Synthesis and Electrical Conductivity of N-(3-(Trifluoromethyl)Benzylidine)Thiosemicarbazide towards Dyes Sensitized Solar Cell

Abstract

Organic compound containing thiosemicarbazide moiety has been successfully synthesized. The new synthesized dyes, N-(3-(Trifluoromethylbenzaldehyde)benzylidine thiosemi- carbazide (3-TFT) was characterized by spectroscopic technique namely, CHNS elemental analysis, Fourier Transform Infra-Red analysis (FT-IR), UV-Visible analysis (UV-Vis),1H and13C Nuclear Magnetic Resonance (NMR). The thin films of this dye have been prepared using a spin coating technique and deposited on indium tin oxide (ITO) glass substrate. The main highlight was an electrical conductivity of thin films which was measured using four point probing system in a range of light intensity, 25 Wm-2until 200Wm-2. The potential electrical conductivity of 3-TFT dye was found gradually increased until reached the maximum conductivity values of 0.1489 Scm-1at light intensity of 100 Wm-2in the most diluted concentration at 1x10-5M.

Synthesis and Characterization of Natural Sensitizers for Dye Sensitized Solar Cells

“…Conventionally, solar cells semiconductor has the task of light absorption and the transportation of charge-carrier, whereby in the DSSCs, they are separately controlled [2]. The photosensitizing dye adsorbed on the nanocrystalline TiO2 semiconductor, absorbs light.…”
