Hybrid heterojunctions of Polyaniline/Amorphous Silicon (PAni / a-Si:H) were synthesized in order to fabricate the active layer of the polymeric solar cells. For this purpose, amorphous silicon nanoparticles were blended with polyaniline which was synthesized through oxidative polymerization. Then the resultant nanocomposite was applied on FTO in the FTO/ZnO/PANI:a-Si/Ag structure using the spin coating method. The effect of amorphous silicon content on light-harvesting efficiency was studied using the UV-VIS spectroscopy data, electrochemical impedance spectroscopy (EIS), and the incident photon to current efficiency (IPCE) analysis. PAni / a-Si:H nanocomposites were characterized structurally and morphologically using Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), and X-ray diffraction (XRD) analysis. Current-Voltage measurements of the photovoltaic cells based on PAni / a-Si:H nanocomposites showed that by increasing the amount of a-Si:H in the active layer by 40 Wt%, the efficiency of the cell increases up to 2k times compared to the cell made with pure PAni. Also, in general, cell efficiencies increased slightly with decreasing the size of amorphous silicon nanoparticles at a constant PAni / a-Si:H weight ratio. The impact of a-Si:H weight percent is more significant in the case of smaller silicon particles.

“…In order to reach better SWCNTs dispersion in the polymeric matrix, a lower SWCNTs weight concentration is often added. This weak concentration greatly leads to improving the photovoltaic power conversion efficiencies [10] due to the charge transfer occurring at the heteronano-junctions. Moreover, SWCNTs are known by a good factor form (ratio: Length/diameter  500) and higher hole and electron mobilities, allowing them the properties of a good transporting layer [11].…”

We present a comparative experimental and theoretical study of the vibrational, optical, and electronic properties of polyaniline at both emeraladine leuco-emeraldine forms and PVK. Our objective is first to select the appropriate form of PANI to be linked with PVK to form a hybrid polymer matrix. Then, on the basis of quantum chemical calculations, we present a theoretical study of a hybrid composite PANI/PVK functionalized with lower radius (5, 5) chiral single-walled carbon nanotubes (SWCNTs). The relationship structure-properties of the resulting nano-composite are proved based on the conformational and optical study made from Density functional theory (DFT) and time-dependent density functional theory (TD-DFT) using B3LYP method with 6-31-G(d) basis set. First, it has been demonstrated that the resulting interaction between PANI and PVK leads to more advantageous properties, such as good optical absorption compatibility with the solar emission spectrum. It has also been found that after the incorporation of SWCNTs into the matrix of PANI/PVK hybrid polymer, a good organization of SWCNTs via π-staking interaction is imposed by polyaniline sequences. However, PVK moieties are grafted on the sidewalls of SWCNTs. Finally, the electronic structure of the resulting hybrid nano-composite PANI/PVK/SWCNTs was carried out with the use of different electrodes on both sides.

In this work, the one-pot process was employed to synthesize polyaniline/cadmium sulfide hybrid nanocomposite. Herein, for the first time, we report a comprehensive study from the synthesis of the raw materials to the photovoltaic cell performance investigation including the synthesis of the polyaniline/cadmium sulfide hybrid nanocomposite through a one-pot process, a morphology study, the fabrication of a hybrid organic/inorganic solar cell, and the evaluation of the cell performance. To this end, the CdS-to-PANI weight ratio was considered as a key parameter, and 0, 2.5, 5, 10, 15, 20, and 40% were used as the CdS values. FTIR, XRD, and FESEM analyses confirmed that the presence of CdS in the PANI nanotubular network affected the morphology of the hybrid nanocomposite, and changing the CdS-to-PANI ratio tuned the nanotubular network morphology from coarse to fine. UV–visible absorption spectrum studies validated the reduction of PANI bandgap due to the presence of CdS. Likewise, the conductivity of the nanocomposites was also improved compared to neat PANI due to the increasing of charge density. These controlled-morphology nanocomposites were used for organic/inorganic hybrid solar cells based on the configuration of the FTO/ZnO/CdS@PANI/Ag device, and the morphology effects on their performance were investigated. When CdS was incorporated in the PANI nanotubular network, J SC and efficiency increased by, respectively, 4.471 mA·cm–1 and 1.87%. This means a 22-fold increase in J SC and a 1700-fold increase in the solar cell based on 20%CdS@PANI compared to those in the solar cell made with pure PANI. In short, by using the one-pot process, it is possible to hierarchically ensure better control of the morphology of organic and inorganic components, increasing the light absorption edge, reducing the bandgap, and improving the photovoltaic performance of CdS@PANI organic–inorganic hybrid nanocomposites.
