Water-soluble multiwall-carbon-nanotube-polythiophene composite for bilayer photovoltaics

چکیده
A water-soluble acid oxidized multiwall carbon nanotube o-MWCNTs -polythiophene composite for bilayer photovoltaics is reported. Discrete heterojunction photovoltaic cells utilizing this nanocomposite material as the donor layer exhibit a 20% increase in fill factor and commensurate increase in power conversion efficiency as compared to cells without o-MWCNTs. Crucially o-MWCNTs are incorporated into the cell structure using an environmentally compatible solvent without complicating the process of device fabrication. © 2006 American Institute of Physics.

Different types of crystalline carbon nanomaterials were used to reinforce polyaniline for use in electromechanical bilayer bending actuators. The objective is to analyze how the different graphitic structures of the nanocarbons affect and improve the in situ polymerized polyaniline composites and their subsequent actuator behavior. The nanocarbons investigated were multiwalled carbon nanotubes...
متن کاملLoad Transfer Issues in the Tensile and Compressive Behavior of Multiwall Carbon Nanotubes
Carbon nanotubes (CNT) are considered to be ultra strong and stiff reinforcements for structural composite applications. The load transfer between the inner and outer nanotubes in multiwall carbon nanotubes (MWCNT) has to be clearly understood to realize their potential in not only composites, but also other applications such as nano-springs and nano-bearings. In this paper, we study the load t...
متن کاملAn Improvement in Thermal and Rheological Properties of Water-based Drilling Fluids Using Multiwall Carbon Nanotube (MWCNT)
Designing drilling fluids for drilling in deep gas reservoirs and geothermal wells is a major challenge. Cooling drilling fluids and preparing stable mud with high thermal conductivity are of great concern. Drilling nanofluids, i.e. a low fraction of carbon nanotube (CNT) well dispersed in mud, may enhance the mixture thermal conductivity compared to the base fluids. Thus, they are potentially ...

We report the performance of polythiophene/fullerene solar cells with a hole-collecting buffer layer that was made using composite films of functionalized multi-walled carbon nanotube (f-MWCNT) and poly(3,4ethylenedioxythiphene):poly(styrenesulfonate) (PEDOT:PSS). The MWCNT was functionalized with carboxyl groups to bestow solubility in a weak base solvent for mixing with PEDOT:PSS. Results sho...
