product introduction

TOPCon is one of the technical pathways for N-type solar cells and is expected to replace P-type solar cells as a new generation solar cell technology, thanks to its apparent advantages. In comparison to traditional P-type solar cells, N-type solar cells have advantages such as high conversion efficiency, high bifaciality, low temperature coefficient, almost no light-induced degradation, and good performance in low-light conditions. It is widely regarded in the industry as the next generation solar module technology.
