Emerging nanotechnologies have revealed carbon nanotubes (CNTs) as one of the best materials with immense potential. Considering the outstanding physical, mechanical, electrochemical, thermal, and optoelectronic properties of CNTs, extensive studies have been reported assessing their applications in several disciplines. This paper presents a broad review of the studies in the literature that address the contribution of CNTs in terms of their applications as different parts of solar cells such as photoelectrode, photoconductor, top and back electrode, replacement of indium tin oxide (ITO) as transparent conducting electrode (TCE) in a variety of photovoltaics such as silicon, organic, polymer and dye-sensitized with their subsequent efficiencies.


Thin film (6,5) semiconducting single-walled carbon nanotube metamaterial absorber for photovoltaic applications
Obaidullah, Madina; Esat, Volkan; Sabah, Cumali (2017-12-01)
A wide-band (6,5) single-walled carbon nanotube metamaterial absorber design with near unity absorption in the visible and ultraviolet frequency regions for solar cell applications is proposed. The frequency response of the proposed design provides wide-band with a maximum of 99.2% absorption. The proposed design is also simulated with (5,4), (6,4), (7,5), (9,4), and (10,3) chiralities, and results are compared to show that the proposed design works best with (6,5) carbon nanotube (CNT) but also good for ot...
Three dimensional crystalline silicon solar cells
Baytemir, Gülsen; Turan, Raşit; Department of Physics (2018)
Three-dimensional crystalline silicon solar cells have been attracting attention with its remarkable electrical and optical performance. In this geometry, nano/micropillars allow minority carrier collection in the radial direction and shorten the path length of the photogenerated carriers. Furthermore, with appropriate geometry of the pillars the solar cell efficiency is enhanced due to the reduced surface reflectance and increased light harvesting. Throughout this study, metal assisted etching (MAE), a top...

Carbon nanotubes are allotropes of carbon with a cylindrical nanostructure. A nanotube can roughly be described as a rolled-up graphene sheet, which is a two dimensional hexagonal arrangement of carbon atoms, often referred to as a honeycomb lattice. Carbon nanotubes, much like their parent material graphene, are characterized by high strength, high Young modulus, durability and tunable electronic behavior. As a result of these superior properties, CNTs have been used in diverse technologically relevant app...
Titanium coverage on a single-wall carbon nanotube: Molecular dynamics simulations
Oymak, H; Erkoç, Şakir (2003-09-12)
The minimum energy structures of titanium covered finite-length C(8,0) singlewall carbon nanotubes (SWNT) have been investigated. We first parameterized an empirical potential energy function (PEF) for the CTi system. The PEF used in the calculations includes two- and three-body atomic interactions. Then, performing molecular dynamics simulations, we obtained the minimum-energy configurations for titanium covered SWNTs. The reported configurations include low and high coverage of Ti on SWNTs. We saw that on...
Single-walled carbon nanotube based metamaterial absorber for solar cell application
Obaidullah, Madina; Sabah, Cumali; Esat, Volkan; Sustainable Environment and Energy Systems (2017-6)
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 th...
