what is pde ?
in terms of the formula , and in general so i can picture it in my mind so to speak.

Photodetection efficiency (PDE) is a measure of how well a photodetector converts incident light into an electrical signal. It represents the percentage of photons that are detected and converted into electrical current.
PDE is calculated by dividing the number of photoelectrons produced by a photodetector by the number of incident photons. It is typically expressed as a percentage or a decimal between 0 and 1.
There are several factors that can affect PDE, including the material and design of the photodetector, the wavelength of the incident light, the temperature, and any external noise or interference.
PDE is an important parameter for photodetectors because it indicates how sensitive a detector is to light. A higher PDE means that a detector can detect and convert more photons into electrical signals, making it more efficient and accurate.
PDE can be improved by using materials with higher quantum efficiency, optimizing the design of the photodetector, minimizing external noise, and using filters to match the wavelength of the incident light to the detector's sensitivity.
