On January 5, LONGi released its latest record of investor relations activities, providing detailed responses to key concerns raised by institutional investors regarding the company’s strategic positioning and technology roadmap.
Regarding the energy storage business, which has drawn increasing market attention, LONGi stated that it plans to leverage its globally established brand and channel advantages, combined with the technological expertise of Suzhou Jingkong, to achieve complementary strengths. At present, the company is conducting a comprehensive review and further planning of the target markets for its energy storage business. The domestic market, along with major overseas markets such as Europe, the United States, and Australia, will be the primary focus of its deployment.
In terms of cost control and upstream and downstream pricing across the industry chain, LONGi addressed concerns over the recent rise in silver prices and other bulk auxiliary materials. The company expects to begin mass production of base-metalized products in the second quarter of 2026 to mitigate the impact of rising silver prices and further reduce module costs. Relevant capacity construction has already been initiated.
LONGi also disclosed its latest progress in cell technology research and development. In November 2025, the company, in collaboration with a scientific research team, published research results in Nature. Its ultra-thin crystalline silicon–perovskite tandem solar cell achieved a certified efficiency of 33.4% for small-area devices, as verified by NREL, while commercial-size flexible tandem cells reached an efficiency of 29.8%.
Despite these technological breakthroughs, LONGi noted that it currently has no plans for the mass production of perovskite tandem cells. The company will continue to focus on tracking technological pathways and advancing industrialization research in this field.
