Jiang Bing, Director of the Planning Department of the National Energy Administration, recently stated that the "Emerging Energy Industry Development Plan" has been completed in a mature draft, with a planning period of 2011-2020, and is currently being prepared to be submitted to the State Council. Among various new energy sources, the hydropower power generation industry in the Mainland is quite mature; wind power generation is high-cost, limited by location and climate, and the output is unstable; while China has a vast land, and solar energy in plateau and desert areas such as the Northwest, Inner Mongolia, and Qinghai It is rich in resources and ranks second in the world, second only to the Sahara Desert. It can be seen that China's solar photovoltaic industry has the broadest prospects.
Jiang Bing pointed out that polycrystalline silicon has always been the main material for manufacturing solar photovoltaic panels. Although the price has stabilized after reaching its peak in 2008, the cost of polycrystalline silicon solar modules is still much higher than that of amorphous silicon thin film solar modules; and polycrystalline silicon is in production The process consumes a lot of energy, pollutes a lot and makes the cost higher.
Amorphous silicon thin film is another main material of solar photovoltaic panel components. The principle of thin film solar cells is to make multi-layer thin films into solar cells, which use very little silicon. In addition, compared with polysilicon whose energy payback period is 5 to 7 years, the payback period of amorphous silicon thin films is only 1.5 years, which can further reduce production costs and reduce pollution.
In terms of energy conversion efficiency, polycrystalline silicon has a conversion efficiency of 13% to 15% due to the unchangeable physical properties of silicon, while amorphous silicon thin films depend on the chemical properties of different segments of materials. substances to improve the efficiency of energy conversion. The current conversion efficiency is 8%-10%. It is expected that the conversion efficiency can be further improved to 10%-12% in the next 1-2 years. This will make amorphous silicon films more competitive and is expected to drive With the demand for amorphous silicon thin films, iSuppli expects the share of solar modules using thin film technology to double from 14% in 2008 to 31% in 2013. Judging from the above factors, thin film technology will dominate the market in the future.
