All of the following semiconductor devices are based on p-n junction EXCEPT
Correct answer: B. electrolytic cell
- A. photo diode
- B. electrolytic cell
- C. photo voltaic cell
- D. light emitting diode
Explanation
An electrolytic cell is not a semiconductor device and is not based on a p-n junction.

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
