Color implementation of perovskite solar cells (PSCs) has become essential to satisfy the increasingly demanding aesthetic requirements. In this study, color implementation of highefficiency PSCs was realized by using AZO/Ag/AZO transparent multilayered electrodes in the bottom layer/metal layer/top optoelectronic controlling layer and by tuning the thickness of the top optoelectronic controlling layer through optical interference. The developed AZO/Ag/AZO transparent multilayered electrodes exhibited excellent electrical and optical properties with a high transmittance (94.96%), a low sheet resistance (6.09 Ω/sq), and controlled reflectance. We implemented four color (yellow, purple, blue, and green) perovskites by using AZO/Ag/AZO transparent multilayered electrodes. Furthermore, we fabricated PSCs with a high efficiency of 18.3% by optimizing AZO/Ag/AZO transparent multilayered electrodes. Therefore, a simple method was proposed to fabricate high-efficiency colored PSCs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
