On April 21, IPRdaily, a world-renowned comprehensive intellectual property information service provider, released the "Global Solar Cell and Module Invention Patent Ranking (TOP 50)" and "Global"perovskite solar cellsInvention Patent Ranking (TOP30) and Global TOPCon Solar Cell Invention Patent Ranking (TOP30). Among them, among the top three companies in the global perovskite patent layout,Trina SolarAs the only China company, it ranks first in the world with 481 patent applications, far exceeding the second place by nearly 40%. At the same time, Trina Solar ranks second in the global solar cell and module patent list and second in the global TOPCon solar cell invention patent list.
The three major lists are limited based on keywords and classification numbers related to perovskite solar cell technology, solar cell and module technology, and TOPCon solar cell technology, respectively. Statistics are made from April 1, 2015 to March 31, 2025. Perfume solar cell invention patents, solar cell and module invention patents, and TOPCon solar cell invention patents (merged with application numbers).
As a next-generation photovoltaic technology, perovskite solar cells have shown huge development potential. Its efficiency is significantly higher than that of traditional silicon-based photovoltaic cells. In addition, perovskite materials can be prepared through low-temperature solution processing processes, which reduces manufacturing costs and expands application fields.
Since 2014, Trina Solar has continuously increased its investment and layout in the perovskite field, leading the world with 481 perovskite patents, far surpassing international giants Panasonic (347) and Oxford PV (365). As IPRdaily pointed out in the interpretation of the list, Trina Solar and Fudan University jointly build the National Key Laboratory of Photovoltaic Science and Technology, and jointly build a new generation photovoltaic technology and equipment manufacturing innovation center with more than 10 companies in the industrial chain, actively deploy a new generation of photovoltaic products-crystalline silicon laminated solar cells, and in 2025 announced that it has broken world records in the field of perovskite crystalline silicon laminated technology from battery efficiency to component power. At the same time, it has obtained the exclusive license to develop, manufacture, sell, promise to sell, use and distribute perovskite battery technology, perovskite/perovskite laminate technology and perovskite/crystalline silicon laminate battery photovoltaic products in mainland China, as well as the exclusive right to sublicense to local manufacturers.
IPRdaily data shows that China companies and universities account for 56% in the perovskite patent field. Among them, Trina Solar, as the only China company to rank among the top three in the world, is leading China's innovative forces to reshape the global photovoltaic industry.
IPRdaily pointed out in the list that TOPCon technology not only dominates the current market, TOPCon is more suitable as the bottom battery of laminated batteries. TOPCon+ perovskite laminated battery technology will continue to have strong vitality and is expected to further improve efficiency and expand application fields in the future. In the past three years, Trina Solar's TOPCon patent applications accounted for 82.78% of its total in the past ten years, and its growth rate is also among the forefront of the industry.
"Protecting intellectual property rights means protecting innovation." Trina Solar has always regarded technological innovation as the first driving force, continues to promote the synergy of technology research and development, intellectual property rights, and industry standards, and deepens the research and development and industrialization of perovskite crystal silicon laminate technology., contributing to the promotion of global energy transformation.
