What is a solar cell?
Solar cells are also called photovoltaic cells or solar chips, is a photoelectric semiconductor wafer, you can use solar power generation. It is light to the moment can be output voltage, and, in the conditions of the circuit will produce the current.
What types of solar cells are there?
According to the different crystalline state can be divided into: (1) the crystallization system (single crystal form, multi crystalline form) (2) non crystalline system (a-)
According to the different materials can be divided into: (1) silicon solar cells (2) polycrystalline thin film (3) organic polymer (4) nanocrystals, etc..
Solar cell according to different classifications, the coating material is different s coating material for solar cell are the most commonly used tungsten (W), silicon (Si), titanium (Ti), molybdenum (Mo), aluminum (Al), silver (Ag), chromium (Cr), copper (Cu), Zinc Oxide (ZnO (Si), Si Al:Al) etc..
The tungsten target for solar panels of pure tungsten target
Why tungsten sputtering target can be used for solar cell film?
Tungsten sputtering targets used in optical coating can improve the performance of the solar cell solar cell, and improve the conversion efficiency.
Because now fossil fuel resources have been reduced, so people gradually turn their attention to the solar energy, mainly to the light energy (light emitted by the sun) into electric energy and heat energy.
Today, solar cells have been developed to the third generation (thin-film solar cells), and the sputtering process is the first to be the preferred method of preparation. With the rise and rapid development of the global low-carbon economy, the focus of solar cell coating target has become the target of the development of products suppliers around the world. Solar cell film showing explosive growth mode, data show that from 2005 to 2007, the solar battery installed capacity of annual growth rate were 23%, 40%, 67%, this means that in the future there will be many solar cells will gradually the pursuit of higher quality, whereas tungsten is sputtering materials environmental friendly, harmless to the human body, therefore, the application of tungsten sputtering target will become a new industry in solar cell film.
