Two-dimensional transition metal carbides (MXenes) are of great interest for a range
of applications in electronics, including solar cells due to their tunable optoelectronic
characteristics, strong metallic conductivity, and attractive solution processability. In this study,
we used photo-conductive atomic force microscopy (pcAFM) to map the local (nanoscale)
photovoltaic performances of the Ti 3 C 2 T x MXene integrated TiO 2 electron transport layer (ETL)
based perovskite solar cells (PSCs) to determine the treatment's impact on the microscopic
charge flow inside the devices. The nanoscale photovoltaic performances of the devices with
MXene integrated ETLs is first studied by using the pcAFM technique. The underlying PV
mechanisms and their localized dependency on the interfacial modification across the layers
must be understood through the investigation of these photoresponses at the nanoscale. The
morphology and photocurrent maps with different applied voltages have been simultaneously
measured with nanoscale resolution from the top surfaces of the devices without back contacts.
Compared to the as-deposited samples, Ti 3 C 2 T x MXene based PSCs show a more uniform and
improved current flow throughout the film. Average local photocurrent for MXene-induced
PSCs is significantly larger than that of as-deposited PSCs at zero applied bias and steadily drops
as positive bias is raised until it reaches the open circuit voltage. Large variations in short-circuit
current were also observed at different locations across the film that appeared identical in
topography images. Our study reveals that MXene-integrated ETLs have the potential to improve
the polycrystalline photovoltaic devices' performance by enhancing the active layers' intrinsic
properties and nanoscale photoconduction.
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.
