Disadvantages of Cadmium Telluride Solar Panels

What are the disadvantages of cadmium telluride solar cells?

The primary disadvantages of cadmium telluride solar cells include their lower efficiency in converting sunlight to electricity compared to silicon-based cells, the limited availability of the critical component tellurium, and the significant environmental and health risks associated with the toxicity of cadmium.

What are the advantages of a cadmium telluride solar panel?

The major advantage of this technology is that the panels can manufactured at lower costs than silicon based solar panels. First Solar was the first manufacturer of Cadmium telluride panels to produced solar cells for less than $1.00 per watt. Some experts believe it will be possible to get the solar cell costs down to around $0.5 per watt.

How efficient is cadmium telluride?

Continued improvements in cadmium telluride technology are pushing closer to CdTe's theoretical efficiency of above 30%. Regarding costs, CdTe solar cells are generally cheaper to produce than silicon-based cells, with prices around $0.46 per watt.

Is cadmium telluride a good material for thin-film solar panels?

Yes, cadmium telluride (CdTe) is an effective material for thin-film solar panels. However, its commercial efficiency, typically around 16-19%, is lower than that of monocrystalline panels, which currently approaches 25%.
