What is a PERC solar cell?

If you have any questions, please contact us. Conventional silicon photovoltaic (PV) cells have long been the standard in the solar industry. But as the technology matures and approaches hard efficiency limits, researchers and manufacturers have started to embrace a relative newcomer — the Passivated Emitter and Rear Contact (PERC) solar cell.

How does PERC technology improve solar panel efficiency?

PERC technology boosts solar panel efficiency by solving two big problems found in traditional panels: surface recombination and light reflection. The extra layer on the back of the PERC solar cell reflects unused sunlight back into the panel, giving it another shot at generating energy.

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.

Are PERC solar panels a good choice?

There's a reason PERC cells are the industry standard — they're highly efficient and a much-improved type of PV technology compared to traditional solar panels. However, compared to the new development of N-type cells, there are some disadvantages.

Can bifacial PERC solar panels be combined?

The good news for the solar industry, is that bifacial and PERC technologies can be combined, to create bifacial PERC PV cells. These new and innovative solar cells can deliver up to 18% more power than monofacial solar cells. Understanding how PERC solar panel technology works, is key to understanding the pros and cons of different applications.
