The fundamental distinction between P-type and N-type solar cells is the number of electrons. A P-type cell often dopes its silicon wafer with boron, which has one fewer electron than silicon (forming the cell positively charged). An N-type cell is doped with phosphorus, which contains one extra electron than silicon (making the cell negatively

Customer ServiceOne of the recurring research themes in the field of crystalline silicon photovoltaics is the question of which absorber dopant type should be preferred: n- or p-type.

Customer ServiceN-type Si (silicon) solar cell materials have extremely low boron content, and the light-induced degradation effects caused by boron-oxygen pairs can be largely disregarded. Consequently, N-type Si solar cells possess a longer minority carrier lifetime compared to P-type Si solar cells. These advantages result in N-type Si solar cells having a longer lifespan and higher efficiency.

Customer ServiceThe difference between p-type and n-type crystalline solar cells The raw material that precedes the the pulling and cutting of silicon wafers is the same for both p and n-type cells. This raw silicon feedstock is “grown” into ingots ( Czochralski process) or cast as bricks and then thinly sliced. These wafers form the basis of a solar cell.
A standard crystalline silicon (c-Si) solar cell is a silicon wafer that has been doped with various chemicals to promote power output. The fundamental distinction between P-type and N-type solar cells is the number of electrons.
Monocrystalline p-type solar modules use cells/wafers that are Czochralski-grown (and block cast p-type polycrystalline cells/wafers to a lesser extent) suffer from light induced degradation (LID). LID occurs when oxygen impurities in the silicon wafer react with the doped boron in the first few hours/weeks of illumination of the cell.
It turns out p-type Si is far more resistant to the degradation from cosmic array. This demand set the tone of the industry and p-type Si solar cells came to dominate the residential and commercial solar markets globally. Recently, however, n-type cells have begun to accumulate market share due to their efficiency and manufacturing benefits.
Panasonic n-type cells are composed of monocrystalline and amorphous silicon layers. Amorphous silicon layers in the cells prevent recombinations of electrons, minimizing power loss. Why consider using module with n-type cells
In an N-type cell, electrons are the majority charge carrier. They flow from the N-type layer on top to the metal contact, generating electricity. In a P-type cell, the absence of electrons (holes) are the majority charge carrier. They flow from the P-type base to the N-type emitter.
