Citing an industrywide conversion efficiency average of 5-6% for amorphous silicon (a-Si) thin film modules, Anwell Technologies has claimed that it has reached efficiencies of 8.58% at its 40MW thin film plant in Henan, China. The results were said to have verified by the National Laboratory of China and tested according to the IEC61646 standard. The company has not announced if its modules use a tandem cell structure, which has been typically claimed to have efficiencies of between 7 and 9%.
“We are pleased to have our panels tested and certified by such a prestigious national laboratory in China,” commented Franky Fan, Chairman and CEO of Anwell Technologies. “The positive results from the tests are proof that panels produced by our in-house developed technologies are able to meet the most rigorous of international standards. It also validates the capabilities of our proprietary designed equipment and process capability. We are looking for further process enhancement as to maximise the capacity of the production line.”
Anwell is running final tests at its first thin film plant and is on track to begin volume ramp by end of March. In mass production, the company said it expects stabilized conversion efficiencies above 7% for its modules.
It has also started construction of two PV power plant projects under the ‘Golden Sun’ stimulus programme in China. Both projects are expected to be completed in July 2010.
