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 re- sponses. An ionic liquid, ethyl-methylimidazolium dicyanamide, containing iodine I2 ,6 0 mM and tetrapropylammonium iodide TPAI, 500 mM has been employed as liquid electrolyte in photoelectrochemical solar cells based on polyterthiophenes contain- ing porphyrins with an overall conversion efficiency of 0.14% at a solar simulated light intensity of 500 W m 2
