Single-walled carbon nanotube based metamaterial absorber for solar cell application

Obaidullah, Madina
Carbon nanotubes possess superior mechanical and electrical properties such as being lightweight, strong, and flexible; and having high electrical conductivity. Solar cells containing single-walled carbon nanotubes that absorb photons near infrared region have been a focal area of research and development due to their promising characteristics of harvesting light in the long wavelength region, cost effectiveness and performance. Absorption properties of SWNTs are not yet well studied quantitatively, even though their importance is very significant for the new solar technologies. In this thesis, various SWNT based metamaterial absorbers with almost 99% absorption capability have been designed and numerically simulated for the solar cell application. The compact structure and maximum absorption of MTM absorber can provide highly efficient and cost effective solar cell. Novel wide-band, triple-band, and multi-band polarization-insensitive metamaterial absorber structure with semiconducting SWNT as the dielectric layer is proposed to efficiently absorb the incident electromagnetic radiations in a wide-range frequency region. Computed results are verified analytically by interface theory and also with the previously reported MTM absorbers available in the literature as well as with different solver techniques such as FEM and FIT.

Özel, Coşkun Kağan; Esat, Volkan; Sustainable Environment and Energy Systems (2019-8)
Carbon nanotubes (CNTs) attract significant attention being one of the superior engineering materials that possess exceptional material properties. One of the uses of carbon nanotubes is as reinforcements in a polymer matrix to form Carbon Nanotube Reinforced Polymer (CNTRP) composites. CNTRPs are lightweight structures with enhanced mechanical properties due to CNT addition. It is well known that CNTs do not usually exist in perfect structural form. They possess defects such as vacancies or Stone-Wales (SW...
Structural Vibration Analysis of Single Walled Carbon Nanotubes with Atom Vacancies
Dogan, Ibrahim Onur; Yazıcıoğlu, Yiğit (2014-11-01)
Recent investigations in nanotechnology show that carbon nanotubes have significant mechanical, electrical and optical properties. Interactions between those are also promising in both research and industrial fields. Those unique characteristics are mainly due to the atomistic structure of carbon nanotubes. In this paper, the structural effects of vacant atoms on single walled carbon nanotubes are investigated using matrix stiffness method. In order to use this technique, a linkage between structural mechan...

Dogru, Itir Bakis; Durukan, Mete Batuhan; Turel, Onur; Ünalan, Hüsnü Emrah (2016-06-01)
In this work, vertically aligned carbon nanotubes (VACNTs) grown on aluminum foils were used as flexible supercapacitor electrodes. Aluminum foils were used as readily available, cheap and conductive substrates, and VACNTs were grown directly on these foils through chemical vapor deposition (CVD) method. Solution based ultrasonic spray pyrolysis (USP) method was used for the deposition of the CNT catalyst. Direct growth of VACNTs on aluminum foils ruled out both the internal resistance of the supercapacitor...
