Electrochemical and optical properties of the polymers were analyzed. The fabrication of solar cells were carried out and current density-voltage (J-V) and incident photon to charge carrier efficiency (IPCE) measurements were done to characterize the solar cells.

Electrochemical polymerization of para-substituted haloanilines
Cihaner, A; Önal, Ahmet Muhtar (Informa UK Limited, 2006-01-01)
Polyhaloanilines: poly(4-fluoroaniline) (P4FAN), poly(4-chloroaniline) (P4CAN), and poly(4-bromoaniline) (P4BAN), are synthesized from para-substituted haloaniline monomers; 4-fluoroaniline (4FAN), 4-chloroaniline (4CAN), and 4-bromoaniline (4BAN), respectively, via constant potential electrolysis (CPE) in acetonitrile-water mixture (1:1 v/v) with NaClO4 as supporting electrolyte. Prior to CPE, electrochemical behavior of the monomers were investigated in organic medium utilizing cyclic voltammetry (CV). Th...
