Phototransistors are semiconductor devices that convert light energy into electrical signals. They consist of a semiconductor junction and a transparent window that allows light to enter and interact with the semiconductor material. Phototransistors amplify the current generated by incident light, making them suitable for applications requiring high sensitivity to light levels, such as optical encoders, ambient light sensing, and infrared remote control systems.
