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.
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%.
Based on the research on BRL generation and its impact on cell effect, an emitter preparation process without post-oxidation was developed. The use of the emitter prepared by this process in the n-TOPCon cell resulted in a final efficiency of 26.28 %. The industrial advantages of this approach were elucidated through cost analysis.
This method was applied in uniformly junctioned n-TOPCon cells with overlaying LECO technology, achieving a conversion efficiency of 26.28 %, representing a 0.03%–0.05 % efficiency improvement compared to cells prepared with traditional boron-diffusion processes.
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.
