Recently, the photovoltaic integrated leader Longji Green Energy announced at its performance briefing that it will shift its technical focus to the BC battery field in the next five years, which has attracted market attention.

In recent years, the photovoltaic cell technology has undergone a transformation from BSF to P-type PERC, and the PERC battery market share in 2022 is still 88%, maintaining the mainstream position in the market.

However, as the photovoltic conversion efficiency of PERC batteries approaches the limit, the market share of N-type battery technology, which has achieved technological breakthroughs, has gradually increased, and the total market share in 2022 is about 9.1%.

Among N-type battery technologies, TOPCon technology currently has the fastest progress, with a market share of 8.3%, and XBC technology has also completed large-scale mass production, while HJT battery chips have a small scale of production and mass production.
