Metal halide perovskites (MHPs) continue to redefine the landscape of solution-processed optoelectronics, yet their implementation remains hindered by instability, compositional fragility, and stringent synthesis requirements. This invited contribution presents an unconventional in situ synthesis framework that directly generates perovskite nanocrystals (NCs) within reactive inorganic–organic matrices under ambient, glovebox-free conditions.
The method exploits metal–organic scaffolds to guide NC nucleation and growth, enabling precise control over composition, dimensionality, and defect passivation across a broad range of halide (Cl⁻, Br⁻, I⁻) and A-site (Cs⁺, MA⁺, FA⁺) chemistries. The resulting nanocomposites display exceptional environmental stability, strongly suppressed defect densities, and near-unity photoluminescence quantum yields in selected systems. Incorporation of bulky organic cations extends the approach to low-dimensional and 0D lead-free perovskites, including highly robust Sn-based phases and Ag/Bi double-perovskite nanocrystals such as Cs₂AgBiBr₆, which additionally exhibit promising photocatalytic responses.

Because the chemistry proceeds at room temperature and is inherently compatible with roll-to-roll deposition, the platform provides a scalable and sustainable route for large-area perovskite manufacturing. Its reproducibility and tunability also make it well suited for automation and machine-learning-assisted discovery. Demonstrated applications span photovoltaics, LEDs, lasing [6], down-conversion, photocatalysis [4], and gas sensing, showcasing the potential of in situ synthetic design to expand the functional space of perovskite nanomaterials and enable new device architectures.

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.
