Optimizing absorption and scattering cross section of metal nanostructures for enhancing light coupling inside perovskite solar cells

Metal-halide perovskite solar cells attracted more interest in last decade due to rapid enhancement in its efficiency from 3.9% in 2009 to over 20% in 2016 [1]. In this work, we studied theoretically effect of using silver nanostructures inside active layer of perovskite solar. Metal nanostructures could confine and guide electromagnetic waves at nanoscale dimensions, however these processes are highly depending on shape, dimension and type of used metal, by applying Mie's theory we could compare absorption and scattering cross section of many metal nanostructures to find optimum shape and dimensions for highest light confinement in small thickness of perovskite active layer.
