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.
In the manufacturing process of photovoltaic cells, health may be adversely affected by chemical hazards related to the materials' toxicity, corrosivity, flammability, and explosiveness. The discussion in this chapter focuses on these chemical hazards, which vary with technology and processes.
What is the photovoltaic effect?
The photovoltaic effect is defined as the process that generates either voltage or current when the device (or solar cell) is exposed to a light source of a suitable wavelength. Solar photovoltaics (PV) employs the photovoltaic effect to produce electricity from solar radiation.
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.
Are there occupational health hazards in the production of solar grade silicon?
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.
What is photovoltaic technology?
Photovoltaic (PV) technology such as solar cells and devices convert solar energy directly into electricity. Compared to fossil fuels, solar energy is considered a key form of renewable energy in terms of reducing energy-related greenhouse gas emissions and mitigating climate change.
Are solar photovoltaics a potential energy source for the future?
The limited availability of fossil fuel sources coupled with the health and environmental risks associated with their use lead to the increased focus on renewable energy resources such as solar photovoltaics (PV) as a potential energy source for the future.
