The commercial deployment of metal halide perovskite photovoltaics hinges on bridging the gap between small-scale laboratory efficiencies and long-term operational stability at an industrial scale. Physical and chemical interfaces within these device architectures represent critical bottlenecks, governing non-radiative recombination, ion migration, and energetic misalignment. This talk presents a comprehensive approach to mastering these boundaries by controlling the buried heterojunction, understanding long-term surface evolution, and deploying multimodal strategies for scalable optoelectronic applications. First, we address the buried interface by introducing a multifunctional polymer matrix (sodium hyaluronate) to disperse SnO2 nanoparticles. This approach yields highly uniform, strain-relaxed perovskite films with eliminated oxygen vacancies, achieving a champion power conversion efficiency (PCE) of 25.11% and excellent ambient stability[1]. Second, we explore the dynamic nature of 2D/3D surface heterojunctions under long-term operation. We systematically trace the evolution of charge carrier dynamics as these interfaces age, demonstrating that controlled phase changes and the emergence of PbI2 crystals can naturally optimize interfacial band alignment, boosting the open-circuit voltage from 1.14 V to 1.18 V[2]. Finally, we translate these fundamental interface insights into functional, scalable technologies. By combining transfer matrix optical modeling with targeted molecular passivation (using 3-trifluoromethyl-1H-1,2,4-triazole), we overcome the transparency-efficiency trade-off in semi-transparent perovskite solar cells for building-integrated photovoltaics and indoor electronics. This framework achieves a record indoor PCE of 22.41% under 1000 lux illumination and successfully scales to a 30 x 30 cm2 semi-transparent module [3]. Together, these interlinked interfacial strategies provide a clear, industrially compatible roadmap toward highly stable, next-generation perovskite technologies.

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.
