Abstract
A copolymer of 5,15-bis22:5,2-terthiophen-3-yl-2,8,12,18-tetra-n-butyl-3,7,13,17-tetramethylporphyrin with 2,2:52-terthiophene was successfully electrosynthesized by cyclic voltammetry, galvanostatic, and potentiostaic methods. This conducting copolymer was then incorporated into photovoltaic devices using liquid electrolyte and tested for photovoltaic responses. An ionic liquid, ethyl-methylimidazolium dicyanamide, containing iodine I2, 60 mM and tetrapropylammonium iodide TPAI, 500 mM has been employed as liquid electrolyte in photoelectrochemical solar cells based on polyterthiophenes containing porphyrins with an overall conversion efficiency of 0.14% at a solar simulated light intensity of 500 W m−2.
