WebResponsivity is the ratio of photocurrent generated from incident light, to that incident light power. This is usually expressed in units of A/W (current over power). A typical responsivity curve of a photodiode will show A/W as a function of wavelength. WebDefinition : The responsivity of silicon photodiode is a measure of sensitivity to light. It is defined as ratio of photocurrent (I p) to incident light power P at given wavelength. Responsivity, R λ = I p /P. In other words, it is measure …
