How do you calculate quantum efficiency of photodiode?
The quantum efficiency of a photodiode is calculated by determining the ratio of the number of electrons generated to the number of incident photons. This calculation often involves factors like the wavelength of the incident light and the photoresponsivity of the photodiode. The quantum efficiency provides a measure of the effectiveness of the photodiode in converting light into electrical current. For detailed methodologies and formulas, it’s best to refer to technical resources or scientific publications related to photodiode technology.
The formula for the quantum efficiency (QE) of a photodiode is typically represented as:
This formula calculates QE as a percentage, reflecting the efficiency with which the photodiode converts incoming light (photons) into an electrical signal (electrons). The specific calculation may vary based on additional factors like the photodiode’s characteristics and the wavelength of the incident light.
Figure It is the quantum efficiency/ external quantum efficiency curves of different photodiode/ photodetectors from UV-VIS to NIR wavelength range tested by Enlitechās PD-QE system.The EQE is shown as a percentage, indicating the efficiency with which each device converts incoming photons into an electrical signal at different wavelengths. This graph is useful for comparing the performance of these devices across the spectrum of light they can detect. The different peaks and troughs of the curves give insight into which wavelengths each device is most sensitive to, which is crucial for their application in various fields such as spectroscopy, optical communications, or photovoltaics.
