There are two main types of solar cells used in photovoltaic solar panels – N-type and P-type. N-type solar cells are made from N-type silicon, while P-type solar cells use P-type silicon. While both generate electricity when exposed to sunlight, N-type and P-type solar cells have some key differences in how they are designed and perform.
You''ve probably seen solar panels on rooftops all around your neighborhood, but do you know how they actually work to generate electricity? In this article, we''ll take a look at photovoltaic (PV) solar cells, or solar cells, which are electronic devices that generate electricity when exposed to photons, or particles of light—this conversion is called the photovoltaic effect.

The electrons move along the concentration gradient. This works as a battery wherein phosphorus doped silicon is negative terminal and the other part is positive terminal. The moving electrons and holes thus produce electric current. A solar cell consists of a p-type layer of silicone next to an n-type silicon layer (Fig. 1). The n-type layer
Semi-Conductors used in Photovoltaic Cells. One dopant material used is phosphorus. Phosphorus has five electrons in its outer shell. What happens when a phosphorus atom joins the crystalline structure with silicon, is that one electron in its outer shell cannot pair with a silicon atom and is therefore left free.
But ultimately, all photovoltaic cells perform the same function. A photovoltaic cell harvests photons from sunlight and uses the photovoltaic effect to convert solar power into direct current electricity. The photovoltaic cells contained in a PV module transmit DC electricity to an on-grid, off-grid, or hybrid solar system.
Many different companies use many different materials to manufacture many different types of photovoltaic cells and modules — like solar panels. But ultimately, all photovoltaic cells perform the same function. A photovoltaic cell harvests photons from sunlight and uses the photovoltaic effect to convert solar power into direct current electricity.
The vast majority of photovoltaic cells used in modules like solar panels in residential PV systems are made from crystalline silicon nonmechanical semiconductive material. Regardless of what they're made from (or for), semiconductors function by conducting electricity under specific conditions.
Phosphorus has five electrons in its outer energy level, not four. It bonds with its silicon neighbor atoms, but one electron is not involved in bonding. Instead, it is free to move inside the silicon structure. A solar cell consists of a layer of p-type silicon placed next to a layer of n-type silicon (Fig. 1).
The most commonly used type of photovoltaic cells by far are made primarily from crystalline silicon. Amorphous silicon can also be used to manufacture thin-film solar cells, but using pure monocrystalline or polycrystalline has multiple advantages — including much higher efficiency.
