All PV cells have both positive and negative layers — it''s the interaction between the two layers that makes the photovoltaic effect work. What distinguishes an N-Type vs. P-Type solar cell is whether the dominant carrier of electricity is positive or negative. N-Type PV cells contain atoms with one more electron than silicon in the outer layer
An anti-reflection-coating is coated on the solar cells as well as the front glass of the photovoltaic modules to enhance the cell performance. The photovoltaic module also has an anti-soiling coating to suppress the power generation loss owing to soiling during exposure at the installed site.
