Tuning of electron transport layers using MXene/metal–oxide nanocomposites for perovskite solar cells and X-ray detectors

Abstract

This work elaborates on the decoration of metal oxides (ZnO and Fe3O4) between MXenes sheets for use as the supporting geometry of PCBM electron transport layers (ETLs) in perovskite solar...

The dawn of MXene duo: revolutionizing perovskite solar cells with MXenes through computational and experimental methods

“…This doped MXene promotes the development of a double perovskite layer with high crystallinity as compared to 10c, it shows the lowest surface roughness and enhanced charge transport, and it leads to improved efficiency of 13.31% (MXene/ZnO) and 13.79% (MXene/Fe 2 O 3 ) for p-i-n device. 171 In addition, MXene serves as a buffered layer between the charge transport layer and contacts or substrate to prevent adhesion issues and uneven surface arrangement, which are common problems during the preparation process of the layer ETL. These issues might result in a decrease in device performance.…”

Performance Enhancement and Stability Improvement in Perovskite Solar Cells via Interface Functionalization

“…H.S. Kim et al explored the addition of MXene/TMSO nanocomposites (MXenes: transition metal carbides, nitrides, or carbonitrides having a two-dimensional layered structure) to modify the PCBM ETL and further boosted the performance (PCE and long-term stability) of inverted perovskite solar cells (p-i-n PSCs) [21].…”

A novel heterojunction layer-assisted interfacial defect control strategy for high-performance solar cells

“…6–8 To overcome these obstacles, optimization of key components, such as the interface layer and the electron transport layer, has been suggested as a crucial approach to enhancing the performance of perovskite solar cells. 9–11…”

“…[6][7][8] To overcome these obstacles, optimization of key components, such as the interface layer and the electron transport layer, has been suggested as a crucial approach to enhancing the performance of perovskite solar cells. [9][10][11] g-C 3 N 4 is an organic semiconductor polymer that is free from metal and possesses a 2D structure consisting of repeated triazine rings. 12 Its creation involves the use of affordable and readily available precursors such as melamine or urea.…”
