The future of electronics, wearables, healthcare, and smart environments is being shaped by the integration of IoT (Internet of Things) with flexible technologies. A plethora of printed electronic components, including OLED displays, OPVs, TFTs, antennas, and diodes, among others, have already been developed [1], [2], [3]. These can then be integrated into technological platforms with a multitude of applications. When building such platforms, it is essential to address the question of energy autonomy. For flexible electronics, energy is normally harvested from the environment (solar energy, heat, movement, etc.) and stored in supercapacitors (SC) [4] 4. These energy storage devices are the optimal choice for printed and wearable electronics. They offer a long shelf life, seamless integration, and rapid charge and discharge capabilities. From many available options, MXenes have been regarded a good choice for SC manufacturing thanks to their optimal chemical properties. MXenes have a hydrophilic surface due to the presence of hydroxyl, oxygen, or fluorine functional groups (-OH, =O, -F), high electrical conductivity up to ~10,000 S/cm, especially for Ti₃C₂Tx, high flexibility, high capacitance (~1500 F/cm³ for Ti₃C₂Tx), fast ion transport, chemical stability, and more. As such, for the last couple of years, there has been a tremendous focus on MXene synthesis and implementation as SC electrodes [5], [6], [7].
This presentation will prove the vital importance of MXenes in the fabrication of SC electrodes for printed and flexible electronics. It will also show how they compare to other promising technologies and highlight their advantages and shortcomings. [8], [9]. It will also be discussed some strategies for MXene-based SC development to meet different applications requirements, such as voltage window, usable area and stability. However, the full potential of MXenes will only be exploited once the significant hurdles that currently stand in the way have been overcome, namely long-term stability and green synthesis. Nevertheless, due to their rich chemistry and optimal properties for electrochemical energy storage, MXenes are poised to play a significant role on powering up future and printed and flexible electronics.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
