This chapter has shown the potential of some materials and chemicals used in the manufacture of thin film PV solar cells and modules to be hazardous. These hazardous chemicals can pose serious health and environment concerns, if proper cautions are not taken.
Once took out from the manufactory, photovoltaic (PV) systems do not produce any toxic gas emissions, any noise or greenhouse gases. However, as with any industrial product, there are health and environmental impacts associated with the manufacture of solar cells and solar panels.
This section presents the results of the evaluation of inherent occupational health hazards in the production of solar grade silicon, for three processes: Siemens, Intensified FBR Union Carbide and Hybrid.
When the solar cell panels especially perovskite solar cells are damaged, lead would possibly leak into the surrounding environment, causing air, soil and groundwater contamination.
However, this raises the question to the evaluation problem in health and environmental aspects in solar panel production. Even if the photovoltaic industry uses far fewer amounts of toxic and flammable substances than many other industries, the use of hazardous chemicals can represent occupational and environmental hazards.
The PV industry uses harmful and flammable substances, although in small amounts, which can involve environmental and occupational risks. The main environmental impacts of solar panels are associated with the use of land, water, natural resources, hazardous materials, life-cycle global warming emissions etc.
