Jolywood Vice President Dr. Liu Zhifeng Explains the development trend of N-type cell technology
Dr. Liu said that Jolywood has been engaged in the production and R&D of N type bifacial cells for more than 6 years, and has shipped N type cells and modules over 4.1 GW after years of efforts. Many projects around the world use our N type products which were deeply recognized by customers. Currently, N TOPCon technology has become a hot spot in the market, and is also considered to be the direction of the next generation of crystal silicon technology development. Jolywood will seize the opportunity to actively develop new technologies and announced a production capacity expansion plan of 16GW TOPCon cells, which is expected to be completed in the next year. Jolywood will have more than 10GW TOPCon cells production capacity by then.
Currently, large size of silicon wafer in the market is the trend of industry development. The modules used 182/210 wafer have become a popular new star in PV industry. The new product released at SNEC is Niwa Max, a 700W super high power TOPCon module based on 210 silicon wafer. The launch of this product will guarantee lower LCOE for our customers. “We hope Niwa Max can bring great value to our customers in the future and promote the early arrival of “carbon neutrality, emission peak”.” Dr. Liu said.
At present, ground power stations are still the mainstream demand of PV market, accounting for more than 70% of global market. As for ground power station, the investment income and LCOE are the primary factors to decide the investment of power station. Compare with HJT and IBC, TOPCon has same mass production efficiency, but the lowest manufacturing costs per watt among them and also have the more competitive LCOE than the current mainstream PERC module.
PERC cell’s efficiency improvement has encountered a great bottleneck since last year. Therefore, many leading solar companies already focused their attention on N type technology. After many years’ effort of Jolywood, now it can be able to coverage the unit GW capacity investment and non-silicon cost of TOPCon cells with PERC almost within 1 cent. Therefore, compared with PERC, TOPCon cells have increasingly obvious cost-effective advantages.
Recently, other leading companies in PV industry have started to make announcements about the TopCon cells efficiency and their plans to start TopCon cell manufacturing technology. Many leading companies were showing N type products and TOPCon technologies at SNEC this year, which indicated that a large-scale expansion of the N type cell production capacity will be formed in the next two to three years.
