Question

Statement I: Photovoltaic devices convert optical radiation into electrical energy. Statement II: Zener diode operates in breakdown under reverse bias. Select the correct option.

G1 Physics · Accepted Answer

Photovoltaic devices (e.g. solar cells) create emf using photogenerated electron–hole pairs, so Statement I is true. A Zener diode is designed to operate in reverse breakdown at a controlled Zener voltage, so Statement II is also true. Final answer: Option C.
