What Does SPV Stand For?

SPV stands for Surface Photovoltage

SPV, or Surface Photovoltage, refers to the electrical voltage generated at the surface of a semiconductor material when it is exposed to light. This phenomenon arises from the separation of charge carriers—electrons and holes—due to photogeneration upon light absorption. SPV is a crucial concept in the study of semiconductor properties and is often utilized in applications involving solar cells, sensors, and photodetectors, as it aids in understanding the efficiency and behavior of materials under illumination.
