Perovskite solar technology has rapidly demonstrated its commercial potential within just over ten years of intense research efforts worldwide. Its remarkable attributes, including high specific power, cost-effective production, and superior performance in low-light conditions, have significantly enhanced its value across various applications, distinguishing it from other photovoltaic technologies. Hybrid organic-inorganic perovskites merge the benefits from both realms: the ease of solution processing inherent in organic small molecules or polymeric semiconductors, as seen in organic polymer solar cells, and the exceptional physical characteristics of high-performance (poly or single)-crystalline inorganic semiconductors. This fusion creates a single material class that encompasses the advantages of both.
Sustainable, safe and industry compatible processing routes are paramount to enable large scale production of perovskite photovoltaics. Green and sustainable perovskite photovoltaics are not only enabled by the choice of processing, but sustainability starts already at the material level!
Sustainable perovskite precursor synthesis is enabled by novel and innovative green halide chemistry developed by Solaveni in Germany.[1] In this talk, the advantages of the novel synthesis routes for organic alkylammonium halides as well as metal halides (PbX2, SnX2; X= halide) are highlighted and benchmarked from an LCA perspective against the conventional production routes. The LCA analysis delves into the specific environmental impacts of these precursor materials, assessing factors such as resource consumption, energy use, and emissions, offering critical insights into their sustainability profiles and contributing to the overall understanding of the ecological footprint associated with such materials.
Furthermore, we present the latest developments in lead-free tin halide perovskite solar modules obtained via industry compatible coating techniques using Solaveni’s custom made SnI2 inks.[2]

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.
