Why electrocaloric effect observed in ferroelectric polymers only?
Rk2112
Its not true that electrocaloric effect (ECE) is observed only in ferroelectric polymers. ECE can be found in any typical dielectric material. If polarization switches from one direction to the other upon application or withdrawl of electric filed, the temperature of the material changes. It happens both in organic as well as inorganic materials. It is found that the EC coefficent is high near ferroelectric phase transition temperature.

What is the meaning of Ferroelectric?
In physics the ferroelectric effect is an electrical phenomenon whereby certain materials may exhibit a spontaneous dipole moment, the direction of which can be switched between equivalent states by the application of an external electric field. Placing a ferroelectric material between two conductive plates creates a ferroelectric capacitor. Ferroelectric capacitors exhibit nonlinear properties and usually have very high dielectric constants. The fact that the internal electric dipoles can be forced to change their direction by the application of an external voltage gives rise to hysteresis in the "polarization vs voltage" property of the capacitor. In this case, polarization is defined as the total charge stored on the plates of the capacitor divided by the area of the plates. Hysteresis means memory and ferroelectric capacitors are used to make ferroelectric RAM for computers and RFID cards. Above retrieved from Answers.com Viper1

Can photoelectric effect be observed for all metals under same condition of incident light?
no , it cannot be observed in same conditions of incident light because, the threshold energy will be different for different metals.so in that particular threshold energy only the photoelectric effect for that metal can be observed.....
