Hi,
I am working on fabrication of ZnO UV photodiodes. I wish to know the exact formula for the calculation of External Quantum Efficiency (EQE) of UV photodiodes.
With Photoresponsivity (R), in some papers, it is mentioned as,
EQE = 1240 x (R/λ)
while in some papers, it is mentioned it as,
EQE = 1240 x (R/λ) x 100%.
Where 'R' is Photoresponsivity and λ in the wavelength of incident light)
Can you please clarify me which of the above-mentioned formulae is correct?and whether we have to multiply the EQE value with 100%?
Kindly support with some literature for your answers
Thanks in advance.
