Abstract

New experimental results of morphological and optical properties of Curcuma longa dye thin film were investigated. The thin films were deposited by physical vapor deposition technique. Morphological properties were measured using atomic force microscopy technique and they show a granular structure which above there are nanotubes shapes. Photoluminescence of Curcuma longa at low temperature was investigated and discussed for the first time. The temperature effect from 77 to 300 K of Curcuma longa thin film has been shown and luminescence was strongly observed. Photoelectrochemical parameters of the dye-sensitized solar cell based on Curcuma longa have been computed via the finite element method. The power conversion efficiency is about 0.86% obtained from short circuit current, open-circuit voltage, and fill factor of 0.13 mA/cm2, 0.52 mV, and 0.83, respectively. As a result, Curcuma longa dye can be applied to dye-sensitized solar cells.
