How does PERC technology improve performance?
PERC technology increases the overall panel performance by increasing
a cell’s ability to capture light. A regular solar cell consists of two layers
of silicon with different electrical properties – known as the base and meet, which pulls negatively charged particles(electrons) into the light entering the cell and releasing electrons from the silicon atoms. Electrons travel freely through the cell and contribute to the electrical current only if they are able to reach the interface (fig. 2).
