Product Description

Advantages

The PERC PV module line has become a must-have for mainstream component manufacturers, with 1% or more efficiency higher than conventional components. While traditional photovoltaic cells have reached the limits of physical efficiency, this new PERC structure allows component manufacturers to increase the efficiency of component conversion. According to analysis, the market share of PERC components in the next three years will rise sharply and become a mainstream supply.

What are PERC solar cells?

PERC can stand for either Passivated Emitter and Rear Cell or Passivated Emitter and Rear Contact. At its core, a PERC solar cell is simply a more efficient solar cell, meaning that solar panels built with PERC cells can convert sunlight into usable electricity more easily. Solar panels made from PERC solar cells typically perform better than traditional panels in both low-light conditions and high temperatures. PERC technology boosts efficiency through the addition of a layer to the back of a traditional solar cell, which provides several benefits to the cell’s production. PERC solar cells are an exciting technology because of the efficiency gains they provide over standard solar cells. Additionally, moving to PERC manufacturing doesn’t require a lot of modifications to existing cell manufacturing processes. It’s a relatively easy shift for manufacturers to start producing higher efficiency PERC cells at a low cost.

How are PERC solar cells different from standard solar cells?

A PERC solar cell is not much different in construction from a typical photovoltaic solar cell. Both types of solar technology use silicon wafers to generate a flow of electrons using incoming solar radiation, and the overall construction of the cell types is very similar. The main difference between PERC cells and typical monocrystalline photovoltaic cells is the integration of a back surface passivation layer, which is a layer of material on the back of the cells that provides three main benefits that boost cell efficiency. How does a back surface passivation layer lead to gains in solar cell efficiency? Here are the three ways the passivation layer in a PERC solar cell increases overall efficiency:

1. Reflection of light back through the cell A back surface passivation layer reflects light that passes through the silicon cell without being absorbed back into the silicon, giving the solar cell a second absorption attempt. This reflection of light means that more incoming solar radiation will end up being absorbed by the silicon cell, thus the cell becomes more efficient. 2. Reduced electron recombination The addition of a back surface passivation layer reduces “electron recombination” in the solar cell. Simply put, electron recombination is the tendency of electrons to recombine, which causes a blockage in the free movement of electrons through the solar cell. This inhibition of free electron movement leads to less-than-optimal cell efficiencies. In a PERC solar cell, electron recombination is reduced in order to bump up efficiency. 3. Reduced heat absorption The third benefit from a PERC solar cell is the reflection of certain wavelengths of light. A silicon wafer in a solar cell can only absorb light in wavelengths up to 1180 nanometers (nm), and higher-wavelength light waves pass through the silicon and are absorbed by the solar panel’s metal back sheet, creating heat. When solar cells are heated, they operate at lower efficiencies. The back surface passivation layer in PERC solar cells is specially designed to reflect light with a wavelength above 1180 nm, reducing the heat energy in the solar cell and consequently increasing efficiency.
