Study on plasmonic effect of perovskite solar cells based on nanofilm structure

In this work, a theoretical analysis of plasmonic enhancement of Ag particles embedded in CaTiO3 thin-film layer for ZnO structure solar cells is presented. Due to the introduction of Ag particles, the absorption of solar cell is enhanced, owning to the strong surface plasmon absorption of Ag particles and synergistic effect between Ag and CaTiO3. In our analysis, the optimized radius of Ag particles is 80nm. The average absorption efficiency of the optimized nano- structure can achieve 80%, which is 24% higher than that of pure CaTiO3 thin-film layer structure. We believe the proposed Ag/CaTiO3 solar cells structure could be a potential candidate for future industry manufacture with low-cost and simple fabrication process.
