PERC refers to a cell architecture, whereas P-type relates to the doping process of the silicon in the cells. PERC and standard P-type solar panels are both popular in the market, but PERC technology offers improved efficiency and performance due to advancements in solar cell architecture. In this article, we will do a deep and detailed analysis of what is a PERC solar panel, how it compares to older and other. PERC (passivated emitter rear contact) structure has a localised back surface field (BSF). BSF helps to improve the solar cell efficiency by forming a high-low junction with the p-type Si base wafer. Instead of being made from entirely new materials, PERC solar panels are essentially enhanced versions of conventional crystalline.
PERT (Passivated Emitter Rear Totally Diffused) cells also employ a passivation technique to improve cell performance. However, these cells feature a rear surface that is both passivated and diffused, which further enhances light trapping and absorption, leading to even higher efficiency than PERC panels.
First is a comparison between PERC and PERT panels as their names are so close. Both panel technologies were developed around the same time period, sharing similarities in their design concept. PERT (Passivated Emitter Rear Totally Diffused) cells also employ a passivation technique to improve cell performance.
What is PERC technology?
PERC is only one of the available technologies to improve efficiency and applications for solar panels. There are other advanced technologies like Interdigitated Back Contact (IBC) and Bifacial Solar Cell (BSC) technology. Manufacturers can use either one or even combine PERC with IBC or BSC.
PERC (passivated emitter rear contact) structure has a localised back surface field (BSF). The BSF is created from the doping of Al into Si during metal co-firing processes. BSF helps to improve the solar cell efficiency by forming a high-low junction with the p-type Si base wafer.
