Chapter 22 - Plasmonic Perovskite Solar Cells Utilizing Noble Metal–Metal Oxide Hybrid Nanoparticles

Abstract

The analysis of optical properties noble metal–metal oxide core–shell hybrid nanoparticle has long been of interest due to its surface plasmon resonance (SPR) properties. These SPR properties are being used to enhance the performance of many optical and electrical devices wherein thin film is one of them. We have used the metal–metal oxide core–shell nanoparticles to study the optical properties like extinction cross-section and SPRs inside perovskite active medium. We have developed a semianalytical model to find out the dipolar, quadrupolar polarizability in both coated and noncoated situation and their influences on the optical cross-section. The comparison between two metals (silver and aluminum) in coated and noncoated situations has been done in terms of SPRs, which shows different spectral width with peak positions that can be utilized to increase the exciton generation rate in perovskite material.
