About What is PERC in photovoltaic modules
Understanding how PERC solar panel technology works, is key to understanding the pros and cons of different applications. In this section, we round up the major pros and cons of PERC solar panel technology and highlight some of its best features.
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.What is passivated emitter rear cell (PERC) solar technology? PERC is a high-efficiency solar technology. It adds a dielectric layer to silicon cells. This layer reflects light and reduces recombination. The result is better light trapping and higher power conversion efficiency (PCE).

6 FAQs about [What is PERC in photovoltaic modules ]
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 can PERC technology improve solar panel efficiency?
One of the most recent introductions to increase solar panel efficiency has been the development of a new industrial process of advanced passivated emitter and rear cell (PERC) technology. The introduction of PERC technology has increased solar efficiency, which translates to faster ROI and more savings for end users.
What are PERC photovoltaic cells?
It adds a dielectric layer to silicon cells. This layer reflects light and reduces recombination. The result is better light trapping and higher power conversion efficiency (PCE). In effect, panels outfitted with PERC photovoltaic cells generate more energy than traditional panels of the same size under the same conditions.
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.
Which solar panels can use PERC cells?
Both can use PERC cells, and these are known as mono PERC and poly PERC. Mono PERC offers the highest performance, while poly PERC is a cost-effective upgrade over traditional polycrystalline panels. Traditional monocrystalline and polycrystalline solar cells are made with a layered construction that includes the following components:
Why should a solar PV installer use perc?
As a result, solar PV installers are able to save time and reduce costs when using the newer PERC standard. This is because fewer panels are needed to achieve the same solar power output. Using fewer panels also helps to reduce the amount of racking, wiring, and MLPE devices needed to connect everything together.
