perc solar cell

Best answer


PERC is a technology which is used to improve the efficiency of solar cells by capturing as many extra photons as possible without fundamentally changing how a solar cell works. In ordinary crystalline silicon solar cells, electricity is produced when photons hit a layer of silicon, knocking electrons loose and then directed to flow along a wire.

  • What are PERC solar panels?

  • PERC solar cells are modified conventional cells that enable the cells to produce 6 to 12 percent more energy than conventional solar panels. PERC solar cells have an extra layer within the back side of the cell. This allows some of the sun’s rays to reflect back into the solar cell, giving them another opportunity to be turned into energy.

  • What is PERC cell technology?

  • PERC cell technology explained. 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.

  • What is the difference between PERC solar cells and monocrystalline solar cells?

  • The main difference between PERC solar cells and monocrystalline photovoltaic cells is the additional passivation layer on the backside of the solar cell. This layer is what increases the panel’s energy generation by boosting efficiency. Wondering how does a PERC solar cell work to improve efficiency?

  • What is the mass production efficiency of PERC solar cell?

  • At present, the mass production efficiency of the leading single crystal PERC solar cell can reach 21.5%, and the mass production efficiency of polycrystalline PERC can reach 19.7%.
