N-Type VS P-Type Solar Panels

Solar energy is becoming increasingly popular not simply because it brings down energy bills, but because it creates your home a more self-sustainable home.

When you decide to install the best Solar Power System in Brisbane, it is important to check its technical aspects first.

Solar panels are the most important and fundamental part of the whole system. They are available in two different types.

• N-Type
• P-Type

Once you know the difference between the two, it will help you to best determine which one fits your specific needs and budget. Let’s understand them.

Structure of a Solar Cell

The construction of a solar cell will slightly vary depending on the specific technology utilized to manufacture it.

Typically, in solar cells, there is an aluminum back surface field and a P-N Junction.

On this P-N junction, there are crystalline silicon wafers.

The p-type wafers are positively charged, and the n-type crystalline silicon wafers are negatively charged.

One of the biggest differences between these two types of solar cells is what type of crystalline silicon (c-Si) wafers make up the bulk area and what types of wafers make up the thinner emitter region.

Both of these wafers work together to create an internal electric field inside the solar cell. This field generates energy.

N-Type Solar Panels

When there is an n-type solar panel, the bulk c-si region is charged negatively. It is because these wafers are doped with phosphorus.

The top layer of the wafer is top emitter layer of negative charge because it is doped in boron.

N-type solar panels have gained popularity because they are not as susceptible to light-induced degradation as P-type solar panels are.

These N-type solar panels can be installed in all types of setups, and they have a longer lifespan. However, they do cost more than the conventional P-type panels.

You can find these Solar Panels in Brisbane in many installations.

P-Type Solar Panels

P-type solar panels have a bulk c-si region prominently. This layer is negatively charged because it is doped in boron.

The top emitter layer of P-type solar panels is positively charged because it is doped with phosphorus.

P-type solar panels are more popular today. This is because they have gone under more research than the N-type panels.

Which one should you choose?

When you call the Best Solar Installers in Brisbane, they will perform a detailed analysis of your power generation needs first.

As far as the comparison of their performance and efficiency, the N-type solar panels do stand out slightly better than their counter parts. With an efficiency level of 25.7%, they are superior to the 23.6%efficiency of P-type panels.

P-type panels are dipped in boron, therefore when they interact with oxygen in the air the performance of the panel drops by up to 10% overtime. When they are used for residential use, they can be slightly less effective than n-type panels.

The life of n-type solar panels is longer than p-type solar panels.

Pricewise, p-type panels are cheaper.

So, let the solar panel experts decide which type of panels are ideal for your home.
