Photodiodes Vietnam Accurate Light Detection Components

Photodiodes are semiconductor devices that convert light into electrical current. When exposed to light (photons), they generate a current proportional to the light intensity—a process known as the photovoltaic effect. Photodiodes are essential components in light detection and optical sensing systems. They are typically designed to operate in reverse bias, where the current generated is directly related to the amount of incident light, offering fast and accurate light sensing capabilities.
