Cadmium telluride (CdTe) solar cells contain thin-film layers of cadmium telluride materials as a semiconductor to convert absorbed sunlight and hence generate electricity. In these types of solar cells, the one electrode is prepared from copper-doped carbon paste while the other electrode is made up of tin oxide or cadmium-based stannous oxide.
The United States is the leader in cadmium telluride (CdTe) photovoltaic (PV) manufacturing, and NREL has been at the forefront of research and development in this area. PV solar cells based on CdTe represent the largest segment of commercial thin-film module production worldwide.
Cadmium telluride photovoltaic cells have negative impacts on both workers and the ecosystem. When inhaled or ingested the materials of CdTe cells are considered to be both toxic and carcinogenic by the US Occupational Safety and Health Administration.
1. Introduction Cadmium Telluride (CdTe) thin film solar cells have many advantages, including a low-temperature coefficient (−0.25 %/°C), excellent performance under weak light conditions, high absorption coefficient (10 5 cm⁻ 1), and stability in high-temperature environments.
Proponents claim that cadmium in the form of a thin film solar cell is more stable and less soluble than in other electronics and that there would be little risk to health and the environment, as the alloys are encapsulated within the modules. However, there have been concerns regarding cadmium leaching from broken modules.
PV solar cells based on CdTe represent the largest segment of commercial thin-film module production worldwide. Recent improvements have matched the efficiency of multicrystalline silicon while maintaining cost leadership.
