Solar Panels: P-Type and N-Type: What You Need to Know

The distinction between P type and N type solar panels is one of the most frequently asked questions in the solar energy industry. Both of these solar cell types have a place in the history of solar technology, but they also have their own set of pros and cons. In this article, we’ll look at how P type and N type solar panels differ from one another, how they operate, and how businesses like CHINT are helping to create more effective solar energy systems.

How P Type and N Type Solar Panels Work

The core difference between P type and N type solar panels lies in how they are doped to create charge carriers. P-type panels have a bulk c-Si region doped with boron, which creates a positive charge. The top emitter layer is doped with phosphorus, giving it a negative charge. In contrast, N-type solar panels are doped with phosphorus in the bulk c-Si region, making them negatively charged, while their top emitter layer is doped with boron, giving it a positive charge. This fundamental difference affects their performance and longevity.

Advantages and Disadvantages of P Type vs. N Type Solar Panels

While P type and N type solar panels serve the same purpose, they have key differences in terms of performance and cost. N-type solar panels are gaining popularity because they are less susceptible to light-induced degradation (LID), offering a longer lifespan. However, they are generally more expensive than P-type panels. P-type panels, on the other hand, have been used extensively, particularly in space applications, and are more affordable for average homeowners. CHINT offers both P-type and N-type panels, such as the AstroSemi and AstroTwins, catering to various solar energy needs.

Conclusion

As a conclusion, before choosing a solar solution, it is vital to grasp the distinctions between P type and N type solar panels. Even though N-type panels are more long-lasting and efficient, P-type panels are still a popular and pocket-friendly choice. You can trust that CHINT’s AstroSemi and AstroTwins solar panels will provide you with the energy you need.
