Abstract :

In this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (QESC) have been simulated and investigated. Optical path technic is used for simulation. The results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the QESC. Simulation results show that for optical paths with and  QE can be achieved to 72% which is approximately 12% more than . The simulation results with grating in SC and reflecting about 100% at the end of the device show that QE increase to ٪47 with which is more than the results of device without grating. So the results show that the QESC increase with increasing the dispersion angle and diffusion length in the grating device.
