N-Type vs. P-Type Solar Panels

 

The choice of solar panel plays an important role in determining its efficiency, durability, and performance. Two popular types of solar panels often mentioned are solar power units of N and P. Let’s explore what is N-type and P-type solar panels, how they work, and their advantages and disadvantages.

Working Of A Solar Cell

Before getting into the specifics of N-Type and P-Type solar panels, it is important to understand the basic functions of solar cells. Solar cells are the heart of solar panels and are responsible for converting sunlight into electricity.

They work based on the photoelectric effect, which produces electricity when materials are exposed to sunlight. Solar cells are generally made of semiconductor materials with properties that allow them to absorb photons and release electrons.

What are N-Type Solar Panels?

N-type solar panels, also known as N-type crystalline silicon solar panels. It gained attention due to its efficiency. These frames are made from a designed silicon wafer.

In N-type solar panels, group V elements of the periodic table, such as phosphorus, are incorporated into the silicon wafer. The addition of these elements creates an excess of electrons in the silicon structure, making it negatively charged. This negatively charged element is known as N-element. On the other side of the wafer, a positively charged P-layer due to the incorporation of Group III materials such as boron.

What are P-Type Solar Panels?

P-type solar panels, also known as P-type crystalline silicon solar panels. It is a more traditional and widely used option. While they are generally efficient, especially in optimal conditions. They can experience more significant efficiency losses in high-temperature environments or when shaded.

The border or intersection of these two lines is where magic happens. When sunlight strikes the N-type layer, it releases electrons into the P-type layer to generate electricity. This flow of electrons is what we capture P-type in N-type solar panels.
