Increased light scattering have been found to improve the short-circuit current of photovoltaic devices. In this paper we have tried to optimize the dimensions of ZnO nanorods to achieve this. Scattering efficiency of these nanorods was evaluated by solving Maxwell’s electromagnetic equation in the nanorods and surrounding perovskite using COMSOL Multiphysics software. For evaluation of scattering parameters the scattered field was integrated on the surface of nanorods. The scattering coefficient was found to increase with increase in radius.
