Photoelectrical refers to the properties of materials or phenomena related to the interaction between light and electricity. Synonyms for photoelectrical include photovoltaic, photoconductive, photodiode, photoelectric, and phototransistor. Photovoltaic refers specifically to the conversion of light into electricity, while photoconductive pertains to materials that increase their electrical conductivity in response to light. Photodiode is a semiconductor device that allows current to flow in one direction in response to light, while photoelectricity describes the emission of electrons from a material upon exposure to light. Finally, phototransistors are bipolar transistors that convert light signals into electrical signals. These terms are commonly used in the fields of electronics, optics, and renewable energy.
