Abstract:A carbon/CNT/MXene mixed electrode in CsPbBr3 solar cells provides a network structure and multi-dimensional charge transfer path, which effectively increases the conductivity of the carbon electrode and carriers transport.
MXenes have attracted increasing attention from the research community due to several unique properties that make them suitable for many applications. As a rapidly growing family of 2D transitional metal carbides and nitrides, they have demonstrated very promising properties in electrochemical devices. Recently, a few reports have emerged showing that MXenes have interesting optoelectronic properties. In this review, the fundamental properties of MXenes are discussed, especially those related to optoelectronic properties, and the recent reports on MXene‐based optoelectronic applications including photovoltaic, plasmonic, photodetector, phototransistor, and light‐emitting diode applications are reviewed. Last, and most importantly, a vision and a road map is articulated for the future research directions that make the most sense for this important class of materials.

“…Based on this strategy, the champion device 25 wt% delivered a PCE of 7.62% and outstanding stability in 80% RH(Fig.17h). Recently, Mi et al[164] incorporated 1-D structure carbon nanotubes (CNTs) and 2-D Ti 3 C 2 -MXene nanosheets into the carbon paste to facilitate the multi-dimensional charge transfer path. Owing to the improved carrier extraction and transport, a respectable PCE of 7.09%…”
In recent years, inorganic CsPbBr3-based perovskites have accomplished considerable progress owing to their superior stability under harsh humid environment.
“…As indicated in Fig. 5 e, the devices using the Ti 3 C 2 T x -incorporated electrodes exhibit improved performance compared with the devices employing the electrodes without Ti 3 C 2 T x [ 70 ]. Fig.…”
Section: Applications Of Mxenes In Solar Cellsmentioning
Application of two-dimensional MXene materials in photovoltaics has attracted increasing attention since the first report in 2018 due to their metallic electrical conductivity, high carrier mobility, excellent transparency, tunable work function and superior mechanical property. In this review, all developments and applications of the Ti3C2Tx MXene (here, it is noteworthy that there are still no reports on other MXenes’ application in photovoltaics by far) as additive, electrode and hole/electron transport layer in solar cells are detailedly summarized, and meanwhile, the problems existing in the related studies are also discussed. In view of these problems, some suggestions are given for pushing exploration of the MXenes’ application in solar cells. It is believed that this review can provide a comprehensive and deep understanding into the research status and, moreover, helps widen a new situation for the study of MXenes in photovoltaics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
