उत्तर
The metal mainly used in devising photoelectric cells is Cs.
Explanation:
The photoelectric effect is the phenomenon of electron ejection from metal surfaces when electromagnetic radiations are directed at them. When exposed to light, alkali metals, particularly potassium, and caesium, eject electrons due to their low ionisation enthalpies.
