The answer lies in PERC technology - a revolutionary cell architecture that''s transforming photovoltaic performance. PERC (Passivated Emitter and Rear Cell) technology boosts solar efficiency by adding a rear passivation layer, reducing electron recombination and increasing light absorption to achieve 22-24% efficiency in commercial panels.
Passivated emitter and rear cell (PERC) technology can significantly increase the absolute efficiency of PV cells by over 1.2%. Since PERC processing is also compatible with current cell processing, and does not incur overly high manufacturing costs, many PV manufacturers are focusing on developing the industrialization technologies for PERC cells.
PERC solar cells in TongWei’s main efficiency band were used in the standard 60-cell modules, resulting in over 300W per module on average. SolarWorld and Trina Solar have both reported cell conversion efficiencies above 22% for their industrialized screen-printed PERC solar cells.
The secret lies in its sophisticated rear-side design that maximizes every photon''s potential. PERC cells feature a dielectric passivation layer on the rear surface that reflects unused light back into the cell while reducing electron recombination, combining with laser-doped contacts to optimize current collection.
