About Photovoltaic solar panel PERC
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. Traditional solar panels are called monocrystalline and polycrystalline silicon solar panels, depending on their manufacturing materials.
While the recombination of the e-h pair under the aforementioned circumstances is the regular process generating an electric current for traditional solar cells, there is also another type of recombination called surface.
Since PERC is a technology implemented on traditional crystalline silicon solar cells, PV modules under this technology are divided between mono PERC solar panels and poly PERC solar.
Understanding how PERC solar panel technology works, is key to understanding the pros and cons of different applications. In this section, we.

6 FAQs about [Photovoltaic solar panel PERC]
What is a PERC solar cell (or photovoltaic cell)?
PERC (PPassivated Emitter and Rear Cell), the passivated emitter and back cell technology, was first proposed by Australian scientist Martin Green in 1983 and is now becoming a new generation of conventional technology for solar cells.
What are PERC solar panels?
One option that outstands from the rest is the Passivated Emitter and Rear Contact (PERC) solar technology which allows for the creation of PERC solar panels. The PERC solar panel is a highly efficient and improved type of PV technology that uses Crystalline Silicon (c-Si) and fixes some inconveniences of this traditional technology.
How efficient are PERC solar cells?
The maximum efficiency of PERC cells is about 23%, compared to about 21% for traditional monocrystalline silicon cells. The diagram below shows a cross section of a PERC solar cell built into a module. These are the layers, from top to bottom:
What are the pros and cons of PERC solar panels?
Passivated Emitter and Rear Contact (PERC) technology is an excellent improvement that allows solar cells to achieve higher efficiencies. While this technology presented several cons in the past like LID and PID, manufacturers found ways to solve this, resulting in high-efficiency PERC solar panels without the cons of the technology in the 80s.
Are PERC solar panels the future?
Really anywhere that space is constrained or power production needs to be maximized, PERC solar panels can fit the bill. While dominant now, some even more advanced solar technologies are emerging that may eventually dethrone PERC cells. But they have yet to totally unseat PERC panels in the marketplace.
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.
