What are the advantages of PERC technology?

A PERC cell (Passivated Emitter Rear Cell) incorporates a reflective layer on the back, between the silicon and the aluminium. Thanks to this technique, part of the radiation is reflected on the silicon layer and does not pass through the solar panel. With this reflection, the cell absorbs more energy and can also dissipate temperature better, thus achieving higher thermal efficiency than other classic PV cell technologies, as heat is an enemy of a solar panel's performance.
