Photovoltaic Properties Of ZnO Nanoparticle Based Solid Polymeric Photoelectrochemical Cells

Abstract

In this work, we report optical and photovoltaic properties of ZnO based solid polymeric photoelectrochemical (PEC) cell. In this device construction, film of ZnO nanoparticle (NP) has been sandwiched between ITO and LiClO 4 -PEO solid electrolyte. ZnO NP has been used as photo-anode and the electrolyte LiClO 4 has been dissolved in a solid solution polyethylene oxide that makes the device lightweight and portable. The charge transfer is performed by Li + and ClO 4 ions which serve the purpose of a redox couple in a conventional dye sensitize solar cell (DSSC). Short Circuit Current (J SC ) shows maximum when the ZnO/ITO interface has been illuminated by a UV light (350 ± 15 nm) passing through the transparent ITO glass substrate. J SC and Open Circuit Voltage (V OC ) of the best performing device are found to be 7 µA/cm 2 and 0.24 V respectively under white light of intensity 15 mW/cm 2 .

“…From the table, it was found that the J SC from this work is higher than that reported in [1,2,4,5], but smaller than that reported in [3]. This is because the conductivity of the electrolyte used in the PEC in this work is higher than those reported in [1,2,4,5], but smaller than that reported in [3].…”
