How Photoelectric Effect Impacts p-n Junctions
When light strikes a semiconductor p-n junction, its energy is absorbed by electrons. Electrons and holes generated by light in the p-n junction are swept by the junction electrical field. Consequently, the current flows through the junction. The figure below … Read more

How the Photoelectric Effect Influences Semiconductors
A photoelectric effect is any effect in which light energy is converted to electricity. When light strikes certain light-sensitive materials, it may cause them to give electrons or change their ability to conduct electricity or may cause them to develop … Read more
