Synthesis and photocurrent density–photovoltage (J–V) characterization of a novel alizarin derivative dye for dye-sensitized solar cell technology

Dye-sensitized solar cells technology has attracted extensive academic scholars’ interests due to their potential low-cost energy harvesting. Increasing performance of dye-sensitized cell needs more efficient dye maximize absorption. This work presents the synthesis and J–V characterization studies for a novel alizarin derivative HDD. The was formed by reaction between brominated 5-hexyl-2-thiopheneboronic acid pinacol ester. final product successfully synthesized as brownish-orange solid. Characterization done using spectroscopic techniques; mass spectrometry, infrared spectroscopy nuclear magnetic resonance before photovoltaic investigation. found be useful photo-sensitizer in through calculation conversion efficiency. Generally, HDD showed better results terms properties with open-circuit voltage, short-circuit current density fill factor 0.65 V, 0.0146 A/cm2 0.612, respectively. efficiency 5.81% under 100 mW/cm2 illuminations.
