Tin (Sn)-based perovskites have garnered significant interest for their applications in perovskite transistors. Despite significant progress, Sn-based perovskites are still plagued by a propensity for rapid oxidation from Sn2+ to Sn4+, leading to unwanted self p-doping and reduced stability. In particular, two-dimensional (2D) Sn-based perovskites have higher stability than three-dimensional (3D) counterparts. In our study, we demonstrated that the strategic incorporation of porphyrin like additives, especially, effectively mitigates Sn oxidation in 2D perovskite films, thereby reducing defect density. Consequently, devices modified with these additives show improved ambient and electrical stability, enhanced photoresponse, and higher mobility, with film mobility increases of up to 5 cm2 V−1 s−1. Furthermore, the perovskite transistors exhibit non-volatile photomemory characteristics. Also, we use several different wavelength of light to stimulate our devices and tried many stimulate time. These enhancements, especially in photoresponse and air stability, render the modified devices as promising candidates for future photomemory technology applications.
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.
