Optical and electrical modeling of solar cells based on graphene/Si nanowires with radial p–i–n junctions

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 radial p–i–n junction and transparency graphene. physical device model incorporated optical characteristics taking into account all recombination processes established optimize its electrical performance by modifying density, filling ratio thickness. Also, dependence structure temperature variations number layers investigated.
