Plasmonic particles have unique optical properties which can make an increasing of the absorption coefficient in solar cells. Also, the absorption coefficient increases by using Bragg mirrors in solar cells. In this article, in order to increase the light absorption of thin film solar cell, a novel structure in which silver and aluminum nanoparticles, a silicon nano-cylinder array and Bragg mirrors are used, is presented. The influences of Bragg mirror, silicon nano-cylinder array and the size of plasmonic particles are investigated by finite difference time domain (FDTD) method. The results show the significant increasing in the light absorption due to the formation of the local surface plasmon nanoparticles. The transmitting light is reflected to the silicon layer and thus the light absorption will be increased. Also, silicon nano-cylinder array traps the incident light and improves the light absorption. The amount of short circuit current density and the efficiency for the proposed structure are achieved 37.38mA/cm2 and %18.37, respectively. So, the results revealed that the proposed structure exhibits significantly better performance in compared with the other existing structures.
