Trinasolar Tops Global Perovskite Solar Cell Patent Ranking

Trinasolar has secured the top position in the Global Perovskite Solar Cell Invention Patent Ranking, as published by intellectual property media outlet IPRdaily. With an impressive 481 patent applications, the company outpaces all global competitors in this emerging technology segment. Additionally, Trinasolar holds the second spot in two other critical categories: global solar cell and module patents, and TOPCon solar cell patents.

Patent Rankings Cover Key Solar Technologies

The rankings compiled by IPRdaily are based on keyword searches and technical classifications relevant to perovskite, solar cells and modules, and TOPCon technologies. The dataset spans global invention patents filed or published over the past decade, up to March 31. Duplicate entries—those with the same application number—were consolidated to ensure accuracy.

Gao Jifan, Chairman and CEO of Trinasolar said: “We are very honoured to receive the top ranking release by IPRdaily. Trinasolar has always regarded technological innovation as its primary driving force. We will continue to advance the coordinated development of technology R&D, intellectual property and industry standards, accelerating the research, development and commercialization of perovskite-silicon tandem technologies, and contributing to the global energy transition.”

The Promise of Perovskite Technology

Perovskite solar cells are viewed as a breakthrough in photovoltaic innovation. Known for their higher efficiency compared to traditional silicon-based solar cells, they also benefit from lower production costs thanks to low-temperature solution-based manufacturing. This makes them highly attractive for a wide range of applications and market expansion.

Strategic Investment in Perovskite Innovation

Trinasolar began its focused investment in perovskite research and intellectual property strategy in 2014. With a robust portfolio of 481 patent applications, the company now leads global innovation in this space. IPRdaily highlighted Trinasolar's partnerships with Fudan University in operating a State Key Laboratory for PV Science and Technology. The company also co-founded an Innovation Center for Next-Generation PV Technologies alongside more than 10 other industry players.

Advancing the Next Generation of Solar Products

The company is pushing the boundaries of solar efficiency through the development of crystalline silicon tandem solar cells. Trinasolar has recently broken multiple world records in both cell efficiency and module power in the perovskite-silicon tandem category. It has also secured an exclusive agreement with Oxford PV, giving it rights to research, manufacture, and distribute perovskite-related technologies in mainland China, including sublicensing options for domestic firms.

TOPCon’s Role in Future Solar Architectures

According to IPRdaily, TOPCon technology remains a dominant force in the current solar market and is highly compatible as the base layer in tandem cell structures. The integration of TOPCon with perovskite layers continues to demonstrate strong potential for improved performance and broader commercial applications. Trinasolar has been especially active in this area, filing 82.78% of its total TOPCon patents in just the last three years, among the highest growth rates in the industry.

Gao Jifan, Chairman and CEO of Trinasolar said: “We are very honoured to receive the top ranking release by IPRdaily. Trinasolar has always regarded technological innovation as its primary driving force. We will continue to advance the coordinated development of technology R&D, intellectual property and industry standards, accelerating the research, development and commercialization of perovskite-silicon tandem technologies, and contributing to the global energy transition.”
