Current research in thin-film deposition emphasizes compatibility with large-scale manufacturing, reproducibility, and uniformity. Although thermal vacuum deposition has long been established in the semiconductor and OLED industries, applying this technique to hybrid perovskite materials remains particularly challenging. The complexity arises primarily from their unconventional sublimation behaviors, characterized by abnormal adsorption dynamics and difficulties in precise process control. In this presentation, I will first elucidate the distinctive sublimation mechanisms and deposition kinetics associated with hybrid perovskites, highlighting how these differ fundamentally from traditional thermal evaporation of conventional inorganic materials. Subsequently, I will introduce our novel solutions to overcome these challenges, including the implementation of a meticulously designed deposition protocol combined with a specifically tailored evaporator system capable of real-time, precise process control. Leveraging these advancements, we successfully fabricated perovskite solar cells with power conversion efficiencies exceeding 25% in conventional n-i-p architectures, demonstrating remarkable batch-to-batch reproducibility. Additionally, I will discuss our recent progress on vacuum-deposited modules exceeding 200 cm², illustrating the significant industrial interest and considerable potential of vacuum-based techniques for perovskite photovoltaic commercialization.
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.
