摘要：

A solar cell based on vertically aligned silicon p-i-n, core-shell-shell, nanowires interfacing with graphene film is proposed to exploit the benefits of short carrier collection lengths of radial p-i-n junction nanowires and transparency of graphene. A physical device model incorporated with optical characteristics taking into account all recombination processes is established to optimize its electrical performance by modifying nanowires density, filling ratio and thickness. Also; the dependence of the proposed structure to temperature variations and the number of graphene layers on its performance is investigated. (C) 2015 Elsevier B.V. All rights reserved.
