N-type cell technology can be subdivided into heterojunction (HJT), TOPCon, IBC and other technology types. Currently, PV cell manufacturers mostly choose TOPCon or HJT to pursue mass production. The theoretical efficiency of N-type TOPCon cells can reach 28.7%, and the theoretical efficiency of heterojunction cells can reach 27.5%.
The theoretical efficiency of N-type TOPCon cells can reach 28.7%, and the theoretical efficiency of heterojunction cells can reach 27.5%. TOPCon technology is a technology based on the “N-type cell” process, and continues to develop the “tunneling through oxide layer passivation contact”.
N-type cells have many advantages, including high conversion efficiency, high bifacial rate, low temperature coefficient, no light decay, good weak light effect, and longer carrier life. N-type cell technology can be subdivided into heterojunction (HJT), TOPCon, IBC and other technology types.
Greystone’s N-type module cell attenuation is low, with only about 60% of PERC’s annual attenuation, so customers can get more power generation. Compared with other brands of conventional mono-crystalline PERC solar panels, which only have a 25-year 80% power warranty, our N-type modules can ensure more than 90% power generation after 30 years.
According to theoretical calculation, the current TOPCon mainstream battery mass production efficiency is about 23.7-23.8%, some battery manufacturers announced that they have achieved 24.0%+, including: many companies such as Zhonglai shares have achieved laboratory efficiency of 25% or more, and the future prospects are bright.
