Recently, two-dimensional (2D) MXenes materials have received enormous attention because of their excellent physiochemical properties such as high carrier mobility, metallic electrical conductivity, mechanical properties, transparency, and tunable work function. MXenes play a significant role as additives, charge transfer layers, and conductive electrodes for optoelectronic applications. Particularly, titanium carbide (TiCT) MXene demonstrates excellent optoelectronic features, tunable work function, good electron affinity, and high conductivity. The TiCT has been widely used as electron transport (ETL) or hole transport layers (HTL) in the development of perovskite solar cells (PSCs). Additionally, TiCT has excellent electrochemical properties and has been widely explored as sensing material for the development of electrochemical biosensors. In this review article, we have summarized the recent advances in the development of the PSCs using TiCT MXene as ETL and HTL. We have also compiled the recent progress in the fabrication of biosensors using TiCT-based electrode materials. We believed that the present mini review article would be useful to provide a deep understanding, and comprehensive insight into the research status.
近年来，二维（2D）MXenes材料因其优异的物理化学性质，如高载流子迁移率、金属导电性、机械性能、透明度和可调节的功函数，而受到广泛关注。MXenes作为添加剂、电荷转移层和光电应用的导电电极发挥着重要作用。特别是，碳化钛（TiCT）MXene表现出优异的光电特性、可调节的功函数、良好的电子亲和力和高导电性。TiCT在钙钛矿太阳能电池（PSC）的开发中被广泛用作电子传输层（ETL）或空穴传输层（HTL）。此外，TiCT具有优异的电化学性质，并已被广泛探索作为开发电化学生物传感器的传感材料。在这篇综述文章中，我们总结了使用TiCT MXene作为ETL和HTL的PSC开发的最新进展。我们还汇编了使用基于TiCT的电极材料制造生物传感器的最新进展。我们相信，这篇小型综述文章将有助于深入理解并全面洞察研究现状。
