CIGS thin film solar cells with low cost
Cable network [] with the global energy situation is tight, the environmental pressure gradually increased, the countries all over the world clearly recognize the need to speed up the adjustment of energy structure, increase the proportion of non fossil energy consumption of fossil energy, solar power is the best choice to replace. Thin film technology of solar technology, especially CIGS (CIGS) thin-film power generation technology in recent years, the strong momentum of development, the CIGS thin film solar cells accounted for the proportion of global thin film battery production rose rapidly from 20.5% in 2011 to 40.39% in 2013.
CIGS thin film solar cells have many advantages, such as low cost, CIGS battery with a float glass substrate on the cheap, large-scale industrial production, such as high efficiency of battery, battery price per watt than the corresponding calculation of monocrystalline and polycrystalline silicon solar cell prices much lower. And the CIGS thin film solar cell has a good stability and without S-W effect play its good characteristics can also in the light of poor area.
CIGS thin film solar cells than that in crystalline silicon solar cells made of raw materials in the process will produce a large number of pollution, the main raw material of copper, indium, gallium and selenium pollution problem does not exist, material and process, and the four largest producer of raw materials are also in China, the independence of the Yu Zengqiang energy.
