Halide perovskites are forerunners for next-generation photovoltaics and light-emitting devices. The power conversion efficiencies of perovskite solar cells have exceeded 25%, while that of the external quantum efficiencies of perovskite light emitting devices have also breached the 20% mark. Their remarkable rise is driven by exceptional properties such as large absorption cross-sections, defect tolerance, significant spin-orbit coupling, long balanced charge diffusion lengths, slow hot carrier cooling, ion migration, and radiation tolerance etc. Furthermore, their versatile structures and diverse dimensionalities afford new levers for tunning their photophysical properties. Consequently, their applications have rapidly expanded beyond traditional optoelectronics into areas such as spintronics, radiation detectors, memristors, bioimaging, and quantum light sources. Of late, low dimensional halide perovskites have demonstrated great promise as single photon sources as well as bunched multiphoton sources. In this talk, I will focus on our recent efforts on the basic photophysics studies and engineering of perovskite quantum emitters [1-5].

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.
