In March 2023, the Ministry of Science and Technology (MOST) approved the restructuring of the “State Key Laboratory of PV Science and Technology”, with Trina Solar and Fudan University enlisted as its supporting entities. Formerly recognized as the “State Key Laboratory of PV Science and Technology”, the Laboratory gained approval from the Ministry of Science and Technology in February 2010 and successfully passed its acceptance inspection on November 3, 2013.

The Laboratory concentrates on investigating novel mechanisms for achieving high-efficiency photovoltaic conversion in crystalline silicon cells and advancing industrialization. It also delves into cutting-edge technologies aimed at realizing low-cost, high-efficiency perovskite cells, as well as key technologies necessary for the industrialization of ultra-high-efficiency gallium arsenide-based multi-junction cells. This research is intricately connected with the primary strategic requirements of national energy development. The objective is to comprehensively bolster the foundational, cutting-edge, and applied aspects of photovoltaic science and technology.

The Laboratory has assembled a team of proficient scientific and technological experts, encompassing both young and mid-career professionals alongside promising young technical talents. The team comprises over 200 permanent members, with more than 90% of scientific researchers holding doctoral and master's degrees, and over 80% of them are under the age of 45.

The Laboratory has undertaken over 30 national scientific research projects and has set 25 world records in both crystalline silicon cell efficiency and module power. It currently retains the world record for the efficiency of crystalline silicon cells such as PERC and TOPCon. Its perovskite crystalline silicon stacked solar cells boast industry-leading efficiencies. Its triple-junction gallium arsenide-based cell has pioneered new avenues in aerospace applications. Furthermore, the Laboratory’s provision of China’s first fully flexible gallium arsenide-based solar cell module has undergone successful rail testing, showcasing outstanding performance on the rails.

The Laboratory has garnered over 30 awards at provincial and ministerial levels. One of its notable technological advancements, high-efficiency crystalline silicon solar cells, clinched the second prize of the State Technological Innovation Award. With a publication record exceeding 600 papers, including four in prestigious journals such as Nature and Science in the realm of perovskite research, the Laboratory has made significant contributions to scholarly discourse. It boasts a substantial portfolio of over 400 invention patents and has secured more than 140 PCT and overseas patents. On behalf of Chinese PV organizations, it has pioneered the proposal of and issued international IEC standards.
