JinkoSolar has unveiled efficiency boost roadmaps for its advanced TOPCon process, including but not limited to front-side and edge passivation, optimized metallization and screen print and light trap technology to lock more sunlight drawn on the cell. The company also said it will mass produce 26.5% efficiency TOPCon in H2 2024, while confirming plans to begin mass production of 27% efficiency cells by 2025.
Jinko has used AI and big data technology in its smart factories to enhance productivity and refine product quality, while seeking to expand its TOPCon partnerships with equipment suppliers and its clients to create a stronger ecosystem. The company owns the complete TOPCon IP portfolio, having so far secured a portfolio of over 500 key TOPCon IPs.
With demand for high-performance modules rising, competition for technology advancement is also fierce. In the utility market, TOPCon’s dominance is inevitable due to its higher bifacial factor and lower temperature coefficient. In the residential rooftop sector, which minimizes the bifacial factor advantage of TOPCon, the technology has still shown a 1%-2% yield gain over conventional BC modules according to a number of real-world comparison projects conducted by third parties.
“We continue to be ahead of the technology innovation curve and, today, we are confident that our TOPCon-based technology will be instrumental in supporting the needs of our customers in all scenario applications,” commented VP Dany Qian.
“I do see a path where TOPCon could further enhance its efficiency faster than any other roadmaps,” Qian added, predicting that TOPCon as a platform technology will be dominant for a decade with TOPCon plus perovskite tandem cells set to follow pure TOPCon.
