What are the different uses of Silicon PIN Photodiodes?
PIN photodiodes are a type of photodiode that has an undoped region (referred to as the intrinsic layer) sandwiched between p- and n-doped regions. In these devices, the photons are absorbed by the intrinsic layer, which in turn creates an electric current induced by the action of light, known as the photocurrent. Silicon PIN photodiodes (Si PIN) are a specific type of semiconductor photodiode whose intrinsic layer is made from silicon. As a semiconductor, silicon PIN photodiodes have a higher sensitivity to low-spectrum light, such as UV light, while having faster response times and lower noise. These qualities are best applied in such applications as optical communication systems, industrial inspection components, medical and scientific instruments and environmental monitoring.
