JinkoSolar has achieved a new record efficiency for a large-area n-type TOPCon monocrystalline solar cell, taking its efficiency to 25.25%.  

The ‘Solar Module Super League’ (SMSL) manufacturer said it had recorded a maximum conversion efficiency of 25.25%, a new record for a contact-passivated solar cell, a performance independently confirmed by China’s National Institute of Metrology.

Jinko said it was third time the manufacturer had set a new efficiency record in this field in less than a year, having achieved an efficiency of 24.9% in January. It tops the previous efficiency record of 25.09% set by LONGi last month, which was the first time an n-type TOPCon cell produced an efficiency rating beyond 25%.

Jinko achieved the record by making a number of upgrades to the cell process and fabrication of Czochralski silicon substrates, using a practical cell size of 267.4cm2. Further advancements were made to the manufacturer’s n-type wafer, passivating contract technologies, diffusion system, surface passivation, cell metallisation and other technologies.

The company added that the breakthrough also paved the way for the mass production of n-type TOPCon cells to take hold.

Hao Jin, chief technology officer at JinkoSolar, said each milestone recorded by the company was testament to its R&D capabilities.

Investment in n-type solar cell technologies and production efforts has continued to rise and PV Tech’s in-house market research team has forecasted them to dominate solar industry spending from 2024 onwards, with n-type cell capacity to exceed 15GW by the end of this year.

FREE WEBINAR -This special webinar will take a deep dive into the latest PV ModuleTech Bankability Ratings pyramid, capturing the relative bankability status of the top 70-80 PV module suppliers globally. In addition to revealing the latest ranking of global PV module suppliers, PV Tech’s Head of Research, Finlay Colville, will show the depth of analysis and commentary included within the report for module suppliers. A key output from the webinar will be to learn which PV module suppliers have moved up the rankings pyramid in recent years and why this growth has been achieved. Conversely, some of the companies that have fallen down the rankings will be discussed, in particular those suffering from market-share losses and financial problems.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 8-9 October 2024 is our second PV CellTech conference dedicated to the U.S. manufacturing sector. The event in 2023 was a sell out success and 2024 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
