Hanwha Q CELLS is proud of our legacy of innovation and believes strongly in protecting our intellectual property.


Hanwha Q CELLS GmbH filed patent infringement complaints with the Regional Court of Düsseldorf against JinkoSolar and REC Group. The Regional Court complaints allege that JinkoSolar and REC Group are unlawfully importing and selling solar cells and modules that infringe Hanwha Q CELLS’s patented passivation technology, which plays an important role in improving the efficiency and performance of solar cells. Both defendants have unlawfully incorporated this patented passivation technology into their solar cells. Hanwha Q CELLS is seeking an order to stop JinkoSolar and REC Group from importing, marketing, and selling the infringing products in Germany.


In the United States, Hanwha Q CELLS & Advanced Materials Corp. and Hanwha Q CELLS USA Inc. filed a patent infringement complaint with the U.S. International Trade Commission (“ITC”) against JinkoSolar, LONGi Solar, and REC Group and also filed related patent infringement complaints with the U.S. District Court for the District of Delaware against the same companies. In Australia, Hanwha Q CELLS & Advanced Materials Corp, together with Hanwha Q CELLS Australia Pty. Ltd., filed patent infringement complaints with the Federal Court of Australia against JinkoSolar and LONGi Solar.


Hanwha Q CELLS’s patented passivation technology improves the efficiency of light conversion into electricity, allows more energy to be extracted from the solar cell, and enables it to remain durable through the manufacturing process. Hanwha Q CELLS began manufacturing Q.ANTUM solar cells using this passivation technology in 2012 and has produced more than 2.5 billion such cells globally.
