An analysis of the use of semiconductor solar cells based on thin-film cadmium telluride (CdTe) in power engineering is carried out. It is shown that the advantages of thin-film technology and CdTe itself as a direct-gap semiconductor open up the prospect of large-scale production of competitive CdTe solar modules.
Cadmium telluride as a solar cell material candidate 1. The value of the energy band gap and nature of the band-to-band transitions. 2. The value of the photocarrier lifetime as a function of doping. 3. The capability of the material to be prepared economically in large areas with good electronic properties. 4.
Cadmium telluride PV is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi-kilowatt systems.
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.
PV array made of cadmium telluride (CdTe) solar panels Cadmium telluride (CdTe) photovoltaics is a photovoltaic (PV) technology based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity.
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.
