How to Evaluate Responsivity of Photodetector?

Responsivity of Photodetector evaluator uses Responsivity of Photodetector = Photocurrent/Incident Power to evaluate the Responsivity of Photodetector, Responsivity of Photodetector refers to a measure of their sensitivity to incident light or radiation. It quantifies how efficiently a device converts incoming optical or electromagnetic radiation into an electrical response. Responsivity is typically expressed in units of Amperes per Watt (A/W) and represents the photocurrent generated per unit of incident optical power. Responsivity of Photodetector is denoted by R symbol.
