Organic-inorganic hybrid material: synthesis, characterization for solar cell application

Abstract

We report a hybrid system based on conducting polymer-semiconductor from poly(otoluidine) (POT) doped with camphor sulfonic acid(CSA) and cadmium selenide capped with Tri sodium citrate(CdSe-TSC) by the physical mixing method. The influence of CdSe nanoparticles weight percent on the hybrid thin films have been investigated by means of XRD, FESEM, UV-VIS absorption and photoluminescence spectroscopy (PL) measurements. The main diffraction peaks of POT/CdSe hybrids are analogous to the neat CdSe nanoparticles. The absorption measurement reveals that the interaction between CdSe and POT in the hybrid materials led to the blue shift and broadening of the polaron absorption band. The energy gap has been decreased with an increase in the concentration of CdSe NPs. the PL intensity has been totaly quenched when the tow materials are bring to other. The hybrid nanocomposite material and provides useful evidence apropos the optimum use of CdSe nanoparticles in conductive polymer based optoelectronics.

Critical Review on Interrelationship of Electro-Devices in PV Solar Systems with Their Evolution and Future Prospects for MPPT Applications

“…So far, organic nanomaterials (i.e., graphene and carbon nanotubes) have been shown to be highly compatible with any solar cell of previous generations, leading to the intensive development of hybrid organic-inorganic nanocomposites for PV solar cells in recent years. [102,103]. Graphene, by definition, is a two-dimensional substance with a single layer of graphite, in which carbon atoms are organized into a hexagonal honeycomb lattice.…”

Study the Optical and Morphological Properties of Prepared PANI/TiO₂ Nanocomposites

“…Additional to the easiness of production and reduced costs, they are known to have mild poisoning effects, which makes them an attractive alternative. In practical applications, Polyaniline is one of the most important types of conductive polymers for several reasons and features that make it this position like its outstanding ecological stabilities, ease of production, great temperatures resistance, and remarkable electric conductivities with diverse kinds and dopant concentration [1][2][3][4]. Inorganic materials such as Iron oxide Fe2O3, titanium oxide TiO2, manganese oxide MnO2, Tin oxide SnO2, and other similar materials are combined with conducting polymers to improve their properties in the application of optoelectronics, catalytic properties, antimicrobial activities, water treatment and storage applications, among other things etc.…”

Synthesis of PVA-Fe2O3-TiO2 hybrid structure for biomedical application

“…Polymer based composite nanomaterials are of tremendous scientific and technological interest because of their unique optical, electrical, and mechanical capabilities. A wide variety of uses exist for these materials, including optoelectronic components and magneto-optic data storages [7][8][9]. Many efforts have been made to enhance the optical properties of polymer nanobased composites by reinforcing polymers with metal, semiconductor, carbon nanotubes, and magnetic nanoparticles [10][11][12][13][14][15][16].…”
