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.
Better optical designs and enhanced recovery of tellurium may boost the potential for large-scale energy production from thin-film cadmium telluride solar cells. For decades, the material associated with photovoltaic (PV) cells has been silicon.
Cadmium telluride PV is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi-kilowatt systems.
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.
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.
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.
Cadmium-telluride—Material for thin film solar cells
Due to its basic optical, electronic, and chemical properties, CdTe can become the base material for high-efficiency, low-cost thin film solar cells using robust, high-throughput manufacturing techniques. CdTe films suited for photovoltaic energy conversion have been produced by nine different processes. Using n -type CdS as a window-partner, solar cells of up to 16% efficiency …
