China Sunergy has announced its monocrystalline solar cells reached a record 20.26% efficiency.

The cells reached the new landmark in conversion efficiency during pilot research and development with the record certified by the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE), the largest solar research centre in Europe.

China Sunergy claims its new record breaking cell is a combination of breakthroughs with its previous cells, Waratah and QSAR.

Using a new design structure with normal wafers, China Sunergy was given ISE certification as the leading conversion level amongst Chinese PV companies.

The company plans for mass commercial production of the new high-efficient cell to start by the end of next year and has installed a 70MW capacity production line.

Jianhua Zhao, chief technology officer of China Sunergy said: “We are proud of our record achievement, and aim to promptly deploy this new breakthrough for large-scale commercial application. Our success validates the hard work and diligence of our dedicated R&D team, and we remain determined to further advance the state of the art and to foster healthy and sustainable development for solar energy”.

The high-efficiency cell surpasses the benchmark of 20% conversion efficiency, set by development guides by the state council for China’s photovoltaic industry, in July 2013.
