Crystalline silicon solar cells continue to see strong growth

Post Time:Dec 24,2008Classify:Industry NewsView:386

Crystalline silicon (c-Si) solar cells are maintaining the lead over thin-film counterpart in China’s solar cell industry, as the segment’s output rose to 4,000 tons in 2008--almost 10 times higher that of the 387 tons produced in 2006.

With sufficient low-cost raw materials readily available, the production of c-Si solar cells is forecast to swell to 10,000 tons or expand by 150 percent in 2010, according to Applied Materials, Inc., a US-based solar module manufacturer.

This year’s increase in the production of c-Si solar cells is expected to pave the way for a wider market base in China as it will reduce production costs and drive prices down in 2009.

The c-Si segment currently secures more than 80 percent of the global solar cell market, and has registered an annual growth of more than 40 percent y-o-y.

Being the second most abundant element on earth, silicon remains an attractive resource to solar cell makers. Li Bencheng, vice general manager at Canadian Solar Inc. (Suzhou) forecasts that silicon-based solar cells and technology will continue to dominate in the next 30 years due to a mature manufacturing technology, non-hazardous properties and high efficiency.

Thin-film segment competes for market share

The fast-developing thin-film solar cell segment is projected to own a global market share of 15 percent in 2010 and 20 percent in 2015. However, the c-Si solar cell segment presents tough competition due to its higher solar cell efficiency and sufficient raw materials.

Thin-film solar cells require less raw materials and have lower production costs, but the drawback lies in the investments needed for production line construction, Li said. A 25MW thin-film solar cell production line will entail about $147 million--20 times more than the investments needed for crystalline silicon lines.

Thin-film solar cells can be directly integrated on glass, plastic and metal plates--making the material suitable for glass curtain-wall power generation.
