To enable sustainable and low-cost energy conversion technology – the development of new energy conversion technology needs to be accelerated. In this talk, our approach to make use of scalable manufacturing methods to accelerate the optimization of process of functional materials research by combinatorial synthesis is described. We have been able to demonstrate to solution-based scalable combinatorial methods based on slot-die coating and inkjet printing [1,2]. We have managed to synthesize homogeneous combinatorially inkjet-printed samples of halide perovskite semiconductors [1,2] and evaluate the phase diagram and compositional homogeneities of these samples. Becoming involved in combinatorial science, we have also become very active and involved to set up materials databases and create tools enabling faster technology development in line with FAIRdata principles. We mobilized >90 scientist from our research community to help accumulate the information distributed over 17000 publication on the fabrication and resulting performance metrics in halide perovskite solar cells.[3] The resulting database - The Perovskite Database - with integrated interactive graphical tools for data visualization and searching hase been released (www.perovskitedatabase.com) and can now be made use for experimental data dissemination by the world-wide perovskite PV community. Another factor in accelerating materials development is the utilization and development of in-line process analytics, which enables us to gain direct feedback during materials processing to help find optimal process conditions and ink compositions faster. Futhermore, we have developed a high-throughput materials discovery platform based on slot-die coating (http://just.science/in-form/), which will enable high-throughput X-ray based synchrotron experimentation at the Balder beamline at MAXIV. A last but very important step is also the fabrication of larger area prototypes to enable the evaluation of new materials on a higher technology readiness level and the validation in real operating conditions. Based on slot-die coating, we have been able to manufacturing perovskite PV minimodules with >20% power conversion efficiencies, that we have also been able to encapsulate and try in an outdoor rooftop test station in Berlin. In all of our research activities we aim for early involvement of industrial partners to ensure direct pathways for technlogy transfer of our R&D.

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.
