Proceedings of Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP27)
Publication date: 22nd October 2026
ABX3-type halide perovskites are a promising class of functional semiconductor materials from the perspectives of materials physics and optoelectronic applications, owing to their unique optical, electrical, and thermal properties. Their thin films, bulk single crystals, atomically thin two-dimensional (2D) quantum layers, and zero-dimensional (0D) quantum dots exhibit high photoluminescence (PL) quantum yields at room temperature. Lead halide perovskites are defect-tolerant semiconductors, exhibiting intrinsic free-carrier or free-exciton recombination PL [1,2]. Perovskites are also soft materials that display strong electron-phonon coupling [3], which induces carrier mass enhancement [4], phonon-bottleneck effects in hot-carrier relaxation [5], and efficient anti-Stokes PL [6]. Using high-quality 0D quantum dot samples, we have successfully demonstrated laser cooling of perovskite semiconductors through efficient anti-Stokes PL [7]. In addition, room-temperature ferroelectricity in 2D layers can be chemically engineered, and the coexistence of ferroelectricity and luminescence opens new avenues for nonlinear optoelectronic devices [8]. This talk discusses the fundamental semiconductor photophysics of lead halide perovskites.
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.
