SC10–Plasmonic enhancement of light-harvesting efficiency in Perovskite solar cells embedding Ag nanorods

Perovskite solar cells have attracted great attention in recent years due to its advantageous features including low production cost. Incorporation of plasmonic metal nanocrystals is a promising approach for broadening and enhancing the light harvesting of Perovskite solar cells. In this paper, we report a facile and versatile route to tune the photoresponse of perovskite via embedding Ag nanorods with multiplexed length-to-diameter aspect ratios. Plasmonic Ag nanorods with length-to-diameter aspect ratio of 2 and 3 are embedded, exhibiting their plasmon peak at 789 nm and 798 nm, respectively. Furthermore, the mechanism of the absorption has been discussed.
