文摘

A random plasmonic thin film solar cells is studied theoretically. Silver nanoparticles are randomly distributed through the active layer of solar cell. The Maxwell–Garnett effective medium theory is used to describe the optical properties. We have found an optimum situation in which maximum short circuit current density is obtained. The maximum EQE are found for Ag particles of 7.5 nm radius and filling fraction of 0.05.
