Cadmium Telluride: Characteristics and advantages
Cadmium Telluride thin-film solar cell offers the advantage of easy production, short cycle of production and the possibility of recycling the material after its life span. CdTe films have many advantages, which has led to the industry becoming more concerned about them.
The Present State of the Photovoltaic Market
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 average efficiency exceeding 12.5%. The average power output exceeds 80W. This is in contrast to domestic crystalline silicon component efficiency which has been over 17%. High-efficiency single-crystal component products with a high efficiency have reached over 20% in recent years. The power output has increased to 400W. However, domestic crystalline silicon components are less efficient and more powerful than those made by foreign enterprises. 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 huge lead in the development of thin films for cadmium-telluride. China’s development of cadmium thin films is therefore a backward step.
Cadmium Telluride Films
Although development of cadmium Telluride Film is being resisted, this technology is one of most established thin-film power generator technologies. The theoretical efficiency of thin film power generation is nearly 30% higher than that of crystalline silicon cell. This process is much simpler than those of crystal silicon cells. Cadmium telluride film has great potential for future development. To ensure that the domestic cadmium thin film industry continues to thrive, it’s important to fully understand and appreciate the cadmium thin film’s advantages. 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 other markets such as curtains walls, car roofs charging kits and backpacks. And third, make sure that recycling is done well to minimize environmental pollution.
