Media Focus| Jinergy: Leading Energy Transition Through Independent Innovation
On March 5, when the reporters stepped into the production line of Jinneng Clean Energy Technology Ltd. (hereinafter referred to as "Jinergy"), a strong sense of technology and futurism washes over them. Amid the steady advancement of the carbon peaking and carbon neutrality goals, the company is accelerating its lead in the high-efficiency photovoltaic cell sector with an innovation rhythm of "mass-producing one generation, pilot-testing one generation, and researching one generation".
In recent years, seizing the critical window period of N-type technology iteration, the enterprise has advanced simultaneously in three cutting-edge directions: heterojunction(HJT) cells, Tunnel Oxide Passivated Contact (TOPCon) cells and perovskite-silicon tandem cells, forming a full ecological layout spanning current mainstream technologies to next-generation solutions.
Huang Jin, Senior R&D Manager of Jinergy, told reporters that through key process optimization, the mass production efficiency of HJT cells here has reached 25.7% and that of TOPCon cells stands at 27.13%. The maximum power of the conventional photovoltaic modules hits 730 watts, while the small-area conversion efficiency of perovskite-silicon tandem cells has even exceeded 31.3%, with multiple indicators ranking among the industry’s top tier.
At the intellectual property exhibition area, a set of figures is particularly impressive: the enterprise has applied for a total of 437 patents, and obtained 263 patents, including 40 invention patents, covering the entire industrial chain of cell design, processes and equipment, demonstrating that the enterprise holds core technologies in its own hands. Especially it has achieved original breakthroughs in indium-free HJT cells, which is expected to eliminate reliance on the rare metal indium and drive the photovoltaic industry toward lower costs.
Even more encouraging is that the company’s technological achievements directly serve major national strategies. The photovoltaic modules custom-designed for the Qinling Station in Antarctica can operate stably under extreme conditions such as ultra-low temperature of -55°C, strong winds and intense ultraviolet radiation, serving as a "touchstone" of its hard-core strength. The company’s products have obtained authoritative certifications in many countries, and it has been included in the national List of Photovoltaic Manufacturing Industry Standard Conditions enterprise list, being the only listed enterprise in our province.
In the intelligent production workshop, the results of digital-intelligent transformation are clearly visible: full-process automated scheduling and precise supply chain traceability have driven a year-on-year decrease of 18.32% in module costs. The independently developed HJT magnetron sputtering equipment boasts four times the capacity of imported equipment, at only half the price and with 0.3% higher efficiency, marking a major breakthrough in domestic equipment substitution.
From initial research and development to large-scale mass production, and from taking root in Shanxi to expanding globally, the enterprise is leveraging independent innovation as its driving force, striving to lead the way on the energy transition race.
