Combination of near-field and scattering effects in plasmonic perovskite solar cell including cobalt doped nickel oxide HTL

Due to its bandgap tunability, a perovskite material is an effective option in the solar cells field. The inclusion of metallic nanoparticles in solar cells improves their efficiency. This paper investigates the effect of employing plasmonic nanospheres on the absorption, optical carrier generation rate, and photocurrent of perovskite solar cell. The effect of different numbers, radii, and locations of plasmonic Al nanospheres randomly embedded within the perovskite cell on the optical performance of the proposed perovskite solar cell was studied. The results showed that the proposed cell enhanced the optical absorption by 47%, the photocurrent by 8.2%, and the optical carrier generation rate by 20% compared to the reference cell. Using this proposed nanostructure with Al nanospheres within the cell enhances the optical performance of the perovskite solar cell due to the double contribution of near-field and scattering effects for plasmonic nanospheres. All numerical simulation results were obtained by a three-dimensional (3D) finite element method (FEM) using COMSOL software. The proposed structure reveals a new approach for future plasmonic perovskite solar cell designs for the renewable energy field.
