Technical FAQs 4

What are PERC cells?

PERC (Passivated Emitter and Rear Cell) cells are a high-efficiency type of P-type cell. Their production process is more streamlined compared to other types of cells, resulting in excellent cost control. They mainly employ BSF (Back Surface Field) and PERC technology routes.

How does PERC technology work?

When solar cells are heated, they operate at lower efficiencies. PERC technology actually increases the cell’s ability to reflect longer wavelengths by introducing the di-electric passivation layer at the rear.

What are PERC solar panels?

This is where PERC panels come in handy. “PERC” stands for “Passivated Emitter and Rear Cell” or “Passivated Emitter and Rear Contact.” They are different from standard solar cells in the extra layer found on the back that you won’t find on your traditional cell.

What is PERC (passivated emitter & rear cell)?

For broader reference on PV technology basics, see the DOE’s Solar Energy topic hub and the EIA for market data. PERC (Passivated Emitter and Rear Cell) improved on BSF cells with rear‑side passivation. You get mature supply, low upfront cost, and wide inverter compatibility. Typical traits:
