Proceedings of Asia-Pacific Conference on Perovskite, Organic Photovoltaics&Optoelectronics (IPEROP25)
Publication date: 17th October 2024
Metal halide perovskites have gained significant attention over the past decade due to their exceptional optoelectronic properties, low production costs, and ease of fabrication. In photovoltaic applications, such as solar cells, remarkable power conversion efficiency of perovskite devices has been achieved, exceeding 26% for single junctions and 33% for tandem solar cells [1]. However, their performance and stability are significantly impacted by the presence of structural defects in both the bulk and interfaces of the perovskite layers. These defects facilitate nonradiative recombination, reducing efficiency, and/or contribute to material and device degradation over time [2]. A detailed understanding of mechanisms behind perovskite growth, defect formation evolution, and their possible passivation during the deposition process is crucial to address these challenges.
In this work, we employ in situ photoluminescence spectroscopy during the vacuum co-deposition of wide-bandgap perovskite to study the evolution of defect density. This approach provides real-time insights into the dynamics of perovskite growth, optoelectronic properties, and defect formation. Moreover, it offers a direct perspective of the interface and bulk passivation methods applied. We believe that such a real-time study is a powerful and versatile tool for the optimization of perovskite fabrication and the passivation of defects.
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.
