The P-N junction houses p-type crystalline silicon wafers carrying a positive charge, alongside n-type crystalline silicon wafers bearing a negative charge. A notable distinction between n-type and p-type solar cells lies in the type of crystalline silicon (c-Si) wafers constituting the bulk region and those forming the slender emitter region.
