Development of scalable and environmentally friendly manufacturing methods is a necessity to realize the large-scale production and commercialization of perovskite solar cells. Gravure printing is a method suitable for large-scale roll-to-roll manufacturing of patterned layers.
In this work we present gravure printing of FA0.83Cs0.17Pb(I0.9Br0.1)3 perovskite from dimethyl sulfoxide (DMSO) with starch as a rheological modifier. Starch increases perovskite ink viscosity and helps with perovskite film growth, enabling processing in one step without anti-solvent quenching. [1] We use DMSO as the only solvent, which was found to have the lowest impact for both human health and environment when compared to other common solvents for perovskite processing. [2]
We discovered that the viscosity of the perovskite ink can be tuned not only by the amount of starch but also by aging of the ink and modifying ink preparation conditions. This was found to have a strong impact on the homogeneity of the printed perovskite layer and thus also to the cell performance. The longer heating time during dissolution resulted to similar results with the aging of the ink.

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.
