Special Issue Information

Dear Colleagues,

Perovskite optoelectronic conversion materials have quickly reached high energy conversion efficiencies in both solar cells and light-emitting diodes (LEDs). Numerous methods have been proposed to promote their possible commercialization with continuous improvements to optical properties. This Special Issue will concentrate on the science and engineering of device fabrication in terms of theoretical simulation, material synthesis, and performance study. We invite materials scientists, chemists, physicists, and engineers to discuss the science of and technology for perovskite nanostructure materials in solar cells and LEDs. Topics of particular interest include, but are not limited to:

methods for the synthesis of superior perovskite materials;
doped or non-Pb perovskite materials;
new device structures and performances;
optical and optoelectronic properties;
surface processing of perovskite materials;
stabilization of materials and devices;
carrier transportation mechanisms in device structures; and
theoretical calculations for and simulation of perovskite materials and devices.

All accepted papers will be published online with DOIs after peer review.

Dr. William Yu
Guest Editor

Abstract

In the process of preparing CsPbBr₃ films by two-step or multi-step methods, due to the low solubility of CsBr in organic solvents, the prepared perovskite films often have a large number of holes, which is definitely not conducive to the performance of CsPbBr₃ perovskite solar cells (PSCs). In response to this problem, this article proposed a method of introducing InBr₃ into the PbBr₂ precursor to prepare a porous PbBr₂ film to increase the reaction efficiency between CsBr and PbBr₂ and achieve the purpose of In (Ⅲ) incorporation, which not only optimized the morphology of the produced CsPbBr₃ film but also enhanced the charge extraction and transport capabilities, which was ascribed to the reduction of the trap state density and impurity phases in the perovskite films, improving the performance of CsPbBr₃ PSCs. At the optimal InBr₃ concentration of 0.21 M, the InBr₃:CsPbBr₃ perovskite solar cell exhibited a power conversion efficiency of 6.48%, which was significantly higher than that of the pristine device.

Application of MXenes in Perovskite Solar Cells: A Short Review

by Syed Afaq Ali Shah, Muhammad Hassan Sayyad, Karim Khan, Jinghua Sun and Zhongyi Guo

Abstract

Application of MXene materials in perovskite solar cells (PSCs) has attracted considerable attention owing to their supreme electrical conductivity, excellent carrier mobility, adjustable surface functional groups, excellent transparency and superior mechanical properties. This article reviews the progress made so far in using Ti₃C₂T_x MXene materials in the building blocks of perovskite solar cells such as electrodes, hole transport layer (HTL), electron transport layer (ETL) and perovskite photoactive layer. Moreover, we provide an outlook on the exciting opportunities this recently developed field offers, and the challenges faced in effectively incorporating MXene materials in the building blocks of PSCs for better operational stability and enhanced performance.
