Metal halide perovskites have emerged as promising alternatives to traditional semiconductors, yet their practical implementation faces several challenges that limit their impact in society. In particularly, material stability and performance areas have been key aspects that affect perovskite photovoltaics as well as various semiconductor-based applications. Overcoming these obstacles necessitates precise tuning of the material, and strategies such as crystallization control or additive engineering become crucial.
Here, we introduce comprehensive approach to perovskite formation control that enable the optimization of the systems for specific applications. As a result, we design techniques such as an in-situ highly efficient nanocrystals fabrication approach through humidity-induced methods [1], additive adjustment for efficient and stable Pb-free perovskite solar cells, and a laser-based passivation of macrocrystal surfaces [2]. Through a thorough investigation into the physical properties of these monocrystals, we explore their impact on diverse applications, such as photovoltaic devices and memristors [3]. Leveraging the robustness of monocrystalline systems, we develop an impedance spectroscopy model to analyze the phase dispersion resulting from ionic modulation, providing valuable electrical insights applicable to polycrystalline thin-film devices. Our research contributes to advancing high-performance metal halide perovskite devices by elucidating crucial factors influencing their performance and proposing potential solutions to enhance their functionality.

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.
