It includes but is not limited to front-side passivation, edge passivation, optimized metallization and screen print, light trap technology to lock more sunlight drawn on the cell, etc. The PV giant also said it will mass produce 26.5% efficiency TOPCon in H2. Looking ahead, JinkoSolar also confirmed its plans to begin mass production of 27% efficiency cells by 2025.
In addition, JinkoSolar has used AI and big data technology in its smart factories to enhance productivity and refine product quality. Also, the Company is seeking to expand its TOPCon partnerships with its equipment suppliers and with its clients to create a stronger ecosystem. Compared to BC players, except its IP owner, from upstream makers to downstream end users taking IP risk, JinkoSolar who owns the TOPCon’s complete IP portfolio is the safest supplier and chain owner. So far it has 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. While in the residential rooftop sector which minimizes the bifacial factor advantage of TOPCon, TOPCon still has 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,” said Dany Qian, VP of JinkoSolar.
In spite of looming competition, JinkoSolar has far surpassed its rivals as the world’s definitely largest module supplier with about 43.8GW of module shipment in H1 2024, making it increasingly difficult for its biggest competitors to catch up in the short term.
“I do see a path where TOPCon could further enhance its efficiency faster than any other roadmaps,” Dany said. She predicted TOPCon as a platform technology will be dominant for a decade in considering TOPCon plus perovskite tandem cells after pure TOPCon.
