Definitions for "Phototransistor"
It is a transistor which amplifies current induced by photoconductivity.
An optoelectronic device that conducts current when exposed to light. Produces more current and is much more sensitive to light than the photodiode.
a bipolar transistor used as a photodetector
a type of photosensor. Typically used where speed of response is important or ambient temperature variations are great.
a type of photovoltaic cell
