“…The PL quenching phenomenon also confirmed the interaction between the AuNPs and the P3HT‐SH polymer. Because the Janus nanoparticles showed a higher PL quenching rate than the composite, the Janus structure is expected to increase the exciton dissociation efficiency in photovoltaic devices …”

A series of Janus composite poly(3-hexyl thiophene)-b-poly(3-thiophenehexanethiol)-gold nanoparticles were synthesized by self-assembly at the water-oil interface, and their photoelectric performance was investigated. The results show that the precise Janus composite nanostructure could be controlled by the adjustment of the reaction temperature and stirring time. The UV-visible measurement revealed that the absorption maximum had an appreciable redshift, and the photoluminescence (PL) spectra indicated that the PL intensity of poly(3-hexyl thiophene)-b-poly[3-(6-thiolhexyl thiophene)] decreased upon the addition of gold nanoparticles. In addition, compared to a common composite of poly(3-hexyl thiophene), the conductivity properties of the Janus composite nanostructure increased remarkably. Therefore, the Janus composite nanoparticles have the potential for applications in photovoltaic devices.

“…[9][10][11][12] The former contain nanocrystals (NCs) dispersed within a conjugated polymer matrix and have good potential for future application. 1,13 However, there are two key challenges that must be overcome to improve hybrid polymer solar cell power conversion efficiencies. 10,14 The rst challenge is to bypass residual (insulating) ligands that confer colloidal stability to the NC dispersions used for device fabrication.…”

“…This study focuses on P3HT/ ZnO photoactive lms (P3HT is poly(3-hexylthiophene)). We selected P3HT because it has been very widely studied in hybrid polymer/NC solar cells 1,13,27,28 and is used as a model conjugated polymer. ZnO NCs were primarily used in this study because they do not require long chain stabilising ligands for dispersion stability.…”

“…29 Furthermore, P3HT/ZnO lms are representative candidates for hybrid polymer solar cell construction because P3HT/ZnO solar cells have given efficiencies of 0.7 to 2.0%. 13,30 The approach used in this study is shown in Scheme 1A. Concentrated ZnO dispersions were stabilised by added 1-propylamine (1-PA, Scheme 1B) and mixed with P3HT solution containing added bilinker and then spin coated.…”

“…However, so far these hybrid devices do not achieve the same kind of power conversion as all organic photovoltaics. Different strategies have been applied to resolve the problem, such as by grafting P3HT chains onto the (DOPO-Br) functionalized CdSe surface [16], ligand exchange process of quantum dots with the branched oligothiophene dendrons [17], blending the nano particles with end functionalized conjugated polymers [18]. Among them, surface capping ligand play an important role by modulating the morphologies of two phases and, thus the efficiency of charge creation and transport.…”

This paper reports the synthesis of poly(3-hexylthiophene) (P3HT)/HA@ZnO nanocomposite by in situ polymerization and demonstrates their thermal, morphological and optoelectronic properties. Zinc oxide (ZnO) nanoparticles were prepared by the simple approach of coprecipitation method using zinc acetate dihydrate as precursor modified by hexamine (HA) acting as a capping agent.Structural and photo physical studies shows that conjugated polymer chains intimately contact with the inorganic semiconductor. ZnO has wurtzite structure with average crystallite size of 40 nm. The emission spectra indicate that modified ZnO nanoparticles results in more efficient photo induced charge transfer than that of the simple nanocomposite of P3HT/ZnO. The morphological studies revealed that the transformation of granular morphology of P3HT to the clusters in P3HT/HA@ZnO hybrid nanocomposites. Cyclic voltammeter elucidates the electrochemical behavior and the HOMO-LUMO energy levels of the nanocomposites. The results indicate that the P3HT/HA@ZnO nanocomposite has energy gap of 0.72 eV, indicating this composite has potential for the fabricating hybrid organic-inorganic solid state solar cells. A solar to electric energy conversion efficiency of 0.1238 % was attained with the system.
