Abstract
The aim of this work is to reveal by in silico methods the topological regularities of controlling the photovoltaic properties of mono- and bilayergraphene / carbon nanotube (CNT) composite films with a covalent bonding of a nanotube and a graphene sheet. The studies were carried out for supercells of mono- and bilayer graphene / CNTs composites with CNTs (10,0) and (12,0) at distances between the tubes of 10 and 12 hexagon. The photovoltaic properties were investigated by analyzing the profile of the spectra of the maximum photocurrent in the wavelength range λ from 280 to 2000 nm (with a step of 10 nm). Photocurrent spectra were calculated on the basis of absorption and solar radiation spectra.
