Tungsten titanium target material as coating material of photovoltaic cells is developed recently, it acts as a barrier of the third generation solar cell is the best choice.
The W-Ti series film has excellent performance, application volume increased dramatically in recent years, the world's 2008 W-Ti target has reached 400t, with the development of photovoltaic industry, demand for this target will be more and more.
With the industry to predict the amount of its use will be greatly increased. The international solar cell market growth rate of 100%, the world has more than and 30 companies to participate in the further development of the solar market, and the company's products into the market, such as the German Wverthsurlfulcell, American Global solar Energy Honda Showa Solar shell, Japan's Hitachi Metal Ltd, etc.. Large size, high density, high pure W-Ti target of China's development, belongs to the ion sputtering target material.
The barrier layer or color layer can be widely used in display, decorative layer, solar battery package, notebook computer (PV) barrier layer of the cell, and has good market prospects and economic benefits. On the other hand, China's tungsten industry can promote the upgrading of products, to obtain a higher value added.
