as present in solar panels by several US state health department websites, despite the fact that the two dominant module technologies, which account for over 99% of the market, contain none of these materials.
As the solar industry continues to innovate, the aluminum used in panel frames remains a focal point of the design for efficiency and sustainability. The manufacturing of solar panels involves various chemicals such as silicon, cadmium telluride, and lead, which must be handled with care to avoid environmental contamination.
Polyvinyl fluoride (PVF), known under the brand name Tedlar®, is typically used as a backsheet material to protect the panel from damage. Silver is crucial for its conductivity and is used to make the conductive paste that forms the grid-like pattern on the solar cells. Aluminum frames the solar panel, providing structure and support.
The aluminum frames and trace elements of silver are the most valuable components. When standard silicon-photovoltaic-cell solar panels are broken apart there are no major toxic chemicals released into the environment.
The materials used in making thin film solar panels can be toxic. These toxic chemicals are introduced into the environment in two stages of a solar panel’s lifespan – production and disposal. During production, these chemicals are gathered, manipulated, heated, cooled, and a plethora of other processes which involve human beings in every step.
