Degradation Mechanism of Perovskite under High Charge Carrier Density Condition
Guohui Li, Huihui Pi, Yanfu Wei +7
Extensive studies have focused on degradation of perovskite at low charge carrier density (<10^16 cm^-3), but few have surveyed the degradation mechanism at high charge carrier den…
Tungsten based Anisotropic Metamaterial as an Ultra-broadband Absorber
Yinyue Lin, Yanxia Cui, Fei Ding +4
The trapped rainbow effect has been mostly found on tapered anisotropic metamaterials (MMs) made of low loss noble metals, such as gold, silver, etc. In this work, we demonstrate t…
Beam Collimation Using an Anisotropic Metamaterial Slab without Any Nanometer-sized Aperture
Shou Zhang, Guohui Li, Yanxia Cui +4
Plasmonic beam collimation effect has been thoroughly investigated based on the well-known nanometer-scale bull's eye structure formed by complex and high-cost fabrication processe…
Efficiency Enhancement in Organic Solar Cells by Incorporating Silica-coated Gold Nanorods at the Buffer/Active interface
Haoyang Zhao, Fan Yang, Peiqian Tong +7
The performance of organic solar cells (OSCs) can be greatly improved by incorporating silica-coated gold nanorods (Au@SiO2 NRs) at the interface between the hole transporting laye…
Plasmonic and Metamaterial Structures as Electromagnetic Absorbers
Yanxia Cui, Yingran He, Yi Jin +6
Electromagnetic absorbers have drawn increasing attention in many areas. A series of plasmonic and metamaterial structures can work as efficient narrow band absorbers due to the ex…
Efficient multiband absorber based on 1D periodic metal-dielectric photonic crystals with a reflective substrate
Yanxia Cui, Wenyan Wang, Yingran He +7
We propose an efficient multiband absorber comprising a truncated one-dimensional periodic metal-dielectric photonic crystal and a reflective substrate. The reflective substrate is…
