Perovskite nanocrystals have further increased the scientific interest developed around the photophysical properties of these semiconductors. Their technological potential has generated a strong impulse towards the optimization of their synthesis to overcome stability problems and improve control over shape and size and therefore their optoelectronic behavior. Among the alternatives proposed for the preparation of these materials in the nanoscale, the template method has proven to be an interesting and effective solution [1]. By making use of porous matrices, it is possible to spatially confine the semiconductor growth by exploiting the pores as nanoreactors in which the actual synthesis takes place. In this way it is possible to obtain, for example, composite materials in the form of thin films, containing nanocrystalline perovskites and suitable for integration into a device, as has already been reported in some cases [2], [3].
In this context, the analysis of the process of formation of nanocrystals within the porous structures constitutes an important support for the optimization of both the fabrication and the optoelectronic quality of the perovskites. In the work presented here, we examined the growth of nanocrystalline perovskites in a porous matrix obtained with the stratification of silica particles [4]. The optical transparency of the layer allows the possibility to use the photoluminescence of the perovskites as a diagnostic tool in order to monitor their growth within the porous network. This type of system has also allowed us to analyze the effect of other factors that can take part in the process such as the temperature, light illumination and concentration of the perovskite precursors. Finally, through the experimental study we described the growth dynamic through a theoretical modeling in which the possible phases that govern the formation of the perovskites confined in the matrix are discussed. Based on the analysis presented in this work, indications and recommendations are proposed to improve the strategy for the synthesis of lead halide perovskites nanocrystals.

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.
