Investigation and Numerical Analysis of the Effect of Size, Distance, Position, and Composition of Plasmonic Nanostructures on the Absorption of Perovskite Solar Cells

One of the main capabilities of the perovskite solar cell is their high absorbability in the visible range. However, they have low absorption coefficient in the infrared region, which is a large part of the solar spectrum in this area, as well as the toxicity of perovskite compounds. Metal nanoparticles have been introduced to overcome this problem. In this research, we studied the effect of size, distance, position, and composition of plasmonic nanostructures on light absorption, optical current, short-circuit current density, and maximum generation rate in perovskite solar cells. The results revealed that the optical properties mentioned above will be enhanced up to 1.33 times, compared to the reference state in which no nanoparticles are present, by using silver nanoparticles with 50 nm radius and 20 nm distance. In the following, different thicknesses of the absorbent layer were examined, as thickness has a direct relationship with the absorbent layer toxicity
