Abstract

The microstructural, surface, optical and electrochemical impedance spectroscopic study of the all-solid-state thin film battery cell were done. Obtained results show that all deposited layers are in polycrystalline form. The crystallite sizes of the layers were calculated by Scherrer equation and its values were found in the range of approximately 10-30 nm. This shows that deposited layers are homogeneous. The fabricated battery is a semitransparent in visible region. According to reflectance graphs, total reflectance of the semitransparent all-solid-state is lower than the value of the un-coated glass substrate reflectance value. The capacity of the manufactured battery cell is approximately 8.3 mu Ah/cm(2). The highly reversibility of charging and discharging of the battery was obtained even after 100 cycles. Ultrahigh coulombic efficiency was obtained approximately 100%. It is concluded that the fabricated battery is proper for the optic and photovoltaic applications and also this battery is proper for the high power applications.
