PERC photovoltaic module conversion rate

The PERC structure can break through the physical efficiency achieved by traditional photovoltaic cells and enable photovoltaic module manufacturers to improve module conversion efficiency.

This is a more significant boost than it may sound like at first. As a result of this improved efficiency, PERC solar cells can increase the solar panel efficiency —or, the amount of sunlight converted to energy—from around 18% to 21%. PERC boosts efficiency through two mechanisms:

PERC solar cells are the main technical contributors to the solar cell efficiency record that has been broken again and again. In the first half of 2018, the PERC solar cell efficiency was recorded at 23.95%, which was created by Jinko on May 9, 2018.

Key points on PERC cells: PERC solar cells are generally more efficient and resistant to heat than traditional silicon crystal cells. Using PERC cells in solar panels can increase their average efficiency from around 18% to over 21%. PERC solar cells are still subject to some of the same limitations as traditional solar cells.

In today's development trend, the audience of PERC cells in the photovoltaic market has become overwhelming. The production line of PERC photovoltaic modules has almost become a must-have for mainstream module manufacturers, with an efficiency 1% or more higher than traditional modules.

At present, PERC technology has become the main method for increasing the efficiency of P-type solar cells, but the performance of PERC technology on polycrystalline and monocrystalline cells is different.
