impact of Sheet Resistance on 2 d modeling of thin film solar cells
Solar Energy Materials and Solar Cells, 2009Co-Authors: Galymzhan T Koishiyev, J R SitesAbstract:Abstract A rigorous mathematical approach was used to find a relation between the transparent-conductive-oxide (TCO) Sheet Resistance ρ S (Ω/□) of a thin-film solar cell and the parameter R (Ω) that describes the TCO Resistance in a two-dimensional circuit model. Additionally, the mathematical relationship that connects experimentally derived series Resistance R S (Ω cm 2 ) of the solar cell to the TCO Sheet Resistance ρ S (Ω/□) and the bulk semiconductor resistivity ρ (Ω cm) was derived. It was found that the fill factor of the solar cell is governed by a reduced dimensionless TCO Sheet Resistance that depends only weakly on the type and quality of the solar cell. Parameters corresponding to thin-film Cu(In,Ga)Se 2 , two-junction a-Si, and an ideal solar cell were used as concrete examples.

carbon nanotube polyurethane films with high transparency low Sheet Resistance and strong adhesion for antistatic application
RSC Advances, 2017Co-Authors: Ying Tian, Xingcai Zhang, Hongzhang Geng, Haijie Yang, Jie Wang, Songlin JiaAbstract:Antistatic technology has been applied in all aspects of modern life, including the manufacture of electronic products, aerospace systems, daily necessities and so on. The main purpose of this study is to obtain, using the Mayer rod-coating method, a flexible antistatic film with high transmittance, low Sheet Resistance and strong adhesion. With the help of the dispersant, single-walled carbon nanotubes (SWCNTs) were dispersed in water to form an homogeneous dispersion. The SWCNT dispersion was coated onto a poly(ethylene terephthalate) (PET) film with use of a rod to produce a uniform film. The antistatic films obtained had special characteristics, such as high transparency, low Sheet Resistance and excellent Resistance to water and heat. Sheet Resistance varied between 102–105 Ω sq−1 by controlling the content of water-based polyurethane (WPU), changing the thickness of the films and the post-treatment. The best film had a Sheet Resistance of 423 Ω sq−1 with 82.7% transmittance. In particular, the addition of the WPU binder greatly improved the adhesion between the CNTs and the PET film. Scanning electron microscopy, energy dispersive X-ray spectroscopy and Scotch™ tape method were conducted to determine the microstructure, cleanliness, and adhesion of the film, respectively.
