Investigation of Electrodeposited Nano ZnO as a Photoanode for Dye-Sensitized Solar Cell (DSSC)

Theerawut Sumphao, Nattee Khottummee


This paper reports the deposition and characterization of nanoporous zinc oxide (ZnO) by using a simple and low-cost electrodeposition method. SEM, XRD and UV-Vis are used to study the structural, morphology, and optical properties of ZnO thin films. ZnO has a nanosheet-like structure that is 1 m in size. The optical energy band gap shifts from 3.44 eV to 3.46 eV after the dying process. The organic dye of Clitoria ternatea was extracted and used as a synthesizer. An anthocyanin peak is observed in the absorption spectrum. The zinc oxide films are employed as photoanodes on dye-sensitized solar cells (DSSCs). The I-V characteristic curve parameters show a PCE of 0.027% and a fill factor of 38%.
