PERC stands for Photoelectric Effect Research Center, a facility dedicated to studying the photoelectric effect, which is the phenomenon where electrons are emitted from a material when it absorbs light. This research is crucial for developing technologies like solar cells and photodetectors, which convert light into electrical energy. The center collaborates with scientists and engineers to explore new materials and methods to enhance the efficiency of devices that rely on the photoelectric effect. By advancing our understanding of this effect, PERC aims to contribute to innovations in renewable energy and improve the performance of electronic devices.
