P-Type vs N-Type Solar Panels

What is The Difference Between an N-type and P-type Cell?

The main difference between p-type and n-type solar cells is the number of electrons. A p-type cell usually dopes its silicon wafer with boron, which has one less electron than silicon (making the cell positively charged). An n-type cell is doped with phosphorus, which has one more electron than silicon (making the cell negatively charged).

N-type cells are resistant to light induced degradation due to the presence of phosphorus instead of boron within the silicon. This immunity leads to a longer carrier lifetime of the cell and a more efficient, powerful system. N-type cells are also less prone to metallic impurities that affect P-type cells and have a higher temperature tolerance.
