Exam-style question
Try this first
Which factor primarily affects the efficiency of a photodiode?.
- A.The temperature of the diode.
- B.The wavelength of the incident light.
- C.The size of the photodiode.
- D.The type of semiconductor material used.
Model answer
What a good answer should say
- The wavelength of the incident light.
Explanation
Why this works
The efficiency of a photodiode is influenced by the wavelength of the incident light, as different wavelengths can generate varying amounts of photocurrent depending on the material's bandgap.
