Cadmium Telluride: Characteristics and advantages
Cadmium telluride thin films solar cells offer the advantage of easy production, short cycle time and the possibility of recycling the cell after its life span. CdTe films have many benefits and are now being used in a variety of industries.
The current State of the Photovoltaic Industry
As the market for photovoltaics is maturing, there are many products that compete. There is no suspense in the battle for product of thin film and crystal silica. The cost of thin film products is falling and it will become difficult for them to be competitive. There won’t even be a market place for those products if they are not competitive. Longyan Energy’s thin-film modules have an efficiency exceeding 12.5%. The average power output exceeds 80W. This is in contrast to domestic crystalline silica components which are only 17%. High-efficiency single-crystal component products with a high efficiency have grown to over 20% in recent years. The power output has increased by 400W. However, domestic crystalline silicon components are less efficient and more powerful than those made from crystalline silica components. The American thin-film manufacturer First Solar was the first to produce CdTe cells. The technology has been around for a while.
CdTe thinfilm cells have a lab efficiency above 22.1%. Its component efficiency was about 19.5%. First Solar holds a leading position and even a monopoly on the market for cadmium-telluride thin film. China’s development of cadmium thin films is therefore a backward step.
Cadmium-Teluride Films in the Future
Although development of cadmium Telluride Film is being hampered at the moment, this technology is one of most established thin-film power generator technologies. With a theoretical efficiency value of nearly 30% higher than that of crystalline silicon cell, an easier process than those cells, as well as advantages like flexibility and high temperatures performance, Cadmium telluride film has great future potential. To ensure that the domestic cadmium thin film industry continues to thrive, it’s important to fully understand the benefits and features of this thin film. Reduce production costs by doing so in an efficient manner, realizing localization of production equipment quickly and continuing to innovate to lower production costs. Second, the flexible nature of cadmium Telluride Film will allow it to be turned into curtain walls and car roofs as well as backpacks and charging kits.
