The introduction of donor-acceptor heterojunctions made small molecules and conjugated polymers attractive candidates for the fabrication of cost-efficient and flexible power sources. Polymer conductivity is key factor to improve the performance of the electronic and photonic devices. Poly(3, 4-ethylenedioxy thiophene): poly(styrenesulfonate) (PEDOT:PSS) is promising to be the next-generation transparent electrode of optoelectronic devices. In this research, we investigated the high efficiency of an OPV for which PEDOT:PSS and active layers were fabricated by spray deposition using the air brush coating method using various solvents like methanol, ethanol, acetone, acetonitrile, hydrochloric acid and sulphuric acid to form a hole transport layer (HTL). The surface morphology of the films deposited was examined using Atomic Force Microscopy (AFM). The current density(J)-voltage(V) characteristics were measured under the illumination of simulated solar light with 100 mW/cm2 (AM 1.5 G) by an oriel 1000 W soalr simulator. The obtained results show a considerable impact and bright future for organic polymer solar cells.
