Step-by-step solution

Zener diode is heavily doped and designed to operate under reverse bias in the breakdown region. Solar cell generates emf when solar radiation falls on the p-n junction, and it operates with no external bias. Photodiode is operated under reverse bias (below breakdown) to detect optical signals because the fractional change in minority carrier current is easily measurable. Light emitting diode (LED) is a heavily doped p-n junction which operates under forward bias to emit spontaneous radiation. Thus, the correct mat
