Quantifying Efficiency Loss of Perovskite Solar Cells by a Modified Detailed Balance Model
Wei E. I. Sha, Hong Zhang, Zi Shuai Wang +5
A modified detailed balance model is built to understand and quantify efficiency loss of perovskite solar cells. The modified model captures the light-absorption dependent short-ci…
Exploring the Way to Approach the Efficiency Limit of Perovskite Solar Cells by Drift-Diffusion Model
Xingang Ren, Zishuai Wang, Wei E. I. Sha +1
Drift-diffusion model is an indispensable modeling tool to understand the carrier dynamics (transport, recombination, and collection) and simulate practical-efficiency of solar cel…
Exciton delocalization incorporated drift-diffusion model for bulk-heterojunction organic solar cells
Zi Shuai Wang, Wei E. I. Sha, Wallace C. H. Choy
Modeling the charge-generation process is highly important to understand device physics and optimize power conversion efficiency of bulk-heterojunction (BHJ) organic solar cells (O…
Polarization Control by Using Anisotropic 3D Chiral Structures
Menglin L. N. Chen, Li Jun Jiang, Wei E. I. Sha +2
Due to the mirror symmetry breaking, chiral structures show fantastic electromagnetic (EM) properties involving negative refraction, giant optical activity, and asymmetric transmis…
Strongly Enhanced and Directionally Tunable Second-Harmonic Radiation by a Plasmonic Particle-in-Cavity Nanoantenna
Xiaoyan Y. Z. Xiong, Li Jun Jiang, Wei E. I. Sha +4
Second-harmonic (SH) generation is tremendously important for nonlinear sensing, microscopy and communication system. One of the great challenges of current designs is to enhance t…
Unidirectional and Wavelength Selective Photonic Sphere-Array Nanoantennas
Yang G. Liu, Wallace C. H. Choy, Wei E. I. Sha +1
We design a photonic sphere-array nanoantenna (NA) exhibiting both strong directionality and wavelength selectivity. Although the geometric configuration of the photonic NA resembl…
