Abstract:

With the aim of studying the use of conjugated polymers poly(3- methylthiophene) (P3MT), poly(3-hexylthiophene) (P3HT) and polydiphenylamine (PDPA) to make up the active layer of inverted organic solar cells forming the interface with TiO2, and also help shed light on the optical and electronic properties applied to develop this technology, the interfaces between films containing P3MT, P3HT and PDPA on ITO electrode were electrochemically prepared, after chemically depositing a film of TiO2. The systems under investigation were designated ITO/TiO2/P3MT, ITO/TiO2/PDPA/P3MT, ITO/TiO2/PDPA, ITO/T

Abstract:

Aim: This project aims to improve the electrical characteristics in the polymer tandem solar cell by changing polymers with thickness to increase the efficiency. Methods and Materials: The PEDOT: PSS and P3HT Polymer was chosen as a group having 20 samples in each respectively. The electrical characteristics are stimulated by varying the polymer with thickness. Changing the polymer material leads to improved efficiency in the tandem solar cell. Results: The Independent T test was done which reveals that the P3HT (P = 0.553) was found to be statistically significantly compared with PEDOT: PSS p

Abstract:

In this work, we investigate the morphology and microstructure of the aggregates, and the gelation behaviour of Poly(3-hexylthiophene) (P3HT) conjugated polymer in xylene solution as functions of P3HT concentration and aging time by the means of ageing time test, wide angle X-ray diffraction (WAXD), scanning electron microscopy (SEM), UV-visible absorption (UV-vis) and photoluminescence (PL) spectra. The result reveals that the gelation time of P3HT/xylene solution decreases markedly with increasing P3HT concentration. The photophysical properties of the P3HT aggregates in P3HT/xylene solution

Abstract:

Poly(3-hexylthiophene) (P3HT) is a semiconductor polymer that has been proved to be a good electron donor in organic or hybrid solar cells. In this work, a detailed study of P3HT synthesis in CH2Cl2solvent by oxidative method with and without MW assistance has been conducted. Effects of synthesis process parameters on the physical properties of P3HT products and their application in hybrid CdS/P3HT photovoltaic devices were studied. It is observed that the use of MW as well as the reaction time affected the reaction yield and properties of the polymer products. It was found that, by the tradit

Abstract:

In this paper, new polymers for use in organic photovoltaics were investigated. PPBI, PNBI and copolymer MULT are considered as a potential alternative or an effective dopant for P3HT and PCBM. The choice of these materials allows us to find out new information on the prospects and properties of heterocyclic polymers — for thermal stability and resistance to the environment for organic solar cells. The levels of HOMO and LUMO of new heterocyclic polymers were measured, and the results were compared with those of P3HT: PCBM. The level of new polymer MULT photoluminescence was determined. The ab

Abstract:

A novel film preparation method utilizing polymer suspension, entitled adsorbing deposition in suspensions (ADS), has been proposed. The poly(3-hexylthiophene) (P3HT) toluene solution forms P3HT nanofibrils dispersed suspension by aging. P3HT nanofibrils are highly crystallized with sharp vibronic absorption spectra. By the ADS method, only P3HT nanofibrils in suspension can be deposited on the substrate surface without any disordered fraction from the dissolved P3HT in suspension. Formed ADS film contains only the nanostructured conjugated polymer. Fabricated polymer thin-film transistor (TFT

Abstract:

Aligned polymer nanofibres are prepared by means of the electrospinning of a chlorobenzene solution containing regioregular poly(3-hexyltiophene-2,5-diyl), P3HT, and poly(ethylene oxide), PEO. The PEO scaffold is easily dissolved with acetonitrile, leaving pure P3HT fibres, which do not show structural modification. Polymer fibres, either with or without the PEO supporting polymer, are effectively doped by exposure to iodine vapours. Doping is monitored following the changes in the doping-induced vibrational bands (IRAVs) observed in the infrared spectra and by means of Raman spectroscopy. Mol

Abstract:

Organic field-effect transistor (OFET) gas sensors based on conjugated polymer films have recently attracted considerable attention for use in environmental monitoring applications. However, the existing devices are limited by their poor sensing performance for gas analytes. This drawback is attributed to the low charge transport in and the limited charge–analyte interaction of the conjugated polymers. Herein, we demonstrate that the incorporation of graphitic carbon nitride (g-C₃N₄) into the conjugated polymer matrix can improve the sensing performance of OFET gas sensors. Moreover, the effec

Abstract:

An excitation energy transfer in a bulk heterojunction based on freestanding silicon nanocrystals (Si-NCs) and conjugated polymers {poly(3-hexylthiophene) (P3HT), poly[2-methoxy-5-(2-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV)} is demonstrated. The electrochemical etching process is employed for fabrication of freestanding and polymer soluble Si-NCs. Formation of a bulk heterojunction is confirmed by a difference in a work function of both polymers and an ionization potential of the NCs. An annealing step significantly influences the polymer chain conformation and electronic interaction

Abstract:

Composite films of conjugated polymers, such as poly[2-methoxy-5-(3′,7′-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMO-PPV) and poly(3-hexylthiophene) (P3HT), with C60nanowhiskers (C60NWs) were prepared. The photoluminescence originating from the conjugated MDMO-PPV polymers was effectively quenched in the composite film, indicating a strong interaction between the conjugated polymer and C60NWs. The photovoltaic devices were fabricated using C60NW (conjugated polymer) composite films, resulting in a power conversion efficiency of ~0.01% for P3HT with short length thin C60NWs, which is higher t
