characterized by the formula (LA)2(A)n−1PbnX3n+1. Here, LA represents a long-chain organic interlayer (spacer) cation, while A denotes a small intralayer cation (in the perovskite cage), X is a halide anion, andnis an integer indicating the number...
Enhanced Efficiency and Stability of Perovskite Solar Cells via Anti-Solvent Treatment in Two-Step Deposition Method The low-cost inorganic鈥搊rganic lead halide perovskite materials become particularly promising for solar cells with high photovoltaic conversion efficienc... M Li,X Yan,Z Kang,... ...
Herein, we experimentally demonstrate the formation of lead halide perovskite (MAPbX3) based hybrid plasmonic nanolasers and nanolaser arrays with arbitrary cavity shapes and controllable lasing wavelengths. These spasers are composed of MAPbX3 perovskite nanosheets, which are separated from Au patterns ...
The ever-growing field of photovoltaics has witnessed the rapid success of halide perovskites in achieving a high power conversion efficiency (PCE) over 25%1,2. Perovskite solar cells (PSCs), typically based on a solution-processed perovskite layer with a film thickness of a few hundred nanomet...
An organic or inorganic monovalent A+ cation and a divalent B2+ metal cation are generally seen corresponding to the 1− charge of the halide anion. The hybrid organic–inorganic halide perovskite (hybrid perovskite), most commonly denoted as CH3NH3PbI3 (MAPbI3), often has the A site ...
Understanding the origins and evolution of inhomogeneity in halide perovskite solar cells appears to be a key to advancing the technology. Time-of-flight secondary-ion mass spectrometry (TOF-SIMS) is one of the few techniques that can obtain chemical information from all components of hybrid organic...
Copper oxide as inorganic hole transport material for lead halide perovskite based solar cells The use of inorganic layers as hole transport materials (HTM) has been suggested to enhance the resistance to degradation of methylammonium lead halide per... MI Hossain,FH Alharbi,N Tabet - 《Solar ...
Point defects in metal halide perovskites play a critical role in determining their properties and optoelectronic performance; however, many open questions remain unanswered. In this work, we apply impedance spectroscopy and deep-level transient spectros
