CMC's Sun Well Solar Introduces Thin-film PV Cells Using Tandem Technology

CMC officially steps into the solar energy industry with the completion of Sun Well Solar's first manufacturing plant. An incredible feat itself, the first ever thin-film solar power plant in Taiwan with building integrated photovolatics (BIPV) is completed in only 120 days. According to Nano Markets LC, total thin-film PV modules will grow from USD 1 billion in 2006 to 7.5 billions in 2015, making up 35% of total solar energy market.

The amorphous silicon (a-Si) thin-film PV production from Sun Well Solar has many advantages. Unlike crystalline silicon (c-Si) technology, it won't be affected by the shortage of multi-crystal silicon wafer . Sun Well Solar will produce its own TCO to achieve a cost advantage. It is also capable of generating electricity in less than ambient light environment. According to testing by NEDO of Japan (New Energy and Industrial Technology Development Organization), though a-Si thin-film PV has less efficiency than c-Si, its total annual electricity generation is actually 10% more than c-Si. Initially, the current PV module conversion efficiency is about 7% for Sun Well Solar. Its next stage plan is to develop tandem structure to push cell efficiency to 10% later in 2008. In the near future, Sun Well Solar plans to develop even higher efficiency PV cells at lower cost for customers.

In the near term, Sun Well Solar plans to integrate its thin-film PV modules with stationary power system from Evionyx Taiwan Ltd. to provide a total solution for solar power system. In addition, for ecological purpose as well as technology demonstration, Sun Well Solar will use self-made thin-film PV modules on (the outside wall of) its own manufacturing plant to showcase the best application of BIPV. The plant will also use eco-certified materials for construction and install 80% energy-saving lighting system as well as a state of the art rainwater recycling system. Sun Well Solar is confident its plant will be the epitome of thin-film PV manufacturing and energy conservation.
