LONGi introduced that its upgraded Hello-MO 9 photo voltaic panel with back-contact “HPBC 2.0” know-how has reached 24.8% effectivity with a most energy output of 670 W.
By integrating zero busbars with half-cell structure, LONGi was in a position to enhance the modules energy output by 10 W. The optimized rear-side grid design elevates the panel’s bifaciality to over 80%, the corporate claims. The back-contact Hello-MO 9 delivers 1.5% extra higher effectivity than TOPCon manufacturers.
Moreover, LONGi introduced it has reached 27.81% effectivity for its self-developed heterojunction interdigitated again contact (HIBC) photo voltaic cells, as licensed by Germany’s ISFH (Institute for Photo voltaic Power Analysis Hamelin).
To additional amplify the market potential of high-efficiency BC know-how, LONGi partnered with TÜV Rheinland to launch the “World Optimum BC Photo voltaic Energy Plant Design Problem.” The competitors, open to consultancies, EPC companies and renewable power buyers worldwide, invitations revolutionary designs for ground-mounted energy plant initiatives exceeding 50 MW throughout various software situations. Submissions will be accepted from April 11 to November 30, 2025. TÜV Rheinland will lead an knowledgeable panel in rigorously evaluating entries based mostly on BC know-how integration, PVsyst simulation outcomes and design innovation. The full prize purse quantities to roughly $280,000.
Dennis She, Vice President of LONGi, emphasised: “BC know-how represents the final word development in crystalline silicon photo voltaic cells. With a mature international ecosystem, high-efficiency BC modules are quickly being deployed throughout various functions. The upgraded Hello-MO 9, powered by HPBC 2.0, will ship unparalleled worth to clients worldwide. We’re dedicated to sharing BC improvements with international companions to construct a sustainable future.”
