In this paper, we report surface dielectric and photodielectric properties of polyester sheet for photo cell application under standard conditions (t=22 ⁰C and RH=60%). At 750 Hz surface dielectric conductanse and susceptanse of polyester have been found and respectively. We were found increase of conductance and susceptance with increasing of frequency. The results showed that there were pronounced contact relaxation effects at interface between alumina electrode and sample, which falls by about 60% from its initial value about 10 min after beginning of the experiment carried out in the dark. Furthermore, the surface dielectric conductance and susceptance of polyester sample increased during UV-Vis radiation. The temperature coefficients of conductance (TCCG) and susceptance (TCCB) of the polyester sample at various frequencies were also studied.
