Cadmium Telluride for Solar Energy

--The Challenge

A client required cadmium telluride materials for solar energy technology and contacted SAM. SAM provided specific recommendations based on its expertise in materials science and renewable energy applications, thereby targeting the optimisation of CdTe for solar energy.

-The Solution

The following specifications for cadmium telluride products are recommended:

• Cell Size: The selection of cell size is important to balance efficiency, production costs and scalability. Common CdTe solar cell specifications include 3‑inch, 4‑inch and 6‑inch cells. The 4‑inch CdTe solar cell offers a higher conversion efficiency and lower production cost, thereby making it appropriate for mass production and commercial applications.
• Purity: Purity directly affects the conversion efficiency of solar cells. A higher purity level facilitates improved charge carrier transport and reduces defects that can limit performance. A purity level of 99.99% or higher is recommended to achieve optimum conversion efficiency.
• Crystal Structure: The crystal structure quality of CdTe material is directly linked to the performance and lifespan of the solar cell. A well-defined crystal structure reduces defects and improves charge carrier transport.

--Results

The considerations detailed above emphasise the significance of material quality in the fabrication of CdTe solar cells. Consequently, customers receive CdTe material that maximises conversion efficiency, stability and long-term performance.

Conclusion

Overall, CdTe solar cells exhibit high light absorption, high transmission efficiency and an optimal band gap. These characteristics make them a promising option for large‑scale solar energy generation that combines high conversion efficiency with low production costs.
