Abstract

The effect of silicon quantum wires (SiQWs) diameter of heterojunction solar cells based on SiQWs with rectangular cross sections and graphene (SiQWs/G) is investigated using a coupled optical and electrical model. It is found that SiQWs/G with small cross section area (d²=4 nm²) shows high efficiency. because, the band gap of SiQWs obtained from the distance of energy state of wave function of the lowest conduction bands and the highest valence bands increases as the wire diameter decreases. Also, the quantum confinement of SiQWs with small diameter results in a direct band gap of indirect bulk silicon band gap. on the other hand, SiQWs/G with large d² also shows high efficiency due to the better light absorption of larger surface area of SiQWs with larger d.
