What is PERC & how does it work?

This game-changer is known as PERC. It means Passivated Emitter and Rear Contact. This technology has a special layer that stops electrons from recombining. It also reflects unused light back into the cell for more power. So, PERC isn’t just jargon. It’s a symbol of higher efficiency and better performance in solar panels.

What does PERC stand for?

PERC stands for Passivated Emitter and Rear Cell technology. Depending on where you look, you may also see it referenced as Passive Emitter and Rear Contact . Although the technology itself has existed since the mid-1980s, it only started to be utilized at the research level more recently.

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 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.

What is the difference between PERC and Pert cells?

PERT (Passivated Emitter Rear Totally Diffused) cells also employ a passivation technique to improve cell performance. However, these cells feature a rear surface that is both passivated and diffused, which further enhances light trapping and absorption, leading to even higher efficiency than PERC panels.

What is PERC cell technology?

2. What is it? PERC cell technology defines a solar cell architecture that differs from the standard cell architecture that has been in use for three decades and that is usually featured in all photovoltaic manuals. As of today, the vast majority of crystalline solar cells produced follow the structure presented hereunder.
