On December 30, Trina Solar said on the interactive platform that it is a leading enterprise in the industry with the National Key Laboratory of Photovoltaic Science and Technology. Crystalline silicon cells (HJT, etc.), perovskite tandem cells and III-V gallium arsenide multi-junction cells related to space photovoltaics have been laid out for a long time, and leading research and development results have been achieved.
In the promotion of commercial applications, based on the existing achievements, the company has worked closely with domestic aerospace institutes and enterprises, cooperated with leading overseas aerospace institutions, and accumulated a lot of practical experience in the direction of space solar energy.
At present, Trina Solar has research and development laboratories and pilot lines for HJT batteries and perovskite batteries, and HJT battery technology continues to maintain a world record of 27.08% efficiency in large areas; Leading achievements of perovskite/crystalline silicon tandem cell: at present, the efficiency of the company's small-area perovskite tandem cell is 35%, the efficiency of large-area tandem cell is 32.6%, and the module power reaches 865 Wp.
The company has reached patent technology cooperation with Oxford Photovoltaic, the world's leading enterprise in the field of perovskite solar cells, and obtained the exclusive authorization of its perovskite core patent technology in China. Tianhe's perovskite patent applications exceed those of Japanese and British enterprises, ranking first in the world, contributing to the global patent leadership of Chinese enterprises in the field of perovskite technology. The National Key Laboratory
of Photovoltaic Science and Technology, together with Fudan University and co-construction enterprises, has made new progress in high-efficiency GaAs technology, and its products have been applied in many aerospace equipment such as Internet satellites of China Star Net and continuously expanded . It will play a leading role in China's large-scale star chain construction during the 15th Five-Year Plan period.
Trina Solar said that in the future, the company will study and explore the application scenarios of various battery component products in space based on its own technology. The company will actively explore commercial aerospace/space photovoltaic customers, jointly carry out directional research and development, and provide one-stop and systematic space energy supply solutions for spacecraft in different orbits and missions.
