The addition of the PERC layer enables increased capture of light falling on the cell surface increasing the overall performance and efficiency.PERC technology works by reflecting back into the body of the cell any wavelengths of light that have passed through without generating electrons. This minimizes the recombination of atoms at the aluminum metallization layer, reducing the heat generated in the cell,
allowing it to work more efficiently. Through this, the cell will also be
able to absorb more infrared light (wavelengths of between 1000 and 1180 nm), increasing production in low light conditions and improving
overall energy yield (fig. 5).
