Abstract :
Quantum electrodynamic model is proposed for a recently reported efficient single-wall carbon nanotube (SWCNT) photovoltaic device. In this model, nanotube is presented to the simulator through a set of parameters that gives quantum mechanical description of a semiconducting nanotube, as used in the device. Electromagnetic simulation of this device is also performed using ray tracing method and FDTD method. An incident light beam of 600 THz with linear polarization has been used for illumination. Silvaco´s Atlas device simulator is used to simulate the proposed quantum model and also to perform electromagnetic simulation. Field intensity inside the device and its I-V characteristics are found from simulated results, which reflect photovoltaic effect of the device.
