Abstract

Abstract Studies on HSCs have been focussing on exploration of natural dyes obtained from Eugenia claviflora (EC). This work mainly aimed to enhance device efficiencies related to new dye sensitizer particularly Eugenia claviflora. These samples were then characterised based on morphology, thickness, optical absorption, electrical conductivity and solar cell’s performance in term of efficiency, voltage and current using various techniques including FESEM, EDS, profilometer, UV-Vis, FTIR and autolab with irradiance of 100 mW/m2. TiO2/PEDOT:PSS/ EC obtained an open – circuit voltage (Voc) of 0.43 V with fill factor of 0.2 leading to an efficiency of 1.33%. The absorption of TiO2/PEDOT:PSS/EC was located at 550 nm (between 450 nm to 755 nm) which exhibited an intense broad band in visible light. Hence, fabrication of HSCs was successful thus improving its’ performance.
