Abstract :
The study found that surface plasmon resonance (SPR) can be excited by adding metal nanoparticles in thin-film solar cells (SCs). Then light can be concentrated and `folded´ into a thin semiconductor layer, thereby increasing the light absorption efficiency of solar cells. In this paper, we use the finite difference time domain method (FDTD) and combined with periodic boundary conditions (PBC) to model a two-dimensional (2-D) thin-film solar cell with periodic square metal nanoparticles. We calculate the light absorbed power of thin-film solar cells by adding metal particles, and also discuss the different sizes of metal particles influencing on the power of light absorption.
