Proceedings of Asia-Pacific Conference on Perovskite, Organic Photovoltaics&Optoelectronics (IPEROP25)
Publication date: 17th October 2024
Perovskite solar cells have emerged as a cutting-edge research field in the realm of new-generation photovoltaic technologies, owing to their remarkable performance potential and the promise of cost-effective production. As of 2024, these cells have achieved an impressive power conversion efficiency exceeding 26%, surpassing conventional solar cell technologies like CIGS or amorphous Si. To push their performance further beyond the Shockley–Queisser limit, which hovers around 30%, a deep understanding of the physical chemistry rooted in crystallography becomes imperative.
Here in this research, we directly confirmed that specific grain boundaries in organometal halide perovskites impede charge carrier flow. To address this, we introduced a new fabrication technique: rapid cooling (quenching) of the crystallographic phase of the organometal halide perovskite, which effectively minimizes microscale defects such as grain boundaries. To further investigate the details and impact of grain boundaries in organometal halide perovskites, we performed TEM and in situ current density−voltage (J−V) analyses. These analyses revealed that a significant physical gap, originating from the grain boundaries of MAPbI3 perovskite, severely obstructs charge carrier flow. As a result, we achieved a power conversion efficiency (PCE) of 20.23% with a single-cation MAPbI3 PSC. The restricted crystallographic transition was demonstrated through scanning electron microscopy (SEM) images and confirmed by X-ray diffraction (XRD) analyses.
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.
