As the new generation of n-type battery technology becomes increasingly popular, photovoltaic companies are placing greater emphasis on the patent protection of n-type battery technology. Leading firms such as Jinko Solar and Trina Solar are actively advocating for and taking action to demonstrate their commitment to this cause.
The photovoltaic industry is witnessing frequent “patent wars.” Recently, Jinko Solar’s lawsuit against Astronergy made significant progress at the European Patent Office (EPO), where the contested patent EP2787541B1 was upheld during oral proceedings. This ruling provides early insights into the case and could significantly influence subsequent litigation strategies.
In 2024, the emphasis on intellectual property (IP) protection in the photovoltaic sector is on the rise. Companies like Trina Solar and Jinko Solar have initiated lawsuits, reflecting the industry’s urgent need for patent protection. Jinko Solar has filed allegations against Astronergy regarding TOPCon battery technology in lawsuits based in Munich and Hamburg.
Industry experts point out that intellectual property is a reflection of innovation and is crucial for market competition. As patent disputes increase, the growing importance of IP signifies a maturing market. While short-term patent conflicts may create pressure for the defendants, protecting intellectual property aligns with industry development trends, encouraging technological innovation and promoting healthy growth in the photovoltaic sector.
According to forecasts, by the end of 2024, n-type battery cell production capacity is expected to reach 1,078 GW, indicating rapid transformation within the industry. Jinko Solar performed exceptionally well in the first half of the year, achieving a shipment volume of 38 GW, ranking second globally, significantly outperforming Astronergy’s 18 GW.
It is widely recognized that leading photovoltaic manufacturers like Trina Solar and Jinko Solar, by launching patent protection actions, are actively safeguarding their intellectual property interests. This effort not only seeks to deepen the potential for technological innovation and IP benefits within the photovoltaic sector but also plays a crucial role in guiding the industry towards high-quality global development through a robust IP protection framework.
