Residential, Commercial and Industrial and Utility Solar Energy (Storage) SystemN-Type TOPCon cells are based on an n-doped crystalline silicon wafer.
Photovoltaic cells differ in their layer structure into positively charged P-type cells and negatively charged N-type cells. With P-type cells, the base layer is doped with boron, which has one electron less than silicon. This creates an electron hole and the positive charge carriers predominate. In N-type cells, the base layer is doped with phosphorus. This has one electron more than silicon. This doping generates free electrons.
The higher efficiency of N-type cells is caused by these free electrons. They are also responsible for the extremely low power losses and prevent phenomena such as PID and LID.
