Metal-halide perovskites offer an exceptional combination of tunable optoelectronic properties and versatile processing, making them promising materials for photovoltaics and emerging optoelectronic technologies. Thermal evaporation provides an attractive route toward scalable manufacturing while enabling precise control of composition, thickness, and interfaces.
In this talk, I will present our recent advances in vacuum-processed perovskites across different length scales and device concepts. Accelerated co-evaporation enables high-quality perovskite absorbers with substantially reduced processing times, addressing important requirements for scalable photovoltaic manufacturing.[1,2] Combined with low-damage sputtering of transparent electrodes, vacuum processing also enables ultrathin and semi-transparent solar cells, including functional devices with perovskite absorbers down to 10 nm.[3]
Beyond conventional solar cells, nanometer-scale control of sequentially deposited perovskite layers enables engineered heterostructures and multiple quantum wells. By controlling layer thickness, composition, and energetic alignment, these architectures provide new opportunities to manipulate carrier confinement, charge transfer, and optical response.[4,5]
These results highlight thermal evaporation as a versatile platform connecting scalable perovskite photovoltaics with ultrathin and low-dimensional optoelectronic devices.

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.
