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.
It is a layer of material providing three main benefits to boost efficiency. PERC technology can be used in all types of solar cell modules. PERC technology combines local rear contacts and rear wafer surface passivation to maximize the amount of light captured by solar panels. Thus, increasing the efficiency of the photovoltaic system.
Improved Low-Light and High-Heat Performance: PERC panels excel in low-light and high-temperature conditions, delivering approximately 3% higher efficiency. Superior Area Efficiency: Thanks to their increased efficiency, PERC panels can achieve the same power output as traditional panels using fewer units, reducing the installation space required.
Poly c-Si solar cells with 18.46% efficiency get an increased efficiency of 18.61% when manufactured with PERC technology, the difference is even more notorious with mono c-Si solar cells. A traditional mono c-Si panel has a 19.55% efficiency, but this efficiency increases by 0.86% to achieve 20.41% for mono PERC solar panels.
