Expert Insights: Validating BC’s Global Relevance
Dr. Qi Gao, Technical Director of Solar Services at TÜV Rheinland, interpreted BC technology's reliability standards and testing systems from an international certification perspective. Mr. Gang Zhou, General Manager of the Solar Energy Division at CGC, presented empirical data demonstrating the outstanding performance of BC modules in demonstration projects. Dr. Yongqian Wang, Chief Scientist of AIKO, discussed the evolution and future vision of photovoltaic technology, particularly BC technology, from the perspective of energy transformation. Dr. Xixiang Xu, Chief Scientist and Vice President of LONGi Central R&D Institute, provided an in-depth analysis of BC technology's process innovations in the context of photovoltaic technology advancement.
Record-Breaking Efficiency & Technological Superiority
This year, BC cells achieved a new world-record efficiency of 27.81% (certified by ISFH), just 1.3% shy of the theoretical maximum. BC cells integrate both positive and negative electrodes on the backside through full back-contact electrode technology, eliminating front-side busbars shading entirely and maximizing light absorption area. This breakthrough significantly improves conversion efficiency while achieving both optical and electrical performance enhancements, solidifying BC's status as the "ultimate form of single-junction silicon solar cells.
During the panel discussion session, Mr. Zhenguo Li, Founder and President of LONGi, and Prof. Wenzhong Shen, Director of the Solar Energy Research Institute at Shanghai Jiao Tong University, along with other industry experts, shared insights on the significance of the White Paper, BC technology's core breakthroughs, and future challenges. The consensus was clear: BC technology has become the pinnacle of single-junction silicon solar cell development, with its maturity poised to drive future innovation and industry growth.
White Paper Highlights: A Blueprint for Global Adoption
Structured into seven chapters, the White Paper provides an in-depth analysis of : BC technology principles and industrialization pathways；Standardization frameworks and third-party validation；Core performance advantages (efficiency, reliability, bifaciality);Application value across utility, commercial, and residential scenarios；Ecosystem development and future trends, etc.
As the "crown jewel" of photovoltaic technologies, BC technology is poised to propel the global solar industry into a new era characterized by higher efficiency and lower levelized cost of electricity (LCOE), injecting powerful momentum into the global energy transition.
