What Is N-Type Technology in Solar Panels: explained

Among the many new and cutting-edge technologies that the solar energy industry in Pakistan has been offering to consumers, solar panels seem to always boast the latest and greatest in whatever new frontiers the research and development sectors in the renewable energy segment bring forth. Whether its bifacial solar panels or N-type technology that a lot of the best solar energy equipment suppliers in Pakistan like ZNC Solar are offering to consumers, solar panels make up the most important part of a solar energy solution; it is befitting, therefore, that a bulk of the R&D bucks go towards solar panels.

In this blog post, we will look at the aforementioned N-type technology, and we’ll discuss what is it all about. From the basics of N-type, to the panels that actually have it, and how ZNC Solar is bringing forth the best of solar energy equipment technology to consumers in Pakistan, this is everything you need to know about N-type technology in solar panels. Lets get started.

N-type technology for solar panels

One of the more recent developments and testament to the ever-so-evolving nature of research and development in the solar energy industry is the N-type technology panel, which leverages some pretty amazing technology to ensure the top-notch quality, generation metrics and efficiency numbers, promising consumers the best when it comes to solar panel performance. So, what is N-type technology for solar panels? Let’s get right into it.

N-type technology refers to the usage of silicon wafers in photovoltaic cells. These silicon wafers are doped with phosphorus, which provides the entire PV cell with a negative charge, giving the entire panel a host of improvements over your regular, run-of-the-mill solar panel. Unlike some other technologies, like the P-type panels, which use boron for doping, these panels are much more better. How so? Lets take a look, but before that, lets understand doping and what doping means in the solar energy industry.

Doping solar cells

A solar panel, basically, is a collection of thousands upon thousands of solar cells, all wrapped together to form a panel. These solar cells are what generate energy, doing so using the photovoltaic principle, which utilises heat and not actual sunlight to knock off electrons from the element inside, forming a current. In advanced technologies, these wafers, made out of silicon, are doped or essentially coated with other elements to give them a positive or negative charge; usually a negative charge is preferred, since it would mean that the efficiency of the solar panel would be improved. So, for N-type panels, the cells are doped with phosphorus, that gives the solar cells a negative charge, allowing them to be much more efficient. But just how efficient? Lets take a look at why doping with phosphorus allows N-type solar panels to outperform their regular brethren.

N-type solar panels: the benefits

What makes the N-type solar panels such a big hit among consumers, both residential and commercial? Lets take a look at the many benefits of the N-type solar panel and how it is better than your regular, run-of-the-mill solar panel.

i. Better efficiency

N-type solar cells are usually much more efficient than their P-type counterparts or your regular solar panels. This is primarily because of a process called light-induced degradation or LID, which affects solar panels, and whose effects aren’t necessarily too obvious for N-type solar panels. With fewer defects in silicon, less energy is lost as heat with the N-type panel.

ii. More durable

When compared to P-type solar panels, N-type panels outperform in durability tests, once again thanks to their phosphorus doping, which makes them much more tolerant of extreme or high temperatures that solar panels are regularly exposed to.

iii. Better linear performance

N-type solar panels also perform better than their P-type solar panels over time, allowing for much better linear performance over time, where other solar panels may simply degrade over time.
