During the recent Back Contact Eco-Innovation summit in Jiaxing City, LONGi and industry partners jointly launched the Global BC Ecosystem Collaborative Innovation Centre, aiming to accelerate the industrialization process of BC technology.
At the summit, Laplace New Energy Technology, Xingbei New Energy Technology and Haida New Energy Materials signed agreements to join LONGi’s “Pathfinder Alliance Program”. As key members of the BC ecosystem, they will collaborate with LONGi on joint R&D and production.
At the event, LONGi founder and CTO Li Zhenguo issued a call to action to “Establish an open and sharing BC innovation ecosystem characterized by collaborative advancement, accelerating technology integration and commercialization to unleash the full innovative potential within the ecosystem.”

BC technology is emerging as a key enabler driving the industry’s transformation, but it constitutes a systematic engineering challenge, in that mastering the technology demands exceptional expertise. Similarly, the technology’s scaled deployment demands cross-value-chain collaboration, industry-academia-research synergy and system innovation targeting efficiency, cost and quality.
As a global leader in solar technology, LONGi was the first to initiate the construction of a BC ecosystem, fostering an open, collaborative and win-win innovation environment where it works with partners to co-innovate and achieve shared success.
Building on its past successes and the collaborative model, the company has established a comprehensive system featuring dedicated organizations, end-to-end processes, full lifecycle tracking and a benefit-sharing mechanism. It is committed to building an open innovation ecosystem centered on independent innovation, synergistic collaboration, intellectual property protection and business safeguarding.
As of the end of May, LONGi had conducted technical exchanges with 191 global ecosystem partners, secured 55 cooperation agreements with 44 partners and completed 23 strategic technology deployments across the industrial chain. These span seven key fields: wafers, cells, modules, system solutions, hydrogen, biomass and engineering technology.
