Amphiphilic gold nanoparticles have been synthesized and employed for improving the performance of polymer optoelectronics devices. Such nanocomposites could be readily incoporated into the buffer and/or photoactive layers, resulting in obvious enhancements in device efficiencies.
We have improved the device performance of polymer photovoltaic devices (OPVs) by blending Au nanoparticles (NPs) into the anodic buffer layer. The unique optical properties of localized surface plasmon resonance (LSPR), triggered by Au NPs, was beneficial for improving the photocurrent of OPVs. The excitation of LSPR increased not only the exciton generation rate but also the exciton dissociation...
Organic thin-film transistors with a minimal threshold voltage shift and a more stable photocurrent under illuminated conditions can be made by embedding titanium dioxide (TiO 2 ) nanoparticles into a polymer dielectric layer. While the studies of pentacene morphology using atomic force microscopy and X-ray diffraction have shown similar results before and after embedding the TiO 2 ...
High performance organic thin-film transistors (OTFTs) incorporated with high dielectric nanoparticles in the dielectric layers have been demonstrated. The dielectric insulator consists of cross-linked poly-4-vinylphenol (PVP) and titanium dioxide (TiO 2 ) nanoparticles. In order to obtain highly soluble TiO 2 nanoparticles in organic solutions, the surface of nanoparticles was modified...
