This paper presents the design of an optimized and efficient nanocone array solar cell. With the help of two approaches, it is possible to achieve the best performance for nanocone solar cells. They are adding shell to nanocones and extracting optimal design parameters such as nanocone height, shell layer thickness and bottom diameter. Indium phosphide nanocones are covered with a layer of ZnO material as a shell layer. The goal of maximizing the current density of the nanocone solar cell has been achieved by the particle swarm optimization algorithm. Our demand is met by achieving a short circuit current density of 35.08 mA/cm2 and a power conversion efficiency (PCE) of 27.1%, which achieves a performance improvement of nearly 18% compared to the non-optimized structure. Comparison of performance parameters such as optical absorption, electric field distribution, efficiency and calculated current density of the optimal design with non-optimal structure and other studies have been done. In another comparison of the obtained results, the improved performance of the optimized nanocone core–shell solar cell compared to other similar nanostructures has been confirmed.
