“…A high density CNTs film will lead to lower sheet resistance but will also result in lower transmittance. [91] The resistance of the CNT networks comes from the contact resistance between the overlapping CNTs and the resistance of the CNTs themselves depending on the CNT length, diameter, the ratio of metallic and semiconducting CNTs (M/S ratios), synthesis method and the purity of the CNTs. In addition, rough surface of the CNTs film is another major concern for its application as flexible BTE in the flexible OSCs, which may lead to significant shunt resistance losses.…”

Flexible and semitransparent organic solar cells (OSCs) have been regarded as the most promising photovoltaic devices for the application of OSCs in wearable energy resources and building‐integrated photovoltaics. Therefore, the flexible and semitransparent OSCs have developed rapidly in recent years through the synergistic efforts in developing novel flexible bottom or top transparent electrodes, designing and synthesizing high performance photoactive layer and low temperature processed electrode buffer layer materials, and device architecture engineering. To date, the highest power conversion efficiencies have reached over 10% of the flexible OSCs and 7.7% with average visible transmittance of 37% for the semitransparent OSCs. Here, a comprehensive overview of recent research progresses and perspectives on the related materials and devices of the flexible and semitransparent OSCs is provided.

“…Other important features of SWCNTs are mechanical strength and high elasticity [21,22]. Those properties determined SWCNTs utilization for applications in rigid [23][24][25] and flexible transparent electronics [26][27][28][29] as well as in optoelectronics [30][31][32]. Transparency, great electrical properties, and inherent nanometer size of SWCNT have motivated the interest to the SWCNT plasmonics.…”

Midinfrared Surface Plasmons in Carbon Nanotube Plasmonic Metasurface

We report an experimental observation of the midinfrared surface plasmon excited in a carbon nanotube plasmonic metasurface. The absorption of a 400-nm-thick single-walled carbon nanotube film perforated with laser-drilled subwavelength holes arranged in a 2D lattice is resonantly enhanced by 75% as compared with the unstructured film. The enhancement of absorption has a resonant behavior associated with the excitation of the surface plasmon and occurs at the wavelengths around 15 μm for the lattice period of 10 μm. The spectral position and the magnitude of the resonance are controlled entirely by the structure geometry and can be tuned in a broad range. We demonstrate that periodic patterning can be applied to tailor the bolometric performance of carbon nanotube thin films. Namely, the voltage response of the metasurface is enhanced by 100% at the wavelength of the plasmon resonance as compared with the unstructured film. We discuss mechanisms of the enhancement and compare experimental results with the finite-difference time-domain and scattering-matrix method simulations.

“…This property can be very useful for applications such as chemical sensors [5], gas storage [6], optical limiter [7], field transistor [8], solar cell [9], organic light-emitting diodes [10][11][12], etc. Several methods have been successfully developed to treat CNTs by introducing impurities inside the tube or on the surface in an effort to change the electrical properties of CNTs.…”

This paper proposes a novel chemo-mechanical method to in-situ functionalize carbon nanotubes (CNTs). Ball milling in the presence of ammonium bicarbonate allowed the introduction of amine and amide groups onto the surface of CNTs, resulting in the conversion of the semiconducting behavior of CNTs from p-type to n-type. The corresponding electrical conductivity of CNT increased gradually with ball milling time, presenting a remarkable 250% increase after 9 hrs of milling. These interesting observations are attributed to the nitrogen compounds introduced on CNTs, which function as the electron donor in the material.
