October 8 from the CLP photovoltaic news came from the CLP as the main commitment unit of the national 863 major task - "efficiency of more than 20% based on efficient back-field and back-passivation technology of crystalline silicon battery industrialization complete sets of key technologies and Demonstration production line "project made significant new progress, since mid-September 2014 has entered the batch trial stage. According to the introduction of the project team, CLP's PERC high-efficiency battery adopts a new battery structure design. Using ordinary solar grade silicon chips, only a small amount of equipment is added to the ordinary battery production line, and the battery conversion efficiency is 0.6% -1 % Improvement. Under this new technology, we can mass-produce PERC high-efficiency cells and complete the seamless connection between low-cost and high-efficiency solar crystalline silicon cells and the existing production lines by upgrading and renovating the production lines based on the existing battery production lines. At present, the prototype battery is in the process of preparing the component products, and the subsequent reliability testing and certification of the components are performed. According to the standard of Fraunhofer Institute for Solar Energy Systems in Germany, the average efficiency of PV high-efficiency battery batch products reaches 20.3% -20.4% and the efficiency of single chip is over 20.6%. The batch trial production is successful. By the end of 2014, CEC PV plans to fully mass-produce high-efficiency battery projects with a conversion efficiency of over 20%, further improve battery conversion efficiency, reduce power generation costs and increase the cost competitiveness of photovoltaic power generation and conventional thermal power generation. This is of great significance for firmly grasping the supreme position of the future energy industry, forming the core competitiveness in the domestic and international markets and promoting the rapid and healthy development of the country's new energy sources .
