Hazards in this stage are mainly chemical in nature. They include crystalline silicon, amorphous silicon thin film, cadmium telluride thin film, copper indium selenide, copper indium gallium selenide, and gallium arsenide. These are highly toxic and flammable; hazardous exposures can come via chemical burns, explosions, and inhalation of gaseous fumes.

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.
