Cadmium Telluride (CdTe) is a compound used in photovoltaic cells that consists of cadmium and telluride. It has the potential to be environmentally benign despite the hazardous nature of cadmium. Its limited supply and potential environmental hazards are the main challenges associated with this technology.
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.
The amounts of chemicals and materials used in the manufacturing of TFPV devices vary depending on the type of cell being produced. For example, the quantity of cadmium in a CIS PV module is evaluated at 0.04 g/m 2 and in a CdTe PV module at 5 g/m 2 [ 30 ].
Nevertheless, the high band gap energy (2.41 eV) of the CdS window layer results in the fact that lights at wavelength below 514 nm will be absorbed in the CdS layer. On this basis, Cadmium-based solar cells appear to be the most promising candidate for the implementation of a luminescent down-shifter.
Thin film PV (TFPV) technology contains a higher number of toxic materials than those used in traditional silicon PV technology, including indium, gallium, arsenic, selenium, cadmium, telluride [ 2 ]. These materials must be handled and disposed of properly, to avoid with time serious environmental and human health problems.
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.
