A photoconductive cell is a type of semiconductor device that changes its electrical conductivity when exposed to light. It is often used in light sensors, photodiodes, and solar cells. However, there are several other synonyms that can also be used to describe this type of device. These include photoresistor, photoconductor, and optocell. Each of these terms refers to a device that changes its conductivity in response to light. Although these terms may be used interchangeably, it is important to understand the specific attributes and features of each device in order to choose the appropriate type for specific applications.
