Abstract

This study compares two charge storage nanoparticles (CdS and AgPt) in organic storage devices. The charge elements are embedded in an active conductive polymeric layer composed of poly vinyl alcohol (PVA) and poly acrylic acid (PAA) doped with glycerol. The size distribution of the synthesized particles was characterized using SEM and Zeta analyzer. Capacitance–voltage measurements of the fabricated storage devices revealed hysteresis loop with large window gates indicating their charge storage capacity. Centimeter-scale micro wind turbine is used to generate charge to be stored in the storage devices and to determine their storage characteristics and time constants. The results showed that the semiconductive charge storage CdS discharges 23% faster than the conductive bimetallic AgPt.
