Yingli MWT solar cell conversion efficiency is expected to exceed 21%

863 major issue that the "efficiency of 20% or more new electrode structure of crystalline silicon cell industry sets of key technologies and demonstration production line" Power Valley International Hotel at the start.

According to reports, the subject by the State Key Laboratory Yingli Group, led R & D cooperation model adopted, is divided into three tasks. Where "more than 20% efficiency new electrode structure of crystalline silicon cell industry sets of key technologies and demonstration production line" task is the Ministry of Science, "solar energy technology development," second five "special plan" important projects. In February this year approved the implementation of the project by Yingli Group, Institute of Semiconductors, Chinese Academy of Sciences, Institute of Microelectronics, Beijing University of Aeronautics and Astronautics shared responsibility, focusing on the critical N-type MWT monocrystalline solar cell technology core, Yingli Group's existing "Panda" monocrystalline battery technology based on the re-innovation, MWT technology and integrated N-type crystalline silicon cells, N-type crystalline silicon to improve battery performance, improve cell conversion rate, reducing battery costs for achieving the overall level of China's photovoltaic industry has an important significance .

Yingli Group CTO Dr. Song Dengyuan said the project targeting the international advanced level, the use of proprietary advanced technology and new technology roadmap to achieve the N-type monocrystalline silicon solar cell conversion efficiency further improved, and the completion of an annual exemplary 30MW production line.

Currently, Yingli Group "Panda" N-type silicon solar cell panel conversion efficiency of 20% experiment, is one of the three largest high efficiency solar cells, the generation of highly efficient MWT solar cell conversion efficiency is expected to exceed 21%.
