Due to very low ionisation enthalpy values.

alkali metals generally of lower periods is more photoelectric because of their large atomic radii.when the atomic radii of an element increases the elecrons in the outermost shell of the atom is not strongly held by the nucleus.so when light of sufficient frequency falls on it the electron is exicted.therefore they are photoelectric.
