Solar cells increase power density by 3%

China-based Comtec Solar Systems Group Ltd and Taiwan manufacturer Neo Solar Power Corp. (NSP) have jointly launched what they call the "perfect wafer" that is embedded in the "perfect cell."

Comtec Solar is a pioneer in large sized "perfect wafers." Traditionally 156mm monocrystalline solar wafers are 'pseudo-square' with the corners being cut off. The cut-off corners result in a smaller area from which solar cells and panels can capture sunlight. Comtec Solar's "perfect wafer" enables cell and panel makers to increase the active area and hence the amount of electricity generated.

NSP's new "perfect cell' using "perfect wafer" demonstrates the possibility of increasing power density by more than 3 percent, and has an average conversion efficiency of 17.8 percent. With NSP's technological advance, the cell offers extremely low light induced degradation with superior output that can easily exceed 250W.

John Zhang, chairman and CEO of Comtec Solar, said, "We are pleased to join hands with international leading solar cell manufacturers and support them in producing cells and panels of enhanced efficiency. The framework supply agreements are recognition of our efforts in strengthening R&D and enhancing production knowhow in producing high quality, large sized wafers that offer superior conversion efficiencies. We will continue our R&D effort in this regard to develop "perfect wafer" of even larger sizes to support the business growth of our customers."

Quincy Lin, chairman of NSP, said, "Including such a creative wafer maker into our diversified wafer base shall further enhance our capacity on volume delivery of the newly launched 'perfect cell.'"
