“…[3,4] Consequently, this material has been widely studied for different applications in many domains such as electrochromic devices, rechargeable batteries, protection of metals against corrosion, [5,6] organic light emitting diodes (OLEDs), [7,8] organic photovoltaic cells (OPVs) [9] and dyesensitized solar cells (DSSCs). [10][11][12] Its reversible redox chemistry allows PANI to have mainly three distinguishable oxidation states.…”

“…Since PEDOT itself obtained by chemical polymerization is insoluble black powder, thus mixing of PSS is essential to make PEDOT soluble and conducting . Electrochemical deposition of PEDOT film and its derivatives on ITO substrate as HTL has been reported for photovoltaic device fabrication, while the PCE is lower and studies have been limited . Despite the significant efforts, however, there remains a clear need for the development of new, robust and solution‐processable HTL for cost effective photovoltaic devices and in plastic optoelectronics more generally.…”

We first time report poly(styrene sulfonate) (PSS) free poly(3,4ethylenedioxythiophene) (PEDOT) as a novel solution-processable hole transport layer (HTL) for organic solar cells. The transparent and conducting PEDOT thin film was obtained by solid state polymerization (SSP) of 2,5-dibromo-3,4-ethylenedioxythiophene (DBEDOT) on ITO coated glass substrate (by heating of the monomer at 60 8C for overnight). The thicknesses of the obtained thin films were optimized by using different concentrations of DBEDOT in chlorobenzene during spin coating. Two different combinations of active layers such as poly(3-hexylthiophene):phenyl-C 61 -butyric acid methyl ester (P3HT:PC 61 BM) and poly[N-9'-heptadecanyl-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)]:phenyl-C 71 -butyric acid methyl ester (PCDTBT:PC 71 BM) were used for device fabrication. Power conversion efficiencies were achieved up to 0.71 % and 1.70 % in a simple geometry of ITO/ssp-PEDOT/active layer/Al under ambient conditions. The potential importances of the ssp-PEDOT as an HTL are robust, stable, PSS free and solution-processable for organic solar cells.

“…PAni is one of the most extensively studied conducting polymers due to its easy synthesis, high conductivity, environmental stability and reversible redox catalytic properties [8][9][10][11][12][13][14][15] . The metal nanoparticles, such as Pt, on PAni modified electrode show catalytic properties for organic fuel oxidation [16][17][18][19] . Fuel cells are known as one of the best electrical power to obtain the electrical energy from the combustion of hydrogen or organic compounds, than other sources [20][21][22] .…”

In this research, we reported the electrosynthesis of platinum nanoparticles on Polyaniline (PAni) modified electrode. The modified electrodes were prepared by incorporation of aniline and platinum salt [H 2 (PtCl 6 ), 6H 2 O] in phosphoric acid medium with KCl solution on composite graphite (CG) surface via cyclic voltammetry (CV) method. The synthesized platinum nanoparticles were characterized by using scanning electronic microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The electro oxidation of methanol was investigated at the surface of these modified electrodes using CV method. It was found that methanol was oxidized with platinum embedded on the surface of PAni modified electrodes during the anodic potential sweep. Moreover, several impact factors such as scan rate, potential and concentration of methanol were studied on the oxidation of methanol toward electrosynthesized electrodes.
