Abstract

Abstract: The past few decades Dye-Sensitized Solar Cells (DSSC) based on TiO2 nanoparticle have attracted much attention from researchers because of their promising Physico-chemical properties and high photoconversion efficiency. In this research, TiO2 nanoparticles mediated with hexamethylenetetramine surfactant were successfully synthesized by the hydrolysis method. The influence of hexamethylenetetramine surfactant precursor concentration on DSSC photovoltaic performance was investigated. The prepared samples are characterized by field emission scanning electron microscopy, X-ray diffraction, and UV–vis absorption spectroscopy. SEM analysis results show that the HMT surfactant has a big influence on the morphology, particle size, and crystal phase of TiO2 particles. The surface morphology exhibited the nanorice grain particles in all samples. By spectrophotometry, it was shown that the films had a bandgap of about 2.9 eV. The film promoted by HMT 0.3 M from DSSC showed a power conversion efficiency of 1.7%.
