Proceedings of Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP20)

Perovskite solar cells have been attracting increasing attention during half a decade. The control of the crystal structure and analysis of crystallization dynamics of perovskite is very important research topic from the both standpoint of fundamental analysis and device application. We have been focusing on the fabrication control of perovskite in vacuum by laser deposition method [1]. The use of laser for the deposition of CH3NH3I is beneficial for the deposition-rate control. We also conducted crystallization dynamics analysis of perovskite by grazing incident X-ray diffraction (GIXD) at SPring-8 [2]. In this presentation, we would like to report our recent research results for crystallization control and real-time analysis of CH3NH3PbI3 perovskite deposition.
We designed special vacuum chamber where laser deposition and GIXD measurement can be conducted simultaneously. The chamber was installed at BL46XU in SPring-8 and crystallization dynamics of the deposition process of perovskite was analyzed. Firstly, we found that alternative deposition process, where PbI2 and CH3NH3I were deposited alternatively, results in c-axis oriented perovskite crystal. Additionally, in the PbI2 deposition process, Laue oscillation was observed, which represents the construction of smooth surface. Crystallization dynamics from PbI2 to CH3NH3PbI3 was observed including lattice constant change during the reaction. These results provide the insights into the understanding the perovskite deposition process.

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.
