Role of Layer‐by‐Layer Deposition on Electrical and Optical Properties of PEDOT: PSS/Polyaniline Thin Films for Solar Cells

In this article, electrical and optical properties of PEDOT:PSS/Polyaniline: (PANI)bilayer thin films deposited on indium tin oxide (ITO) are reported. Spin coater has been used for fabrication of thin films of 40–50 nm thickness at 5000 rpm. The deposited thin films have been characterized by using...

Description
Summary:In this article, electrical and optical properties of PEDOT:PSS/Polyaniline: (PANI)bilayer thin films deposited on indium tin oxide (ITO) are reported. Spin coater has been used for fabrication of thin films of 40–50 nm thickness at 5000 rpm. The deposited thin films have been characterized by using Fourier transform infrared (FT‐IR) spectroscopy, scanning electron microscopy (SEM), UV‐vis spectroscopy and Keithley electrometer. Layer‐by‐layer (LBL) technique has been shown to produce electroactive polymer films with low roughness, excellent uniformity, and high electrical conductivity for heterojunction solar cells. The electrical response of fabricated films showing ohmic behavior for PEDOT: PSS/PANI thin films.
