About What is a PERC module
In this article, we will do a deep and detailed analysis of what is a PERC solar panel, how it compares to older and other advanced technologies, as well as the different applications for PERC solar panels.
Before diving into PERC solar panel technology and its benefits, it is important to have a proper understanding of traditional solar panels and how they work.
While the recombination of the e-h pair under the aforementioned circumstances is the regular process generating an electric current for traditional solar cells.
Since PERC is a technology implemented on traditional crystalline silicon solar cells, PV modules under this technology are divided between mono PERC solar.
PERC is only one of the available technologies to improve efficiency and applications for solar panels. There are other advanced technologies like Interdigitated.

6 FAQs about [What is a PERC module ]
What is PERC solar panel?
What Is the PERC Solar Panel? How Does It Work? PERC, which stands for Passivated Emitter and Rear Contact, is a type of solar panel technology designed to enhance the efficiency of traditional silicon panels.
What is PERC technology?
Other advanced panel technologies PERC is only one of the available technologies to improve efficiency and applications for solar panels. There are other advanced technologies like Interdigitated Back Contact (IBC) and Bifacial Solar Cell (BSC) technology. Manufacturers can use either one or even combine PERC with IBC or BSC.
What are PERC solar cells?
Key points on PERC cells: PERC solar cells are generally more efficient and resistant to heat than traditional silicon crystal cells. Using PERC cells in solar panels can increase their average efficiency from around 18% to over 21%. PERC solar cells are still subject to some of the same limitations as traditional solar cells.
How do PERC cells work?
To understand how PERC cells work, it’s important first to understand how traditional cells work. Traditional cells consist of a front contact on the face of the panel that receives sunlight, the n-type silicon layer below that, followed by the p-type silicon layer and the rear contact.
How do PERC panels work?
As a whole, the working principle of PERC panels involves several key elements. Firstly, incident sunlight strikes the front surface of the panel. The ARC manages to let the maximum amount of sunlight enter the cell.
What is the difference between PERC and IBC solar cells?
Efficiency for IBC solar cells is higher in general, but the highest recorded efficiency for both technologies is similar. The highest efficiency for PERC solar cells was recorded at 25.0%, while IBC solar cells achieved a 25.4% conversion efficiency. The biggest downside for IBC technology is that it has a higher cost than PERC solar panels.
