In this paper we propose a conceptual Photovoltaic device that comprises a large number of vertically aligned single-walled carbon nanotubes (SWCNT) having distinct geometrical structure properties. Through employing analytical models of the CNT, we demonstrate how this structural variation can be exploited in absorbing a broadband of the solar spectra. The results show that given a group of CNTs...
In the following paper we present a complete analytical model that predicts the band-gap (Eg) of single-walled carbon nanotubes (SWCNTs) directly from their diameter (d) and chiral angle (thetas). The proposed analytical model is based on two mathematical expressions that have been derived by curve-fitting the outcome generated from the third-nearest-neighbor tight-binding (TB) method in conjunction...
